Outdoor Research Skytour Ascentshell Jacket

Finding Freedom in the Backcountry with Technical Protection You Can Trust

After five seasons of backcountry adventures, countless summit attempts, and more than my fair share of unexpected weather patterns, I’ve developed a rather discerning eye when it comes to mountain apparel. Let me tell you why the Outdoor Research Skytour Ascentshell Jacket has become my go-to shell for everything from mid-winter ski touring to spring alpinism—and why it might deserve a place in your gear closet too.

As someone who spends more weekends above treeline than below it, I’ve come to understand that the perfect backcountry shell balances waterproof protection with exceptional breathability—a combination that’s surprisingly difficult to find in a single garment. The Skytour Ascentshell isn’t just another entry in a crowded market; it represents Outdoor Research’s thoughtful response to the needs of serious mountain enthusiasts who demand technical performance without compromise.

The Technology Behind the Shell: Understanding Ascentshell

Before diving into my experiences with the Skytour, let’s unpack what makes Outdoor Research’s proprietary Ascentshell technology different from other waterproof-breathable membranes on the market.

Unlike traditional waterproof membranes that rely on a microporous structure, Ascentshell uses an electrospun membrane that creates an air-permeable, waterproof barrier. This means moisture vapor can escape much more efficiently while still keeping precipitation out. The science is fascinating—essentially, the membrane consists of millions of microscopic polyurethane fibers that are randomly arranged, creating countless pathways for sweat vapor to escape while being too convoluted for water droplets to penetrate.

What does this mean for us in the real world? Simply put, it means you can work harder without turning your jacket into a personal sauna. Having tested this jacket in everything from howling February blizzards to unexpected April downpours, I can confidently say that the Ascentshell membrane performs remarkably well in varied conditions.

First Impressions: Design and Construction

The moment I unpacked my Skytour jacket (I chose the Cobalt/Naval Blue colorway, though it comes in several appealing options), I was struck by its thoughtful design. At 19.9 ounces (564g) for a men’s medium, it hits a sweet spot—substantial enough to inspire confidence yet light enough not to weigh down your pack when the sun comes out.

The 70-denier nylon face fabric feels robust without being stiff or crinkly—a common complaint with hardshell jackets. There’s a pleasant softness to the material that doesn’t sacrifice durability, and after multiple seasons of abuse including tree branches, backpack straps, and the occasional rock scramble, mine shows remarkably little wear.

The jacket features a slightly relaxed fit that I appreciate for layering flexibility. It’s not boxy by any means, but there’s enough room to accommodate a midweight down jacket underneath when temperatures plummet. The articulated sleeves and ergonomic patterning ensure freedom of movement, which becomes immediately apparent when reaching for holds or pole plants on steep terrain.

Weather Protection: Standing Up to the Elements

Let’s address perhaps the most fundamental question about any mountain shell: does it actually keep you dry? After extensive field testing across varied conditions, I can report that the Skytour Ascentshell provides excellent weather protection, though with some nuances worth understanding.

In sustained moderate precipitation—the kind you might encounter during a day-long spring tour or an autumn alpine approach—the Skytour performs admirably. Water beads and rolls off the DWR (Durable Water Repellent) treated exterior, and the membrane prevents any moisture from reaching your mid-layers.

In truly torrential conditions, such as the unexpected thunderstorm that caught my group on an exposed ridge last May, I noticed some slight dampness at the shoulders after about two hours of continuous heavy rain. This isn’t uncommon for air-permeable membranes, which typically trade a small degree of absolute waterproofness for significantly improved breathability.

The fully taped seams prevent any leakage at potential weak points, and the waterproof YKK AquaGuard zippers have never allowed a drop through, even in driving rain. The helmet-compatible hood deserves special mention—its generous cut accommodates both climbing and ski helmets, while the laminated wire brim and three-way adjustability ensure excellent visibility and protection even in blustery conditions.

Wind resistance is another area where the Skytour excels. During a particularly brutal January day at 11,000 feet with 40+ mph gusts, the jacket blocked wind completely, allowing my insulating layers to do their job effectively.

Breathability: The True Test of a Backcountry Shell

For active mountain pursuits, breathability might actually be more important than absolute waterproofness. After all, becoming soaked from the inside due to trapped perspiration can be just as dangerous and uncomfortable as external precipitation.

This is where the Skytour Ascentshell truly shines. During high-output activities like steep skinning or bootpacking, the air-permeable membrane allows a noticeable amount of moisture vapor to escape—significantly more than traditional hardshells I’ve used in the past.

On a particularly grueling 3,000-foot skin track in the Colorado backcountry, I was able to keep the jacket on for the entire ascent without overheating—something I’ve rarely experienced with other waterproof shells. The large underarm pit zips provide additional ventilation when needed, extending the temperature range in which the jacket remains comfortable.

That said, no waterproof membrane is as breathable as a dedicated softshell, and there are still situations where I find myself shedding the Skytour in favor of more breathable layers during particularly intense activity in dry conditions. The key difference is that the threshold at which this becomes necessary is much higher than with traditional hardshells.

Feature Set: Thoughtful Details for Mountain Users

Outdoor Research has clearly designed the Skytour with input from actual mountain professionals, as evidenced by the thoughtful feature set that enhances functionality without unnecessary complications:

Pockets and Storage

The pocket configuration strikes an excellent balance between utility and simplicity. Two large, high-set hand pockets remain accessible while wearing a harness or hipbelt, while the single chest pocket perfectly accommodates a smartphone or small navigation device. The internal mesh drop pocket is ideal for storing gloves or skins while transitioning.

Hood Design

As mentioned earlier, the helmet-compatible hood is exceptionally well-designed. The three adjustment points allow for a customized fit with or without a helmet, and the laminated wire brim maintains its shape in harsh conditions, keeping precipitation off your face and maintaining visibility.

Powder Skirt

The integrated, removable powder skirt is a welcome feature for deep days. It secures snugly around your waist and includes loop attachments that connect to compatible pants, creating a snow-proof seal. When not needed, it can be removed entirely to save weight, which I appreciate for spring ski mountaineering.

Cuffs and Hem

The hook-and-loop cuff closures are simple and effective, sealing out snow while accommodating various glove styles. The drawcord hem adjustment allows for a customized fit at the waist, preventing drafts and snow entry during tumbles (we’ve all been there).

Ventilation

The previously mentioned pit zips extend from mid-chest to elbow, providing extensive ventilation options. The two-way zipper allows for precise adjustment depending on conditions and activity level.

Performance by Activity: Versatility in Action

One of the Skytour’s greatest strengths is its versatility across different mountain activities. Here’s how it performs in various scenarios:

Backcountry Skiing and Snowboarding

This is where the Skytour feels most at home. The combination of weather protection and breathability makes it ideal for touring, while the powder skirt, helmet-compatible hood, and ski-specific features enhance the experience on descents. The slightly relaxed fit accommodates layers without restricting movement during turns or transitions.

Alpine Climbing

The durable construction and articulated patterning make the Skytour a solid choice for alpine climbing. The hood fits well over a climbing helmet, and the high pockets remain accessible while wearing a harness. The breathability is particularly appreciated during strenuous pitches.

General Mountaineering

For approaches, summits, and descents, the Skytour provides reliable protection without the weight penalty of heavier expedition shells. The breathability means you’re less likely to overheat during strenuous sections, reducing the need to constantly adjust layers.

Resort Skiing

While primarily designed for backcountry use, the Skytour performs admirably at the resort as well. The powder skirt and hood work just as effectively inbounds, and the durable construction stands up to chairlift abrasion and the occasional tumble on hardpack.

Comparing to the Competition: Ascentshell vs. GORE-TEX and Others

The natural comparison for the Skytour Ascentshell is with GORE-TEX jackets, particularly those using GORE-TEX Pro or the newer GORE-TEX Active membranes. Having owned and extensively used shells with both technologies, I can offer some perspective on the differences.

GORE-TEX Pro shells typically offer slightly more robust waterproofing in truly extreme conditions, but at a significant cost to breathability. For sustained, torrential precipitation (think Southeast Alaska or the rainforests of the Olympic Peninsula), GORE-TEX Pro might have a slight edge in keeping you absolutely dry.

However, for the vast majority of backcountry scenarios—where activity levels fluctuate and conditions vary throughout the day—I find the Ascentshell membrane to be more versatile and comfortable. The breathability advantage is substantial, reducing internal condensation and allowing for more continuous wear during high-output activities.

Compared to other air-permeable membranes like Polartec NeoShell or eVent, the Ascentshell performs similarly in terms of breathability while maintaining competitive waterproofness. The overall construction quality of the Skytour, however, sets it apart from many competitors using similar membrane technologies.

When considering value, the Skytour presents an attractive proposition. At approximately $349 MSRP (though sales can bring this down significantly), it offers performance comparable to jackets costing $100-200 more from premium brands.

Sizing and Fit: Finding Your Perfect Match

The Skytour features what Outdoor Research calls a “Standard Fit,” which I’d describe as slightly relaxed without being boxy. For reference, I’m 5’11”, 175 lbs with a 42″ chest, and the medium fits me perfectly with room for layers underneath.

If you’re between sizes or prefer a trimmer fit, consider sizing down. Conversely, if you regularly wear thick insulation or have a broader build, your regular size should provide adequate room. The articulated sleeves and shoulders provide excellent mobility regardless of sizing.

For women, the Skytour Women’s model offers a specifically tailored fit with the same technical features and performance characteristics, available in sizes XS through XL.

Long-Term Durability: Standing the Test of Time

After multiple seasons of regular use, my Skytour shows impressive durability. The 70D nylon face fabric has withstood countless encounters with tree branches, pack straps, ski edges, and rock without significant wear or tears.

The DWR treatment has diminished somewhat over time, as expected with any water-resistant coating, but can be refreshed with appropriate wash-in or spray-on products. The membrane itself continues to perform well, with no noticeable decrease in waterproofness or breathability.

Zippers, cords, and adjustment points all function as they did when new, which speaks to the quality of components used. The interior lining fabric shows minimal pilling or wear, even in high-abrasion areas like the shoulders and cuffs.

Care and Maintenance: Extending the Lifespan

To maintain optimal performance from your Skytour Ascentshell jacket, follow these care guidelines:

1. Wash periodically using a technical cleaner designed for waterproof garments (like Nikwax Tech Wash) to remove dirt, oils, and contaminants that can impair breathability and water repellency.
2. After washing, reapply DWR treatment when you notice water beginning to absorb rather than bead on the surface. I recommend using Nikwax TX.Direct or a similar product specifically designed for technical shells.
3. Always follow the garment’s specific care instructions, which typically involve machine washing on gentle with cold water and tumble drying on low to reactivate the DWR coating.
4. Store your jacket clean and dry, hung up rather than compressed, to maximize membrane longevity.
5. For stubborn stains or particularly dirty areas, spot clean rather than increasing wash frequency, as excessive washing can accelerate DWR deterioration.

Proper care will substantially extend the functional lifespan of your investment and maintain optimal performance in the field.

The Full Spectrum: Available Colors and Styles

The Skytour Ascentshell comes in a range of colorways that balance visibility with style. Current options include:

For Men:

• Cobalt/Naval Blue (my choice)
• Black
• Cypress (olive green)
• Madder (deep red)
• Pewter/Black

For Women:

• Black
• Celestial Blue
• Clay/Burgundy
• Pewter

The color selection offers enough variety to express personal preference while maintaining the practical considerations of mountain apparel. The two-tone designs add visual interest without appearing overly flashy in the backcountry.

Where to Purchase: Finding the Best Value

The Outdoor Research Skytour Ascentshell Jacket is available through multiple channels:

• Directly from Outdoor Research’s website
• Major outdoor retailers like REI, Backcountry, and Moosejaw
• Local specialty outdoor shops

While the MSRP hovers around $349, patience can yield significant savings. End-of-season sales often discount the jacket by 25-30%, and previous season colors can sometimes be found for even less.

If possible, I recommend trying the jacket on in person to confirm sizing and fit preferences before purchasing. Many retailers offer generous return policies if ordering online isn’t possible.

Real-World Performance: My Most Memorable Experiences

To really understand what makes the Skytour special, let me share a few specific experiences where this jacket proved its worth:

The Unexpected Storm

Last March, during what was forecast to be a bluebird day in the Tetons, our group watched as dark clouds rapidly built over the western ridgeline. Within 30 minutes, we were engulfed in a spring storm that brought driving sleet and gusty winds. While rapidly transitioning from ascent to descent mode, I kept the Skytour on despite the high-output activity of breaking trail. The breathability meant I stayed comfortable during the intense work, while the waterproofing kept the increasingly heavy precipitation at bay for the two-hour descent back to the trailhead.

The Four-Season Day

During a June ski mountaineering trip, we experienced what locals call “Colorado weather”—sunshine, rain, snow, and wind, all within the same day. The Skytour adapted to each condition admirably. During the sunny approach, the pit zips allowed enough ventilation to prevent overheating. When afternoon clouds brought a mix of rain and graupel, the hood and waterproof membrane kept me dry. As temperatures dropped near the summit, the shell effectively blocked wind while my insulating mid-layers provided warmth.

The Deep Powder Day

After an overnight storm deposited 18 inches of fresh snow in the backcountry, the Skytour’s powder-specific features proved their worth. The powder skirt prevented snow intrusion during multiple face-shots (and a couple of tomahawks), while the helmet-compatible hood kept snow from finding its way down my neck during particularly deep turns. Despite the high-energy output of powder skiing, the breathability prevented the clammy feeling often experienced in less breathable shells.

The Verdict: Is the Skytour Ascentshell Worth It?

After extensive use across varied conditions and activities, I can confidently say that the Outdoor Research Skytour Ascentshell Jacket represents one of the best values in technical mountain shells available today.

Its standout qualities include:

• Exceptional breathability during high-output activities
• Reliable weather protection for most alpine conditions
• Thoughtful feature set specifically designed for backcountry users
• Durable construction that withstands the rigors of mountain travel
• Reasonable price point compared to comparable technical shells

The jacket isn’t without limitations. In truly torrential, sustained precipitation, you might find slightly better performance from premium GORE-TEX Pro shells. And like all waterproof-breathable garments, it still requires occasional DWR renewal to maintain optimal performance.

However, for the vast majority of backcountry enthusiasts—whether your passion is ski touring, split boarding, alpine climbing, or general mountaineering—the Skytour Ascentshell offers a compelling combination of performance, durability, and value that few competitors can match.

Final Thoughts: The Evolution of Mountain Shells

What impresses me most about the Skytour Ascentshell is how it represents the evolution of mountain shell technology. Not long ago, we faced a stark choice between breathable jackets that wouldn’t keep us dry or waterproof jackets that felt like wearing a plastic bag. The Skytour, with its air-permeable Ascentshell membrane, demonstrates how far we’ve come in bridging that divide.

For those who spend significant time in the backcountry, the value of a shell that actually works with your body rather than against it cannot be overstated. The ability to maintain comfort across changing conditions and activity levels means less time adjusting layers and more time focusing on the mountain experience itself.

Whether you’re a dedicated backcountry enthusiast or someone looking to invest in their first serious mountain shell, the Outdoor Research Skytour Ascentshell deserves serious consideration. It has earned its place as my go-to shell for alpine adventures, and I suspect it would do the same for many others seeking the elusive balance of protection, comfort, and performance in the mountains.

Remember, the perfect shell isn’t the one with the most features or the highest price tag—it’s the one that disappears from your awareness during your adventures, protecting you without distraction. By that standard, the Skytour Ascentshell is very nearly perfect.
