Main features

Built for warmth, comfort and durability, this thermal shirt combines a snug fit with practical details that make it ideal as a first layer.

• Waffle knit construction: retains body heat while allowing moisture to move outward for breathability.
• Material: 65% cotton, 35% polyester for softness with added durability.
• Snug, ergonomic fit: close cut that preserves warmth without restricting movement.
• Low-profile seams: minimize chafing during active use.
• Thick collar and elastic cuffs: improve fit and help keep the shirt in place during activity.
• Designed as a first layer: works well under outer shells and mid-layers for layered systems.

How to use / When it’s useful

Quick answer: Wear this as your first layer in cold conditions to trap heat close to the body while allowing sweat to escape. It is suitable for hiking, tactical training, field work, and daily cold-weather wear.

In most cases, pair it under a mid-layer or shell for added insulation and weather protection. The snug cut and waffle texture make it useful for active duty, military surplus setups, police work, and outdoor sports where a balance of warmth and breathability is needed.

• Avoid bleach and do not tumble dry to prevent fabric damage.
• Reshape and dry flat or hang to dry to keep fit and structure.
