With winter setting in, there is no need to buy extra gear if you already own a quality technical jacket. Using your hiking jacket for skiing is entirely possible, provided you understand the different demands of walking versus snowsports.
Here is how to turn your trail gear into effective protection for the ski slopes.
Is your hiking jacket "Ski-Ready"?
Not all walking jackets are created equal when facing snow. To ski with complete peace of mind, your jacket must meet two crucial criteria.
First, high waterproof performance (ideally 20,000 mm Schmerber): unlike rain, snow stays on the fabric, melts under pressure (during a fall or on a wet chairlift), and will eventually penetrate an inadequate membrane.
Next, check the wind protection. On the slopes, wind is not just about the weather—it is generated by your speed. A jacket engineered with a protective membrane (Hardshell type) is essential to block freezing draughts and retain core body warmth.
Why do you feel colder skiing than hiking?
It is simple physics: the faster you go, the quicker your body loses heat. This is known as wind chill. When hiking, you walk at around 5 km/h. When skiing, you regularly descend at 40 to 50 km/h. At this speed, cold air strips away the thin layer of warm air naturally insulating your skin.
The result: if it is -5°C on the slopes and you are skiing at full speed, it can feel closer to -15°C. Your hiking jacket is often thinner than a padded ski jacket, so you need to pair it with a warmer thermal mid-layer (a thick fleece or thin down jacket) than you would normally wear.
Which technology to choose: Hardshell, Softshell or 3-in-1?
Not all hiking jackets offer the same level of comfort on skis:
- The Hardshell jacket: The best choice. Its protective membrane (such as Ultrashell) acts as a total barrier. Because it is non-insulated, it delivers maximum versatility: you control your own thermal layering depending on the weather.
- The Softshell jacket: Its high breathability makes it ideal for the uphill sections of ski touring. However, a softshell jacket is often not recommended for resort alpine skiing: it may let water in if you spend too long lying in the snow after a fall.
- The 3-in-1 jacket: The practical, all-in-one solution. It already integrates a removable insulating layer, making it the closest alternative to a traditional ski jacket.
Tips to make up for the lack of ski-specific features
If you use a waterproof hiking jacket rather than a dedicated ski jacket, you may miss a few practical features. Here is how to compensate:
- No powder skirt: To stop snow getting up your back if you fall, wear ski trousers with braces or salopettes that come high enough up your torso.
- The ski pass pocket: If your sleeve does not have one, store your pass in a left chest pocket. Avoid low hand pockets, which are often obstructed by a harness or backpack hip belt.
- Wrist sealing: Ski jackets often feature integrated Lycra cuffs. To recreate this barrier against the cold, opt for gloves with long arm warmers that cinch securely over your jacket cuffs.
The key takeaway: Using your hiking jacket for skiing is an economical and durable choice. Follow the three-layer system carefully and you can enjoy the powder in as much comfort as you would with dedicated ski kit.
