Spire Vest 3.0 P.A.S.

Highmark Spire 3.0 P.A.S. Avalanche Airbag Vest

When you’re pushing into steep country on sleds, you don’t want heavy gear slowing you down — but you do want life-saving protection you can trust. The Spire 3.0 P.A.S. is our pinnacle for riders who demand maximum coverage with minimal weight.

Note that all Avalanche Airbags are sold without a cylinder. To complete the Avalanche Airbag, you'll need to also add on to your cart.

Why choose the Spire for snowmobiling backcountry?

• Protection-Airbag System (P.A.S.) for neck, chest & head trauma mitigation — this isn’t just about floatation, but protection from impact.

• Driven by Snowpulse 3.0 technology: ultracompact, integrated inflation + air amplifier in one housing to reduce bulk.

• Intuitive deployment handle, height adjustable and bright orange for quick visual cue under stress.

• Ultra lightweight build: the system weighs less than 1kg for the inflation mechanism alone, and the pack (airbag + cylinder) keeps the total sled-ready weight minimal.

Real-world durability & reliability

We engineered the Spire for mountain conditions — freezing temps, whipping winds, abrasion from snow and gear. Every seam, tether, latch, and cartridge interface is stress-tested under conditions you ride in. This is an avalanche airbag vest built for snowmobilers by snowmobilers.

Bottom line
