Liner Only. This is a Para Rescue liner kit for the No. L3104 Protec.
This liner was originally developed and patented headgear liner upgrade for U.S. Military Pararescue soldiers (PJ' s) after soldier complaints that the headgear was uncomfortable and often unstable. This liner upgrade solves both problems, providing exceptional comfort and stability. It also is waterproof and improves shock absorption.
The Para Rescue headgear liner upgrade kit is made from several materials, including visco-elastic foam. The Upgrade is equally effective for any Protec headgear application. It consists of three parts and can be installed in minutes without headgear modification. The upgrade eliminates pain by eliminating localized circulation loss ("hot spots") on the head and ears and is stable, even with external equipment such as night vision goggles. The liner upgrade' s exclusive breathable urethane coating releases heat and air from the scalp but resists water getting through to the scalp.
Comes in two sizes only.
