What Is The Best Way To Choose Thermals? – A Buying Guide

These are a few factors that you need to consider when buying thermals:

Material

This depends on where you are going, but the most common fabric is wool, for obvious reasons. Wool is the most viable, easily available, and easy-to-maintain fabric. There are other options too, like synthetic fabrics, but they are cheap-quality and tend to throw up a stink. Silk is another good choice but only in medium cold weather. It is expensive but feels great on the skin.

Fit

Thermals should fit snugly on your body without being skin-tight. Make sure you go one size smaller because they tend to expand with use and bulk up under your clothes, which can get extremely uncomfortable.

Comfort

Thermals are supposed to be as comfortable as possible. Ensure they are of good quality and brand. Avoid wool if you have sensitive skin as it can cause irritation. Always try out a few inexpensive pieces from a brand and see how they feel for a few days before investing in their more expensive thermals.

Breathability

Breathability is another vital factor you need to keep in mind. It refers to the garment’s ability to retain moist air between your skin and jacket without getting too saturated with moisture. A breathable garment helps you stay warmer for longer. Now that you know what you need to keep in mind when buying thermals, here are the best ones that can get your hands on right now.

Base Layers Vs. Thermals

Base Layers

A base layer is extremely tight and fits almost like second skin. Our bodies naturally sweat through our pores to maintain an average temperature, especially when we are fully covered with outerwear. The base layer, instead of your skin, absorbs sweat. Thus, wearing it in extremely cold conditions helps prevent evaporation of sweat into your clothes or body. In conclusion, a base layer is essentially a mechanism that prevents you from getting cold rather than keeping you warm. However, most brands give the best of both worlds – a base layer and thermals. Depending on the activity you will be involved in or your preference, you can go with either.

Thermals

Thermals are garments you wear under your clothing. They are made with soft and breathable fabrics that keep you warm. They are snug and don’t feel bulky under your clothes. They, basically, act as a great additional layer in icy weather conditions.
