The HalfJak™ is a new minimalist concept in combat-specific weather protection. It helps you stay warm and dry while avoiding overheating during movement. No needing to stop and remove kit to layer up or down. No interference with your gear and no delays while you’re on the move. Instantly transition back and forth between highly-aerobic and stationary activities without getting sweaty or cold.

Traditionally, operating in cold/wet weather meant that you could only: A) carry a bulky coat that you can’t operate in, B) freeze now so you won’t sweat later on, or C) layer up now and hate life later when you’re moving and sweating. Now, you can just throw the HalfJak™ on over your kit to stay warm and dry, and then shove it back in its stuff sack when you’re moving. Simple.

We’ve been making custom versions of this design for years – based on popular demand we are now making it available to the public.

The HALFJAK™ INSULATED version is our new take on combat-specific cold/wet gear. Made with ClimaShield™ loft material, it is extremely light, packable, and warm. The exterior fabric is treated with a NanoSTX™ finish that keeps the water out.
