Two sleeping bags (EXTREME and LITE), one modular cover. Mix and match for any condition from summer nights to deep winter.
The materials inside.
GRAPHINSULATE™ graphene and aerogel integrated fill macro
Graphene + aerogel integrated insulation fill.
Graphene distributes heat evenly. Aerogel traps it at the molecular level. Integrated at the fiber level, GRAPHINSULATE™ delivers exceptional CLO values and efficient weight-to-warmth performance, with reliable insulation even in conditions where traditional down typically struggles.
W.A.I.™ aerogel tubes reacting to cold exposure
Weather Adaptive Insulation. Completely passive.
Aerogel-filled tubes inflate in cold conditions to add insulation. They deflate in warmth to release heat. No batteries. No electronics. No input required. The same award-winning technology proven across the Graphene-X jacket line — now in a sleeping system for the first time.
Features
Engineered as a system. Every feature serves a function.
Modular design
Two bags + one cover. Connect them to extend your range. One system handles everything from summer to deep winter.
Air mattress integration
Lower mesh holds an inflatable mattress inside the bag. Sleep on it, not around it. Closer to a bed than a bag.
Arms free system
Full arm use without opening the bag. Your core stays sealed and warm while your hands stay mobile.
FIDLOCK magnetic collar
One-handed magnetic closure on the neck collar. Brushed interior fabric. Instant, secure, glove-compatible.
Graphene footbox lining
Extra graphene-integrated lining where you lose heat fastest. Targeted thermal engineering at the extremities.
Quiet fabric shell
Waterproof Nylon Ripstop 40D with reduced-noise construction. PFC-free DWR. Move without waking yourself up.
