The Arva Explore 30 Switch Cover is the shell half of a modular avalanche airbag backpack built for ski touring and splitboarding. On its own it carries a 30-liter capacity, diagonal and A-frame ski carry, snowboard-compatible carry, two ice axe loops, and a built-in helmet holder. The shell uses recycled polyamide, and the liners use recycled polyester. Pairing it with Arva's Switch Frame and Reactor 2. 0 airbag system completes the pack. What Our Gearhead(R) Experts Are Saying:"I stop for a skin change without ever setting the pack down. The bottom compartment sits below the main compartment, so skins, crampons, or a water bottle come out from underneath without unpacking anything on top of them."
