When it comes to any outdoor activity, having the right gear plays a crucial role as there is always a thin line between a fantastic and terrible experience in the wilderness, and skiing or snowboarding is no exception. Understandably, ski jackets or ski pants are the most popular items to look for before hitting the slopes, however, what’s going to help you stay warm, though, is wearing the best wool base layer under all those cool-looking ski gear.

The market for ski base layers can be pretty intimidating at first glance, as there are a lot of styles and materials to choose from. That’s why we not only brought you the ski base layer reviews of some of our favorite brands but also prepared a comprehensive buying guide so that you can make a more informed decision.

How To Choose A Base Layer For Skiing – Buying Guide



There are three main styles of ski base layers: jackets, shirts, and blouses. A jacket is an underlayer that zips up while a shirt is pulled over your head to wear and doesn’t always feature a zipper. Blouse-style base layers are similar to shirt-style base layers but they have a looser fit.


Let’s start with the most popular material first – merino wool. Wool is a natural fiber rather than synthetic and it comes with a lot of attractive features. For one, it offers great odor control. It can even go through several uses before it accumulates an unpleasant smell. It also wicks away moisture well. The biggest drawback though is that they’re among the most expensive options. While the material is durable, synthetic fabrics do surpass it in durability.

The second most common choice is synthetic fabric polyester. These fibers are made to be moisture-wicking, so they’re particularly popular in the sportswear market. The manufacturing of the polyester fabric itself has a large impact on how well it wicks moisture away but many companies also use a coating to increase the effect.

Polyester skiing base layers are often mixed with nylon or spandex. These help to increase how well the underlayer stretches to give you a tight, form-fitting underlayer. While less expensive than wool, the synthetic material collects body odor quickly.

Today, silk layers are usually treated to offer better odor control and increased moisture-wicking properties. The biggest disadvantage of silk is that it’s very fragile. It has to be hand washed and you can’t put it in the dryer either.


Different manufacturers have different descriptions but in general, you can break these sizes down to lightweight, midweight, and heavyweight base layers.

A lightweight underlayer is best for skiing in the spring as it won’t feel too heavy. Advanced or professional skiers also prefer this type because even when it’s cold out, high levels of exertions raise their body heat.

Midweight base layers are the happy medium between heavy and light base layers. The best choice for most average skiers, these work well to keep you warm during moments of inactivity such as when you’re riding a chairlift. On the other hand, they don’t leave you uncomfortable or overheated when you’re skiing.

Heavyweight layers are very thick, are the warmest underlayers, and they typically wick away moisture very well. These are only meant for low temperatures with low levels of activity. Otherwise, you’re likely to overheat quickly.


As we’ve mentioned at this point, weight and warmth go hand in hand. But, to choose the right layer, you have to know the level of warmth you need. There are a few factors to consider.

First, you’ll want to consider the weather. Don’t make the mistake of thinking that the presence of snow means you need thick layers at all times.

The other factor to consider is your level of activity. If you’re taking simple, light-hearted paths, you don’t have to worry about getting overheated. Unless your level of activity is incredibly low, you want to lean towards midweight layers.

If you plan on taking more intense, challenging slopes, you want to look for a lightweight option. These will keep you warm enough but they won’t make you uncomfortably warm or cause you to overheat as you ski.


Top-rated underlayers for skiing are made with breathability in mind. Synthetic materials and wool, in particular, are great choices when it comes to airflow. However, a base-layer can only do so much. Therefore, it’s a good idea to be on the lookout for top layers that complement the need for breathability. Inner leg and armpit zips are a couple of key features. This also helps the moisture your base-layer is wicking off of you to evaporate.

Drying Speed

Some fabrics dry faster than others. Synthetic materials such as polyester and nylon dry the fastest. Wool, on the other hand, takes a little longer to dry but it isn’t unmanageable. Drying speed is the main reason you want to avoid the rare cotton snowboarding underlayers as cotton takes a notoriously long time to dry completely.

Layering Ability

Make sure that your underlayer is not too thick so that you won’t have trouble using a layer on top of it. Your base-layer for snowboarding should also fit tight with stretch so that it won’t restrict your movement when you’re taking on a high-energy sport.


Among the materials we’ve discussed here, synthetic fibers win out on durability. Specifically, nylon underlayers are the strongest choice with polyester trailing not too far behind. Merino wool does have less durability than synthetics but it’s a much stronger choice than silk.


You don’t want something too loose because a baggy underlayer doesn’t offer the same warmth. It also will fit awkwardly underneath a top layer. However, as we’ve mentioned, you don’t want something suffocatingly tight either.

Again, synthetic fabrics are the best choice for this stretchy and breathable but tight fit. Keep an eye out for flat seams too. This minimizes problems like chafing. It can also be helpful to look for garments with other convenient features like high necks for warmth or thumb loops to keep your sleeves in place. Long sleeves, long cuffs, and a long back keep you warm.



Q: What thickness base layer do I need?


Lightweight layers are made for moderate temperatures which make them a great choice for spring. Midweight layers are made for cooler temperatures, so they work well through most of the winter. Heavyweight layers are meant to be used in temperatures below freezing. If you wear it in warmer weather, you risk overheating.

Aside from the weather, you need to think about your skill level and plans. Ultra-lightweight or featherweight is incredibly light and usually only work well for serious skiers who are highly exerting themselves on intense slopes. If you will be taking more casual paths, opt for a midweight under layer.

Q: Should my base layer be skin tight?


The truth is that you want something tight enough to sit right against your skin but not so tight that it’s restrictive or uncomfortable. This is why the best base layers snowboarding use materials that have a little stretch and lots of breathability.

Q: How to clean and store my base layer when not in use?


You should clean your underlayer at least one time during the season with standard soap. After that, make sure it is completely dry and then use a waterproof sealant to maintain the moisture-wicking properties. When the season is over, it’s not a bad idea to pick up some soap treated with a water repellent specifically for ski gear.

Many manufacturers also give you recommended care instructions, too.

Q: What other activities can I use my base layer for?


The best cold-weather underlayer can be used for any wintertime activity such as chopping wood, shoveling snow, or wintertime jogging.
