For those seeking an added level of safety without the weight and volume of an airbag pack. The SB 30L, featuring the Safeback avalanche survival system, is one of the lightest avalanche safety packs on the market while also being fully featured. The SBX system can be easily removed and only takes up .75L in the pack vs. the 4-6L of a typical airbag pack, giving the SB 30L the ultimate versatility.
