The SPIRE is unlike any other Vest on the market.  It’s made of a super lightwieght material that reduces weight, increases mobililty and makes for a much cooler experience – temperature wise and otherwise!  The SPIRE includes a Protection Airbag System (the kind that deploys around your neck and chest), meaning that this lightweight vest can provide Trauma Protection in the event of an avalanche unlike any other avalanche airbag on the market.
