The Top Alpine Pants: How To Choose
Finding the ideal mountaineering pants starts with knowing what to look for as you shop. So, here are some of the key things to keep in mind when searching for your next alpine climbing pants.

Soft Shell vs Hard Shell
When shopping for mountaineering pants, you’ll first have to decide if you want a softshell or hardshell model.
The primary difference between softshell and hardshell trousers is whether or not they’re waterproof. While hardshell models are meant to be fully waterproof, softshell trousers are generally just water-resistant.
This means that hardshells are ideal in situations where you can reasonably expect a lot of rain or snow. While this hardshell fabric comes with a decrease in breathability, it is designed to keep you dry at all costs.
Alternatively, softshell trousers are the gold standard when it comes to breathability, stretch, and comfort. They might not be able to block out all water and snow, but they provide some wind-resistance and excellent freedom of motion as you climb.

Moral of the story? If lots of rain and snow are in the forecast, hardshells might be the better option. Otherwise, most folks find that a softshell model is more than sufficient.
No one likes to invest in a quality pair of mountaineering trousers only to have them fall apart after a few climbs. Therefore, the durability of your potential trousers should be at the forefront of your mind as you shop.
When it comes to alpine trousers, there are 2 key durability-related features to look out for. These include:
- Reinforced Instep Patches: Climbing with crampons is a solid way to put holes in your pant legs. This being so, many gear manufacturers, like Mountain Hardwear, Arc’teryx, and The North Face, place reinforced instep patches on pant legs.
These patches offer an extra layer of protection against sharp crampon points. That way, you can climb without fear of damaging your trousers.
- Thick Fabrics: Because climbing and mountaineering are rough-and-tumble pursuits, all alpine trousers need to be relatively abrasion-resistant.
To accomplish this, many manufacturers opt to use thicker fabrics (usually more than 60D) in their alpine trousers. While these fabrics might result in a decrease in breathability, most folks won’t mind if it means added durability in the mountains.
Fit, Comfort & Range of Motion
As with any piece of outdoor clothing, the fit and comfort of your mountaineering trousers are critical considerations. Comfort is unique to every individual, of course. However, there are some comfort-focused features of alpine trousers that you should know about as you shop.

In fact, comfort and range of motion in trousers boil down to 3 key features: stretchy fabrics, knee articulation, and crotch gussets. Here’s what you need to know:
If there’s one mountaineering pants feature that has a direct impact on your comfort in the alpine, it’s the stretch of the trouser fabric itself.
Fabrics that don’t stretch simply can’t provide the range of motion you need to climb through tricky terrain. So, looking for trousers with a high percentage of spandex or lycra in their fabric composition is essential.
Many mountaineering trousers have something called “articulated knees.” This might sound complicated, but articulation in trousers simply refers to the shape of the pant leg.
Trousers without articulated patterning will have straight legs, which can reduce your range of motion as you climb. Meanwhile, models with articulated knees are designed to mimic the natural shape of your leg. As a result, they provide unrestricted movement in all types of activity and terrain.
A crotch gusset is a little-known trouser feature that has a major impact on your climbing experience.
Essentially, a crotch gusset is a small, diamond-shaped piece of fabric that connects each pant leg. This diamond-shaped fabric eliminates the need to have a single point in the middle of the trouser crotch where four seams connect.
By doing so, the crotch gusset allows for unparalleled range of motion, durability, and comfort as you climb.
When you’re in the mountains, having a quality set of pockets on your trousers can have a major impact on your climbing experience. While a small, inconveniently placed pocket won’t get you very far, having a quality thigh or hand pocket can make a difference.
So, as you shop for trousers, pay close attention to the number, size, and layout of each model’s pockets.
In particular, you’ll look for a model that has zippered hand pockets and the occasional thigh pouch for gear security as you limb.
Furthermore, if you expect to wear a harness during your adventures, trousers with harness-compatible pockets can be a major asset. Otherwise, your gear will be uncomfortably trapped between your leg and your harness if you take a fall—ouch!

Decidedly durable, the Simul Alpine are made with 100% polyester stretch double weave fabric with four-way stretch. As an added bonus, these trousers are made with materials that are both bluesign-approved and Fair Trade Certified sewn.
Plus, the Simul Alpine features a DWR finish to make them water-resistant, and articulated patterning for comfort. These trousers are even designed to fit under a harness for alpine or ice climbing, thanks to their OppoSet adjustable integrated belt.

- DWR finish for use in all weather conditions
- Integrated waist belt for an improved fit
- Harness-compatible design
- Lack of reinforced insteps is a durability concern

Outdoor Research Cirque II
Best for Cold Weather Climbing
For cold-weather adventures in the alpine, the Outdoor Research Cirque II is your go-to pair of mountain hiking pants.
Engineered out of a highly breathable 90D nylon/polyester stretch fabric, the Cirque II is perfect for use in truly frigid temps. It’s also treated with DWR to help shed light rain and snow as you climb.
Where the Cirque II really shine, however, is in terms of their durability and functionality. In addition to the trousers’ harness-compatible waist-belt and pockets, it also features a set of rugged scuff guards on each pant leg. As a result, these comfortable pants are designed to last and perform, even after years of use in the mountains.
The downside to the Cirque II, though, is that their thicker weight makes them less-than-ideal for warmer temperatures. However, if your goal is to have a reliable set of winter climbing pants, the Cirque II deserve a place very near the top of your shortlist.
- Warm enough for wintery conditions
- Highly weather-resistant
- Reinforced insteps for added durability
- Harness-compatible waist
- Too thick and heavy for summer use
Bottom-Line: The Outdoor Research Cirque II are an amazing set of softshell trousers that offer great performance in cold temperatures.
Black Diamond Dawn Patrol
Best for Ski Mountaineering
Whether you like to hike, climb, or ski, the Black Diamond Dawn Patrol is a fully-featured pair of mountaineering pants that’s ready to provide the performance you need on any expedition.
Crafted specifically with ski mountaineers in mind, the Dawn Patrol is made from a burly woven fabric with four-way stretch for enhanced comfort in the backcountry. It also features a DWR treatment for water and wind-resistance, and it boasts snow gaiters to keep your boots dry at all times.
The Dawn Patrol softshell pants use built-in vents on each pant leg for increased breathability. What’s more, they also have reinforced instep patches and plenty of zippered pockets to help you stay organized on the go.
The primary downside to this model, though, is that they’re a bit pricey and they’re fairly heavy for summertime use. But, for a cold-weather softshell pant for men like this, the Dawn Patrol is a fantastic choice.

It’s worth mentioning that the Kinetic Alpine’s weight savings come at the cost of some durability and functionality.

The downside? The Beta SV aren’t exactly budget-friendly. Plus, they don’t have many pockets, which might be a bummer for some climbers who like to keep a few bits and bobs easily accessible. If you need fully waterproof mountaineering pants, though, the Beta SV are worthy of your consideration.
