Best Mountaineering Pants: Finding The Right Pair for Your Next Big Ascent

For any mountaineering adventure it’s essential to have a pair of pants that you can throw on for any climb and feel comfortable in during any ascent or descent. Softshells are some of the best mountaineering pants out there because of their weather resistance, breathability and flexibility.

Softshells are ideal for mountaineering expeditions but they’re useful for any climber, hiker, trekker, and adventurer of the outdoors.

Softshell pants are designed for thermal regulation and maximum performance so you don’t need to wear three or four different layers. They’re versatile and comfortable in a wide range of weather conditions and temperatures, making them a reliable mid-layer or stand-alone outer layer.

Having less layers helps you reduce weight, cost and backpack bulk on any outdoor excursion. Wearing less layers also reduces the amount of resistance to your movements.

Convinced that you need a pair of softshells for your next outdoor climb? Keep reading to learn about the differences between hardshells and softshells and important features to consider when looking to invest in a pair of mountaineering pants. This article also includes product reviews of the best softshell pants on the market for both men and women.

Hardshells vs. Softshells

First off, it’s important to address the differences between hardshell and softshell clothing:

Hardshell fabric is designed to be your outermost layer for maximum weather protection. Hardshells are windproof, waterproof, mostly breathable and offer full storm protection. They’re intended for high performance wear and for prolonged, intensive use in the outdoors.

Hardshells are made up of a woven fabric laminated to micro-porous coatings or breathable waterproof membranes. They’re breathable to an extent, but for any high heart rate activity, the inside of your garment is bound to feel damp and clammy with condensation and perspiration.

Softshell fabric on the other hand is intended to be less rigid than hardshell fabrics and can be used as a protective mid layer or outer layer. Softshells are water repellent, air permeable, breathable and stretchy to ensure mobility and flexibility.

They’re designed for outdoor aerobic activities with exposure to dynamic weather conditions such as climbing and mountaineering. Although softshells are generally not waterproof, their windproofing aspect is key to warmth against the elements.

Their weather resistance and breathability take priority over waterproofness, but softshells can shed light rain and snow and dry fairly quickly. They’re also meant to be abrasion resistant to stand up against the wear and tear of rough outdoor terrain.

Overall, softshells are intended to keep the user warm, dry and able to move freely. The next section outlines some of the features to consider when looking to invest in softshell mountaineering pants.

Important Features to Consider


  • Stretch Wovens are considered one of the most lightweight softshell fabrics on the market. The fabric was designed to be wind and water resistant and highly breathable for any high aerobic activity. Stretch wovens became popularized by Schoeller who have come out with a single layer construction and a double weave.
  • Laminated Stretch is a combination of stretch woven nylon, a stretch poly-urethane coating or membrane, and an insulating layer such as a fleece. Having the poly-urethane layer enhances the windproofness and water repellency of the pant. Not only that, but it adds a layer of insulation, making it ideal for colder temperatures and higher elevations.
  • Encapsulation is the inclusion of a barrier film placed between the fibre bundles. The film is an ultra-thin polymer that is both durable and breathable. Having the film inside the fabric also enhances thermal efficiency and water repellency even after repeated washes.

Weather Resistance

When looking to invest in a pair of softshell pants it’s important to look at the fabric’s weather resistance based on its water repellency and windproofness.

Water repellency is how well a material can shed water. Softshells are generally made with water resistant materials that have a high degree of wicking power and are also quick drying. You’ll also find softshells with water repellant coatings that ensure both water resistance and breathability.

It’s uncommon to find softshells that are 100% waterproof because waterproofness often means that its breathability has been compromised.

Windproofness is important for softshells because it helps with thermal regulation. Having one layer of clothing that can protect you against the wind takes away the need to wear three or four different layers. Material that is both windproof and breathable helps keep you insulated but also efficiently sheds away excess heat created by high aerobic activities.


Breathability is one of the main factors that sets softshells apart from hardshells. The idea is that softshells will be used for high aerobic activities, so the best materials are those that can easily breathe when a lot of energy is exerted.

Hardshells tend to leave you feeling clammy and uncomfortable after a good sweat because they are not as air permeable.

Softshells on the other hand are not meant to keep moisture in; they’re meant to breathe and keep you comfortable on any climb.


Some mountaineering pants have reinforcements on the knees, seat, and ankles. These areas of the body have a higher risk of abrasion while climbing. Having reinforcements on these parts of the pants can ensure their durability and longevity. But even without reinforcements, there are a number of softshell materials that are made to be abrasion resistant.

Abrasion resistance is an important feature to have for climbing pants to ensure they can hold up to rock faces and any other rough terrain.


Weight is an important consideration for any outdoor excursion, especially for longer expeditions where you’ll be carrying your gear for an extended amount of time and distance. You can find softshell pants in a variety of weights, depending on the fabrics used and any added features.

Generally, if the pants have extra fabric for abrasion resistance or an extra layer of insulation they’ll be heavier than ones without these added features.


Another feature you might find in a softshell pant is its ability to convert into a short or capri. This feature helps with thermal regulation for hot summer days. Having pant legs that can be zipped off or rolled up offer versatility, making the softshell pant also great for hiking and trekking.

Now that you’re familiar with the important features to look for in a softshell mountaineering pant, it’s time to take a look at some of the most popular softshells on the market.

Final Words

What’s great about investing in a pair of softshell pants is that they’re designed to be an all-in-one layer for weather resistance and breathability. They can be used as a mid-layer for colder weather or when the weather permits, softshells can be your outer layer instead of a hardshell.

Not only are they versatile as a mountaineering pant, but they can be used for a number of outdoor activities such as hiking, backpacking, skiing and snowboarding. Be sure to research and assess different pant features and styles to find the pair that will be perfect for you and your next outdoor adventure.

Though I do mainly wear them in the great outdoors, I have recently started wearing them at work too. They look smart enough without easily being identifiable as hiking pants. They’re nice and lightweight with a fair amount of stretch. The breathability of the pants and the addition of a side entry thigh pocket all add up to a well thought out pair of pants. I’d highly recommend!

  4. Most of my buddies, including me love the Prana Stretch and I say, it’s not only for good for mountaineering. In fact, they’re great for everyday use, too. It’s very comfortable and the breathable fabric is tops!

  5. I have been planning to buy mountaineering pants for the longest time, but it is hard to choose what brand to get. Thank you for your list Mark because I was able to narrow down my choices. I am thinking of buying either Mountain Hardwear’s Desna Alpen or 66oNorth Snaefell.
