Your base layer is your best friend – it stays close to you providing you with the comfort you need and at the same time amplifying the fun you get while you ski. No one can enjoy skiing while shivering, and there can be times when you over-dress yourself and end up getting sweaty while you ski. Your baser layer provides you with moisture-wicking abilities and keeps you comfortable, cozy, and dry, saving you from feeling too chilly or worse – getting hypothermia.

Considerations for Choosing a Comfortable Base Layer

The art of layering your thermal shirts and jackets is crucial in cross country skiing. As you feel a little hot, you can take off a layer to feel comfortable. With your base layer on – which is your next to skin thermal layer – your skin does not get affected by your perspiration and the body stays dry.

While choosing your base layer, you need to understand the purpose and functionality of different layers. Your base layer is often referred to as your underwear layer (the layer of clothing you wear underneath your actual ski clothes) and its job is to keep the sweat off your skin. Your middle layer is the insulating layer that retains your body’s heat in order to protect it from the outside cold. The outer layer is the shell layer that provides a shield against the weather – wind, rain, and snow, etc.

Consider the following factors while choosing a comfortable base layer:

Fabric [wool or synthetic]

Make sure the fabric of your base layer is either synthetic or wool that wicks moisture away. Polyester and merino wool are known for their moisture-wicking powers and make excellent base layers. Avoid cotton as your base layer material as cotton has the tendency to absorb moisture (sweat) and holds onto this moisture, making you feel cold.

If a garment is designed to be a base layer, chances are it uses synthetic, merino, or merino wool that will keep your body warm and dry. If you are given options for the type of fabric to choose from, go for polyester, nylon, and natural fibers (merino wool and even silk). Although these fabrics may have different characteristics when it comes to drying, odor retention, and durability, they all make good materials for your base layer. For this reason, choosing the right fabric is crucial for your cross country skiing experience.

Synthetic

This includes nylon, rayon, polypropylene, or blends of these synthetic fabrics. Here are some of the characteristics of synthetics as base layers:

  • Synthetic fabrics are great at wicking sweat and therefore give you a super dry feeling.
  • These fabrics are long-lasting. Every fabric may go through wear and tear but synthetic fabrics are very durable.
  • Most synthetic fabrics are great in preventing the growth of odor-causing bacteria. This means that even if you go lazy and skip washing for a couple of days, you can still use your base layer without the smell.

Merino Wool

Merino wool is not like the traditional itchy wool, it is soft and has very fine fibers that make sure your base layer is as comfortable as possible. Merino wool is often blended with other fabrics, for instance, spandex to add the flexibility factor. It has some of these characteristics that make it a great option to be used as a base layer:

  • Merino wool is quite resistant to bacteria that cause odor, leaving you with an almost no stinky feeling.
  • Although it may not be as durable as many synthetic-based fabrics, you can put it on under other clothing layers to have a feeling of warmth and comfort. Since merino wool is made of soft fibers, constant rubbing can weaken down the fabric. There are many base layer pieces of clothing that mix wool with synthetics to come up with a perfect base layer.
  • Merino wool absorbs a little bit of moisture which is not too much to make you shiver but you may not feel as dry as when you put on a synthetic base layer. This is the reason why it takes a longer time to dry off if it gets wet.

Long or Short Sleeve Cut

Whether you should go for a long-sleeved base layer or a short-sleeved one depends upon the winter temperature, your metabolism, as well as your comfort level. Many skiers want their arms less covered for a better movement, while others prefer a full-sleeved shirt. Similarly, many skiers get sweaty too quickly while skiing and want a sleeve that will be according to their preference.

Long sleeves will give you better coverage against cold winters. If you feel the temperature is not too cold, you can put on a short-sleeved or sleeveless base inner layer and wear a long-sleeved middle layer and jacket.

Your long sleeves can have many options: lightweight, midweight, and heavyweight. You can put on lightweight for moderate to cool temperatures, mid-weight for cold temperatures, and heavyweight long sleeves for when the temperature is touching the minus mark and goes below the freezing temperature.

It is important to remember that the main job of your base layer is to keep you dry and not add too much warmth. If you feel your arms get too sweaty when you ski, it is better to go for a long-sleeved base layer so the entire upper body stays dry and comfortable. If your metabolism and external temperature do not get you much sweaty, you can go for a short cut sleeved base layer.

Flexibility and Comfort

A golden rule of thumb is to put on your ski clothing in a way that when you start skiing, you feel a bit cold (not too cold as this cold level still has to be bearable) because as soon as you start skiing, your body will start to heat up and you will feel fine. Over-clothing yourself with a heavy base, inner and outer layers will only make yourself hotter and sweatier than you would want to feel.

Many base layers use a mix of spandex to give you the fit and flexibility you are looking for. Your base layer needs to have a wicking fabric that is directly touching your skin to give you a comfortable fit. If you want your base layer to dry you off, it must be as comfortably close to the skin as possible.

You will find many athletes who prefer a relatively loose base layer than what their actual fit is. They do so to facilitate the air circulation and cooling while they sweat out. This logic may work for warmer weather as the sweat evaporates due to the passing air.
