The Competitor’s Choice: Protects your gear in the most extreme conditions.

Isosceles Storage System™ backpack (patented):
Two side pockets hold boots surrounding a large central compartment that accommodates a helmet and gear. Weight and bulk from boots is diverted to the sides and away from your back creating a natural suspension that is ergonomic and comfortable. Moisture from melting snow from boots in side pockets is drained and vented through grommet air/water holes. The large central compartment is protected by water resistant coated fabric to keep objects in the central compartment dry.
