You are active all winter long, whether on the hiking trails, on the ski slopes, or even in the backcountry, and you are looking for snow pants that will allow you to stay both warm and dry? Here’s everything you need to know about the most important features of snow pants to find the right ones for you. Follow the guide!
In this article, you will learn more about:
What does “insulated pants” mean? How can you avoid sweating while ski touring or snowshoeing? Is water-repellent fabric the same as waterproof fabric? If all these questions are running through your mind when shopping for snow pants, it’s completely normal. Buying technical clothing for winter is not as easy as it sounds. Understanding the importance of these three key elements will render you able to choose:
When we say that a garment is insulated, it means that it has thermal insulation—in the form of a synthetic layer or down, for example—, which provides a warm lining to your body to block out the outside temperature.
Even though legs are less sensitive to cold than the rest of the body, it can still be important to protect your thighs and buttocks from the bites of winter. For this, there are insulated, partially insulated or non-insulated snow pants. Your choice will mainly depend on the intensity of your activity and your tolerance to cold and heat.
Activities that involve periods of stillness (such as ice fishing or downhill skiing at lift time) require a good layer of insulation. In the context of intense sports such as cross-country skiing or ski touring, which make you sweat easily, it can be interesting, on the other hand, to opt for non-insulated pants.
In any case, remember to pick a size large enough to possibly wear an additional underlayer, such as merino wool leggings if you are chilly or going out in extremely cold weather.
There’s nothing worse than feeling cold and wet after just a few hours of playing outside in the snow. For this reason, it is important to choose waterproof pants. Unlike water-repellent fabrics (on which water drops or snowflakes fall in beads and then penetrate through the fabric after a few minutes), waterproof membranes (such as Gore-Tex and its derivatives) completely repel moisture. To find out the degree of impermeability of a garment, check the label for a measurement expressed in Schmerber (10,000 Schmerber = 10,000 mm of water, i.e. the equivalent of the resistance of the fabric to a 10-metre water column). The higher the number, the more waterproof the fabric. For example, all Gore-Tex pants have a Schmerber index of 28,000 mmr. It is also important to check if the seams are well sealed and if the zippers have an inner waterproof strip to prevent any passage of cold air through these thin gaps.

Last important criterion in choosing your snow pants: breathability. This is especially true for high-intensity activities like cross-country skiing or ski touring. Indeed, if your pants keep you warm and protected from external humidity without sufficiently wicking away perspiration, it is on the inside that you risk overheating and being soaked. Two elements are therefore essential: the breathability of the fabric and the ventilation system of the pants.
Once again, Gore-Tex type membranes, called waterproof-breathable, are ideal. If you look at them under a microscope, you will see an incredible number of pores per square centimetre. Each of these tiny holes is 20,000 times smaller than a water droplet, which keeps moisture out, while being 700 times larger than a water vapour molecule, which lets your sweat out.
In addition, many models of ski touring pants now have long zippers on the side of the legs. This allows you to ventilate your lower body during a ski touring ascent, for example.
As you will have understood, it is the type of activity you indulge in that will determine the criteria which are the most important when choosing snow pants. To make things easier, discover here how important insulation (warmth), waterproofing and breathability are for each type of winter activity.
Skiing and snowboarding:
When alpine skiing, you sweat very little (even less from your legs) and your body has relatively little contact with the snow. On the other hand, you spend a lot of time immobile in the queue and on the seats of the ski lifts. As a result, it is necessary to look for insulated (and therefore warm) and comfortable pants.
When snowboarding, you have more contact with the snow, when you sit down to take a break or close your bindings. It may be important to opt for pants with reinforced insulation and waterproofing in the buttocks and knees. Also consider trousers in the form of overalls (also called bibs), which prevent snow from entering in the event of a fall.
Walking and snowshoeing:
During a walk or a winter hike, it is important to wear comfortable and breathable pants. Indeed, walking in the snow or snowshoeing, especially when there is a variation in altitude, is a cardio exercise that makes you sweat easily. Avoid pants that are too insulated or too thick and favour the multilayer system with the addition of leggings in cold weather.
Some materials can also be noisy with every step. Remember to walk a few metres in store to test the different fabrics.
For hiking, products from Mountain Hardwear are a must.
As mentioned earlier, ski touring is an intense sport that requires great versatility in your clothing. Look for pants that are non-insulated and breathable, with wide openings on the side of the legs if possible, to open when climbing with skins. Waterproofing is also an important criterion if you plan to descend in fresh powder.
Rab, well known in the ski community, offers several very breathable and high-performance pants for ski touring enthusiasts.Backcountry Ski Touring Clothing
Widely acclaimed by cross-country skiing enthusiasts, close-fitting pants such as leggings are to be preferred. They are much more aerodynamic than other snow pants and they are very breathable. If you are Nordic skiing and you are likely to be in more contact with the snow (lower legs especially), look for models that are more waterproof or with windproof material on the front of the thighs for severely cold days.
This is also the case for fatbike enthusiasts. Avoid insulated pants or pants that are too wide at the bottom of the legs to increase your comfort when pedalling.Cross-country Skiing Clothing
If you are looking for versatile pants for occasional and not too intense activities such as ice fishing, skating or even sledding, aim for warm and waterproof models. They will guarantee you maximum comfort for all your winter outings.
Now you know everything about snow pants, so you are ready to have fun outside all winter long!
