The Osprey Kode ABS 2210 Pack is an ABS compatible pack which allows you to have all the features you love from the Kode pack plus top of the line avalanche protection. The Kode ABS has a detachable backpanel that unzips from the pack, which allows you to zip the pack to a ABSR Vario Base Unit. The Kode ABS pack has panel access with a zippered 10L expansion of the dry compartment to help accommodate more gear for extended trips into the backcountry. Snowsport specific features such as multiple ski and snowboard carry options, stowable helmet carry, and reinforced wear points make the Osprey Kode ABS 2210 Pack an all around winner. Note: ABSR Vario Base Unit is sold separately.
