In this article, you will find all the key features to consider when choosing the right ski trousers. Ski trousers are designed to keep you warm and, above all, dry throughout your day on the mountain. In direct contact with the snow, they must be waterproof and breathable while providing comfort through thermal insulation. Softshell trousers can be an excellent option if you are looking for comfort or greater freedom of movement. This two-dimensional weaving technique delivers thermal insulation and wind resistance while maintaining flexibility and high breathability.

Choosing waterproof and breathable ski trousers
Waterproofing is measured in mm Schmerber: the higher the number, the more effective the membrane. Go for a rating of 10,000 mm or above to stay dry in all conditions. The trousers must also have fully taped seams.
Breathability is essential: you start to feel cold when you are wet. Sweat must be evacuated efficiently. Breathability is measured in grs/m²/24H — the higher the figure, the better the moisture transfer. Aim for a rating of 8,000 grs/m²/24H or above.

Optimal insulation for ski trousers
Thinsulate™ Insulation is used in the lining of ski trousers. Made from very dense synthetic fibres, it delivers superior thermal insulation.
The PrimaLoft® technology, featured across many of our products, delivers lightweight, breathable and warm garments. PrimaLoft® is a lightweight synthetic fabric that stays warm, water-repellent and fully technical even when wet.
The small details that make a big difference when choosing your ski trousers
Ventilation zips
To regulate airflow during physical effort, look for ski trousers fitted with ventilation zips. Positioned along the outer thigh, they let you stay at the right temperature throughout the day.
Integrated snow gaiters
Integrated snow gaiters are built into the lower leg of your trousers. Specifically designed to prevent snow from getting in — particularly when skiing off-piste in powder — they keep you dry and comfortable all day long.
Reinforcements
For beginners and freeriders alike, strategic reinforcements at the seat, knees or lower leg can make a real difference in the event of a fall.
Safety beacons
Off-piste enthusiasts can add an extra layer of safety by choosing ski trousers fitted with a locating beacon such as RECCO. These beacons are sewn directly into the garment. They reflect the signal from rescue transponders on the mountain, allowing you to be located more quickly if you are caught in an avalanche.

Matching your ski trousers to your discipline
For ALPINE SKIING
If you spend your days on the pistes, you need trousers that are both waterproof and breathable. During this type of skiing, you will experience cold spells — particularly on chairlifts. A warm, well-fitted pair of trousers is therefore the way to go.
For FREERIDE SKIING
You need trousers that are seriously waterproof and can handle full days in the snow. A durable fabric with knee reinforcements is essential to withstand abrasion from the terrain (roots, branches, rocks, etc.). In terms of fit, go for a looser cut to give you maximum freedom of movement on your skis. For waterproofing, aim for a rating of at least 20,000 mm. And if safety is a priority when skiing off-piste, look for trousers equipped with a RECCO locating beacon.
For SKI TOURING
Ski touring demands serious effort on the ascent and a little less on the way down. Your trousers therefore need to combine solid waterproofing with excellent breathability — but without too much insulation. During the climb, you do not want to overheat. A windproof layer protects you from wind and the elements, especially on the descent. External venting openings are also recommended for ski touring, as they allow for better ventilation.
For SNOWBOARDING
At the start, you will spend a fair amount of time on your backside and knees. You need trousers reinforced in those areas to stay dry. And of course, they must be warm and waterproof. For powder lovers, integrated gaiters are a real bonus — they keep snow out after a fall, so you stay warm throughout the day.
For CROSS-COUNTRY SKIING
Cross-country skiing is an endurance sport with significant fluctuations in body temperature. To avoid overheating or getting cold while maintaining freedom of movement, opt for tights — they keep you warm at the start of your session and then efficiently wick away sweat during effort.
For sizing, beyond standard men's and women's sizes, some brands offer different leg lengths to suit your height.
