Base Layers & Underwear

Base layers are the most important part of your clothing system – the layer worn directly against your skin that has the biggest impact on comfort, temperature regulation, and overall performance. A well-chosen base layer moves moisture away from the skin, helps regulate body heat, and reduces chafing during both active and stationary use.

In MilGear’s selection you’ll find technical base layer sets, shirts, and underwear designed for field use, shooting range activities, work, and outdoor use. Options include synthetic materials for efficient moisture wicking as well as warmer alternatives for colder conditions.

A good base layer fits close to the body without restricting movement and works as part of a layering system. It keeps your skin drier under load, improves comfort when wearing gear, and helps maintain a more stable body temperature in changing conditions.

Whether you're hiking, training, working, or just staying active outdoors, a proper base layer makes a noticeable difference.
