Blizzard Survival use the unique material Reflexcell to produce superlight and reuseable emergency thermal products. Reflexcell has a cellular, waffle-like construction to trap warm air, elastication which draws the material to the body, reducing cold spaces and heat loss by convection, and finally, silvered surfaces to block heat loss by radiation. It is also completely waterproof and windproof.
This unique combination gives Reflexcell vastly superior warmth to any comparable emergency product. However its greatest strength is that it can be compressed into the tiniest of packages and stored indefinitely without damaging its performance.
