A very enhanced dry bag duffel. The usual tough and abrasion resistant ultrasonically welded PVC plus a full length TIZIP waterproof zipper protects your clothes, electronics, camping gear, paperwork, etc. Padded handles are quickly converted into comfortable and adjustable backpack shoulder straps for off-bike trekking too. Opens like a big bottomless cave to swallow whatever you store inside and internal straps compress the volume to maximize space and keep contents held securely in place. Two internal pockets and one outer mesh pocket (which is not waterproof) make quick access to often used items a breeze. Zipper loop can be locked with padlock (not included) to keep contents secure. Three versatile sizes: Small (60L) 9.3"x18.6"x11.3' (3662 cu. in.), 41.7 oz. Medium (85L) 12.2”x25.6”x17.3” (5187 cu. in.) 48 oz. Large (110L) 13.4"x27.6"x18.1" (6713 cu. in.) Black, Yellow or Blue.
