Our Take:
4.3/5

Mountain Hardwear isn’t widely known for its hiking pants, but the Chockstone Alpine Light ($145) left a strong impression in testing. Its stretchy, midweight softshell construction is tough, protective, and quite comfortable. We also liked the fit—it’s technical without feeling overly slim or restrictive. True to its name, the Alpine Light is too thick and warm for balmy conditions at lower elevations, but the pant is an excellent pairing for big days exploring in cold and cool conditions.

Pros

Softshell material boosts warmth and weather resistance compared to your standard hiking pants.
The built-in belt is more high-end and easy to use than a drawstring.
Thoughtful features include cinches at the cuffs and three zippered pockets.
Stretch-woven nylon offers great freedom of movement.

Cons

Too warm for temperatures above about 60 degrees.
Pricier than standard hiking pants.

The Mountain Hardwear Chockstone Alpine Light’s stretch-woven nylon softshell fabric makes for a highly comfortable hiking pant, well-suited to the high-stepping demands of rock climbing and general outdoor wear. Whether lounging at home or hiking my favorite trails, the word that best describes these pants is simply: “Comfy.” The nylon/elastane blend provides excellent stretch and freedom of movement, whether squatting, pedaling, or sitting cross-legged on a break. I even wore them on a mountain biking photoshoot—chasing bikers, kneeling on rocks, and riding singletrack—and they never missed a beat.


That said, I did run into one comfort issue. On an overnight up Washington’s Ruth Mountain, the Mountain Hardwear Chockstone Alpine Light Pants performed well overall, but on the descent back to the valley, I got sweaty, and the inner seams began to chafe noticeably. Thankfully, I made it back to the car just in time, but with a few more miles, things could’ve gotten uncomfortable fast. I cover breathability in more detail below, but consider yourself warned: these pants can run warm.

Built with rock climbing in mind, the pant utilizes Mountain Hardwear’s Chockstone LT fabric, a nylon/elastane double-weave softshell blend that adds a layer of toughness. In many ways, it’s reminiscent of the thickness and all-around burly feel of Arc’teryx’s popular midweight Gamma. After more than two months of hard use, the Chockstone Alpine Light pants have proven to be impressively durable. I’ve hiked, biked, traveled, and even worn them to family dinners, and they’ve held up without issue. My only minor gripe is that one of the small zipper pull cords detached in the dryer, but otherwise, the zippers, seams, and fabric have all remained intact and in great shape.

I consider MH’s Chockstone to be a cool weather pant, and breathability is one of its chief downsides. Unlike a comparable pant like Fjallraven’s Keb Agile, there’s no built-in vents to dump heat when the going gets warm. For the most part, I’d keep these pants in the 40s to low 60s range. As mentioned above, I experienced some chafing and discomfort due to sweat on the descent into the warm valley after one overnight while wearing these pants. For hot summer days, I’d look elsewhere. But for cloudy skies and cold to moderate temps, these pants excel.

The Chockstone’s softshell construction gives it a clear edge in weather protection over standard hiking pants. The biggest advantage is wind resistance—the woven fabric noticeably cuts the chill compared to typical nylon blends, making it a great choice for exposed ridgelines or breezy alpine terrain. There’s also a DWR coating that effectively sheds light moisture, offering decent protection in passing showers or dewy morning starts. As with any non-waterproof design, expect to get soaked in a downpour, but the good news is I found the pants dry quickly


Among the hiking pants we’ve tested, the Chockstone slots just below true alpine-ready options like Outdoor Research’s Cirque Lite but holds its own against midweight softshells like the Arc’teryx Gamma. And compared to standard hiking pants like the Prana Stretch Zion or Patagonia’s Quandary, the boost in wind and warmth is substantial—especially when you’re lingering around camp or starting a chilly early-morning climb.

Pockets
The Chockstone Alpine Light comes well-equipped with features that strike a nice balance between everyday utility and technical function. Starting with storage, you get three zippered pockets—two at the hips in the standard position and a third on the thigh. The thigh pocket includes a built-in tether that’s a nice touch for climbing, allowing you to secure your phone or small essentials while wearing a harness. It’s not as useful for casual wear, but in more technical environments, it’s a smart addition.


Waistband, Cuffs, & Other Features

Up top, the integrated belt makes dialing in the fit easy without needing to pack extra accessories. While the belt can gradually loosen over time, it’s quick and easy to retighten on the go. At the ankle, a cinch cord allows you to secure the cuffs over shoes or boots, or pull them up and out of the way—handy for stream crossings, lounging in sandals, or keeping things tidy under gaiters. All in all, the Chockstone’s feature set adds meaningful utility without weighing you down.

Longevity

Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.

The Mountain Hardwear Chockstone Alpine Light strikes a great balance in fit—what I’d call a true “Goldilocks” pant. While Mountain Hardwear labels the fit as “trim,” it wears more like a regular cut in practice: not overly slim or restrictive, but not baggy either. Compared to more technical, form-fitting options like Fjallraven’s Keb Agile, the Chockstone has a bit more room to move without feeling loose or sloppy.


Sizing is inclusive, with five waist options from S to XXL and three inseam lengths (short, regular, and long), accommodating waists from 29 to 43 inches. I’d prefer to see smaller increments between waist sizes, as you’ll find with a pant specialist like Kuhl. But on my frame, the fit felt just right: plenty of mobility without excess fabric getting in the way.

Arc'teryx Gamma ($200): The Category Leader
The big question to answer here is: Is the Gamma really as good as its price suggests? The pant is similar to the Chockstone Light, with a midweight softshell fabric that steps up the warmth quotient from a standard hiking pant and offers excellent stretch and weather resistance. Feature-wise, the Gamma also has two zippered hand pockets, a zippered thigh pocket, a built-in belt, and hem cinches with grommets (attach a small cord to these to secure the pants under your boots—a great feature for traveling in snow). The Gamma gets the edge in weight and packability. And the Gamma excels at the little things: Its pockets offer a sleeker look, the fit is a bit more refined, and Arc’teryx’s build quality generally offers a certain je ne sais quoi that makes you feel like you’re getting your money’s worth. To learn more, check out our Arc'teryx Gamma review.


Black Diamond Alpine Light ($149): A Step Down in Value
The Black Diamond Alpine Light is a step down in almost every way from the Chockstone Alpine Light. The most obvious difference is the fabric weight: The Alpine Light uses a lighter-weight material best suited for mild weather pursuits and offers less wind and water resistance than the Chockstone. The other big differentiator is the pants’ build qualities. The Mountain Hardwear impressed us with its premium construction, while the BD leaves a lot to be desired: the webbing belt has a tendency to roll, we had sections of the stitching start to unravel just a few weeks into use, and the material is much more prone to ripping. If you don’t mind the added insulation and weather protection, the Chockstone offers much better quality for a similar price. To learn more, see our review of the Alpine Light.

4.3/5

Though a climbing pant by design, the Chockstone Alpine Light is a wildly functional hiking pant for cooler weather. The above-average price is well-spent for the built-in belt and zippered pockets.

Built for climbers and adopted by hikers and backpackers looking for a durable and protective pant for alpine environments, the Gamma is about as premium as it gets. The fit is exceptional, and all the details are thoughtfully sorted. Warmth and price should be your only hesitations.

The Alpine Light offers a Goldilocks combination of fabric weight and stretch for fair-weather hikers. However, the pant lacks a refined finish, and the material is not particularly durable. For the price, it’s not a long-lasting option.

Is the Chockstone Alpine Light for You?

While the Mountain Hardwear Chockstone Alpine Lights are purpose-built for rock climbing, they shine across a wide range of outdoor activities. I’ve worn them for everything from backpacking and mountain biking to family dinners and flights—they’re just that versatile. These hiking pants do run a bit warm for low-elevation summer adventures, but otherwise, there’s little to nitpick. The Chockstones are comfortable, protective, durable, and stylish—a solid choice for most outings in cold to mild weather.
