Depending on how much you ski, you may need more than one ski jacket. There are a few factors you should consider, such as Down insulation or Synthetic insulation, waterproofing, and breathability. The best jacket will provide the right combination of all these features, so you can ski with confidence.
Down Insulation
A good rule of thumb is to have at least one ski jacket. If you want to be as warm as possible while skiing, you should add thin jumpers under your ski jacket. If you're more adventurous, consider buying ski-specific wool jumpers. Wool jumpers will keep you warmer than cotton jumpers.
The warmest jackets have both insulating and moisture-management properties. They trap warm air in and provide a solid layer of warmth against extreme cold. However, you'll need to wear a base layer underneath to prevent the cold from seeping in. These jackets are also best for skiers and snowboarders who ride in extreme temperatures.
The number of ski jackets you have depends on your preferences and your budget. If you go skiing often, you may need a few different types of ski jackets. You may want a lighter jacket in warmer weather, while a heavier jacket is more comfortable for colder days.
Synthetic Insulation
Synthetic insulation is a popular alternative to down in ski jackets. The synthetic fibres used in these jackets allow the body to breathe and help keep the body warm in high-output activities. Some jackets are made with Polartec's Nano-Air or PrimaLoft's Alpha fibre.
Synthetic insulation is made of man-made polyester strands that imitate down filaments and form air pockets to trap warm air. Synthetic insulation is also water-resistant, which means it retains its insulating properties when it gets wet. These jackets are also better for wet conditions. Synthetic insulation is typically measured in grams per square metre. The higher the insulation content, the warmer the jacket will be. The average jacket has 50 to 100 gs of synthetic insulation, which is sufficient for spring and autumn temperatures.
Synthetic insulation in ski jackets can provide the same protection as down but have several advantages over down. It is a more comfortable choice when you're skiing in wet weather, where down clumps up and is ineffective in trapping heat. Synthetic insulation can also be safer for activities like bushwhacking, as a down jacket can rip and lose insulation.
Waterproofing
Waterproofing is a key feature to look for in ski jackets, as it helps you stay dry and warm during a day on the slopes. Typically, 10,000mm of water resistance is sufficient for most people, even when they're skiing in a powdery bluebird sky. However, if you're going to be out in the backcountry, you may want to upgrade to a 20,000mm-rated jacket. These jackets will offer maximum waterproofing and breathability, and will cost more than a 10,000mm jacket.
The best water repellent formulas for ski jackets are those that offer durable protection and don't require frequent re-proofing throughout the season. These formulas are effective on most materials, including nylon, polyester, and fleece. They are also easy to apply at home and offer factory-level performance.
Breathability
Breathability of ski jackets is an important factor to consider when choosing one. A jacket with high breathability will allow the wearer to breathe, and it will prevent you from feeling clammy or damp during long days on the slopes. Breathability is measured in g/m2 per 24 hours. The higher the number, the more breathable the jacket will be.
Breathability is important for any ski jacket, regardless of brand. A high DWR (durable water repellent) coating will prevent water vapour from penetrating the weave, while still allowing the wearer to ventilate. When the DWR coating is worn away, the jacket will become less breathable. The face fabric may also begin to absorb water, a process known as "wet out." This decreases the fabric's ability to wick away moisture, which is one of the primary purposes of a ski jacket. A softshell ski jacket will not be affected by this problem, but it will be less effective in wicking moisture.
Weight
Whether you're a newbie or an expert skier, the right ski jacket is a personal choice. You should consider the different materials and features of different jackets and decide which one is most suitable for your needs. Typically, ski jackets come in two types: soft shell and hard shell. Soft shells are light and breathable, while hard shells are waterproof and windproof.
Soft shell pants and socks should be included in your collection. While you're at it, consider investing in a pair of stretch pants. They have a similar look and function to standard ski pants. You'll also need a good pair of ski socks for every day of the trip.
