The Varicom Gamma 0-Degree Sleeping Bag is a modular, military-grade sleep system designed to integrate seamlessly with other Varicom components — combinable with the Gamma bag for -15°F protection or with the full Delta, Gamma, and Bivy setup for -40°F performance, all ISO tested. Built for operators in hostile environments, it features an Enhanced Situational Awareness (ESA) hood that minimizes sound-blocking fabric around the ears, keeping you alert even at rest. Filled with Climashield Combat insulation for maximum warmth at minimal weight, it packs down into a military-spec compression stuff sack for superior portability in the field.
