Base Layer FAQs

What are base layers used for?

Base layers help manage warmth, sweat, and comfort under outer clothing. They are useful during cold weather, long outdoor events, or field days with changing temperatures.

Should base layers fit tight or loose?

Most base layers work best with a close fit so they can manage moisture and layer cleanly under other clothing. Avoid anything so tight that it restricts movement.

Are thermal layers useful for paintball and airsoft?

Yes. Thermal tops and bottoms can help during cold games or overnight events, especially when players are alternating between high activity and downtime.
