Frequently Asked Questions

Base layers are essential garments worn next to the skin to help regulate body temperature, wick away moisture, and provide insulation during outdoor activities.

Mens base layers are usually made of synthetic materials such as polyester, nylon, or merino wool. Merino wool is a popular option due to its natural odor resistance and breathability.

Mens base layers come in different styles, including long-sleeved tops and short-sleeved tops. Some base layers also come with additional features such as built-in sun protection and flatlock seams for comfort.

Mens base layers are ideal for any outdoor activity where you need to regulate your body temperature and stay comfortable. They are perfect for skiing, snowboarding, hiking, camping, and other outdoor activities.

When choosing a men's base layer, consider the activity you'll be doing, the weather conditions, and your personal preference for material and style. Look for base layers that fit snugly but not too tight, and consider features like moisture-wicking and odor resistance. It's also a good idea to choose base layers with UPF protection if you'll be spending time in the sun.
