Skiing or snowboarding requires warm jackets that are at the same time flexible, comfortable, waterproof, and resistant to bad weather. Millet, Poivre Blanc, Degre7, and Volcom, not to forget Burton and Norrona, are among the most popular brands. You need a ski jacket that will protect you from the cold (thermal insulation), from external moisture (rain, snow), and that will also naturally allow sweat to evaporate.
- The multilayer principle :
The main idea of multilayering is to juggle with 3 layers of clothing to face all kinds of climates :
- layer 1: technical base layer to wick away sweat (Odlo)
- layer 2: thicker layer to produce warmth (Millet, Degre7, Norrona)
- layer 3: protection against external climatic aggressions, rain, snow, and wind (Millet, Poivre Blanc, Degre7 ...).
You first need to define the use of your ski jacket. Do you need a very technical jacket to ski whatever the weather? A jacket for snowboarding, freestyle, or freeride? Or a jacket for very occasional use on the slopes?
If you ski one week per year, mainly on sunny days, a water-repellent jacket (see explanations below) will be enough (Degre7, Millet) but less durable over time than a membrane model (Eider or Volcom).
If you snowboard, snow jackets are more specific. They have a wider cut for greater freedom of movement. Time spent sitting in the snow does not alter the insulating capacity of your snow jacket.
For freestyle skiing, jackets are very similar to snowboarding jackets.
For freeride use, the jacket must be technical, with a high-performance and breathable membrane (Gore-Tex membrane for example) to stay warm and dry whatever the conditions.
For thermal gain without loss of ergonomics, you can combine a base layer with a technical Odlo t-shirt (which wicks sweat).
A fabric is by definition not waterproof, because it is woven. Indeed, the weave, however fine, leaves many gaps between the threads (just look at a fabric against a lamp light to notice it). To improve the fabric’s ability to protect against bad weather, two techniques are used :
It consists of a superficial application of a water-repellent substance that lets water droplets slide off. But this technique does not make the garment truly waterproof. Indeed, when the fabric is subjected to too much water pressure, the water ends up penetrating it. Moreover, these treatments resist washing machine poorly (after 3 or 4 washes, their efficiency is generally strongly reduced). But you can re-treat them with waterproofing sprays when necessary, or with specific products that provide water-repellent treatment.
Most low and mid-range ski garments are water-repellent. That said, a water-repellent fabric is sufficient for less intense use of a piste ski jacket.
Waterproofness is ensured by an independent membrane, called coating, which is a thin layer of material applied. For sports use such as skiing or snowboarding, it is preferable to choose a breathable coating or membrane like GORE-TEX which allows sweat to evaporate as water vapor. These fabrics are much more durable over time than water-repellent treatments.
This process allows a garment to be very waterproof and breathable, but it can still remain permeable to water at the seams. On technical garments (Millet or Volcom for example), the seams are sealed with a heat-sealed tape. These are ""sealed seams"" or ""heat-sealed seams"".
