Reviews - The Best Pants for Mountaineering

Outdoor Research Cirque

View Women's Version
  • Closure: Zipper/Button/Adjustable Velcro Waist
  • Type of Waterproofing: Water Resistant
  • Shell: Softshell
  • Bootlace Hooks (to keep pant leg in place)
  • Movement Mirroring Stretching (for a solid fit and all day comfort)
  • Reinforced Scuff Guard (to protect against crampon snags)


Outdoor Research is well known for their clothing and their Cirque pant has been a top mountaineering workhorse for years. The low-profile waist includes side velcro tabs for a perfect fit around the waist and will easily fit under a climbing harness without bunching. The zipper pockets are perfect for storing the essentials like maps, snacks, and headlamps without having to worry about them falling out. All zippers are finished with a water repellent, so you won’t experience leakage even if you encounter foul weather.

The pant bottoms are designed with a scuff guard for those technical times you have to put on the crampons and could get a snag. The bottoms also include metal bootlace hooks that will attach to your boot laces to keep your pants in place. Plus, the drawcord cuffs and zipper closures prevent the pants from walking up your boots and getting any snow pile-up, eliminating the need for a gaiter.

Arc’teryx Gamma AR

  • Closure: Zipper/Snap with Waist Belt
  • Type of Waterproofing: Water Resistant
  • Shell: Softshell
  • Burly Double Weave Material (eliminating moisture and wind)
  • Gusseted Crotch And Articulated Patterning (for full range of motion)
  • Trim Fit (to fit under a hardshell)


The Gamma AR pant by Arc’teryx is on the higher end of cost, but with that comes high performance. This wind and water resistant pant is made from a burly double weave material that not only provides protection from the elements, but also provides stretch, warmth, and resistance to abrasion from any rocks and ice you may encounter on the mountain.

The low-profile waist includes a belt for a secure cinch that will fit under a climbing harness or pack. Pockets on this pant are strategically placed with two hand zipper pockets below the harness line and a zipper thigh pocket for quick stashing. Bootlace hooks are designed to attach to bootlaces and the adjustable cuffs at the bottom of each leg eliminates the need for gaiters.

Patagonia Simul Alpine

  • Closure: Zipper Fly/Button/Draw Band Waist
  • Type of Waterproofing: Water Resistant
  • Shell: Softshell
  • Tie-Down Loops For Boots
  • Lightweight for Cooling And Less Bulk
  • Gusseted Crotch (for full range of motion)


This Patagonia pant offers zippered hand and thigh pockets that sit outside the climbing harness area and help make this a good choice for more technical ascents. The adjustable draw band waist ensures a snug fit without needing a belt and cuts down on bulk. 

The adjustable cuff with tie-down loops gives these pants the ability to be used with heavy duty alpine boots. While on the lighter side of mountaineering pants, they are durable and reliable, allowing them to be used on training hikes where you want pants that are light and cool, but still able to keep you dry during mild snow encounters.

Outdoor Research Skyward II

View Women's Version
  • Closure: Zipper Fly/Snap/Belt Loops
  • Type of Waterproofing: Waterproof
  • Shell: Softshell
  • Built-In Inside Gaiter (to prevent water, snow, and dirt from entering your boots without having to carry additional gear)
  • Built-In Avalanche Beacon Clip (to clip avalanche beacon to while in the backcountry)
  • Zippered Outer Thigh Vents (to help ventilate and keep you cool)


A soft shell that acts like a hard shell, this Outdoor Research Pant offers protection for any weather – wind, rain, ice, and snow. While they are waterproof, these pants are designed with Outdoor Research’s AscentShell, which allows for breathability while keeping you dry. Further excess heat during performance can be vented through the zipper thighs.

This pant goes to the next level with a gaiter built-in, giving you full snow protection without having to carry any extra gear. And because these pants may lead you to the snowier side of mountaineering, they even have a built-in avalanche beacon clip to keep you extra safe in the backcountry.

Mountain Equipment Ibex

  • Closure: Zipper Fly and Snap
  • Type of Waterproofing: Water Resistant
  • Shell: Softshell
  • Micro-Fleece Lined Waist (to keep you warm/comfortable)
  • Pre-Shaped Knee For Natural Articulation
  • Integrated Belt


The Mountain Equipment Ibex pant is an ideal pant to get you started into mountaineering on those long, cool day treks. These pants are a lighter weight option with a waist that’s lined with micro-fleece, so wearing a pack all day is sure to be a comfortable experience. 

Although these pants excel for more mild mountaineering, they still include a few useful features for use in the colder mountain weather. The pant cuffs are equipped with ankle zips and a gusset panel (to allow for more stretch), both of which help to accommodate mountain boots so that these pants can be used in the snow as well. And because they are on the lower end of the cost spectrum, they are an all around good pant to have in your arsenal.

Black Diamond Alpine

  • Closure: Zipper Fly and Snap
  • Type of Waterproofing: Water Resistant
  • Shell: Softshell
  • Built-in Waist Belt
  • 2-Way Zipper Fly (for men’s pants)
  • Four-Way Stretch Fabric (for all movement)


The Black Diamond Alpine pant offers just the right amount of coverage to keep you warm on those chilly fall and spring expeditions. Extremely durable, this pant is also breathable and provides the stretch needed to handle any motion on the mountain.

Offering both an adjustable belt loop and drawcord cuff at the bottom of the pant, you will have a secure fit in these pants. The zippered hand pockets will protect your valuables on the route, while the exposed thigh pocket is functional and can also be used as a vent to keep you cool if the day heats up.

Rab Kinetic Alpine

  • Closure: Zipper Fly/Snap/Drawcord Waist
  • Type of Waterproofing: Waterproof
  • Shell: Softshell
  • Knee Articulation For Ease Of Movement
  • Knit Wicking Lining (to pull sweat away and keep you dry and cool)
  • Stuff Sack To Store Pants When Not In Use


RAB Kinetic pants offer a sweat wicking waterproof softshell with maximum stretching for any movement, making them a great pant for wet weather mountaineering. The zippered ankles allow this pant to be used with mountaineering boots and the webbing loop allows them to attach directly to the boot.

The drawstring waist of this pant provides a secure fit, so you won’t have to worry about them slipping down. This lightweight and packable pant also comes with a small stuff sack to condense them into your pack or clip to your harness when the weather improves.

If you’re new to mountaineering, you can expect to pay a bit more for a solid pair of pants than you would for hiking. But do not try to cut corners to save a few bucks! In the long run, having the appropriate pair of pants for your mountaineering adventure will make all the difference in whether or not you have a positive experience, especially if you encounter foul weather.



There are two shell types that you will see out there – hardshell and softshell. Many mountaineering pants today are making softshells that offer the same wind and water resistance as the hardshell, eliminating the need for two pairs of pants. While hardshells do a great job of keeping you dry in rain and snow, if you get your heartrate up and begin to sweat, they tend to keep that moisture in, which can lead to other issues. Read more about how to decide between hardshell vs. softshell mountaineering pants.



The same rules for hiking pants apply to mountaineering pants – cotton is rotten. Just like shirts, it is important to consider the materials and fabric types when selecting mountaineering pants. Choosing a fabric that is durable, but provides some stretch is just as important as choosing a breathable, but warm fabric.



Especially when looking at softshell pants, it is imperative to look at the weather ratings, particularly wind and water resistance. A pair of pants that is waterproof is impenetrable to water, but most softshells will absorb some water in order to provide breathability. In this case, the pants will be categorized as water resistant, meaning they can withstand a certain amount of moisture and not act like a sponge.

On day trips in more mild conditions, a water resistant pant will be all you need, but on longer days in colder and constantly wet conditions, a water resistant pant may stay damp. In these situations, having a softshell pant that breathes better than a hardshell will work, but you will also want a thin pair of hardshell pants to throw over top to prevent getting damp and cold.



Breathability is what sets apart hardshell and softshell pants. Because the material of hardshell is not penetrable, it will keep moisture in and can cause you to feel clammy and cold when your heart rate lowers, which can be extremely dangerous in the mountains. Softshells allow some air flow while still providing water and wind resistance, so even if you work up a sweat, the moisture can evaporate and you will not catch that chill when you slow your pace.





The bottom part of the pant that covers the top of the boot.


The cut of the pants and how they fit around the waist. Low profile waists leave less bulk around the waist for use with harnesses and backpacks.


Material that does not allow for any water to penetrate the material.


Material that is able to repel water, but not completely impenetrable to water.


Zippers on the outer thigh of the pant that start at the cuff and end at 7/8 or 3/4 of the way up the outer thigh to allow them to be added over top of softshell layers without the need to remove your boots.


A tab (usually on the front part of the pant cuff) that allows pants to be attached to the laces of boots.
