The Caribee Adventure 70 Hybrid wheel travel backpack features fabrics that are made from recycled plastic bottles (RPET). Boasting a 70L main storage capacity with internal compression system and large mesh sleeve pocket, the Adventure 70 increases its appeal as a versatile travel bag with the inclusion of two front pockets that provide additional storage up top and a handy separate shoe pocket down low. The telescopic dual arm trolley system combines with quality all terrain wheels to ensure you glide through the airport and on to your travel destination. If the going gets rough, deploy the Adventure 70's concealable backpack harness system featuring padded shoulder straps and hip belt and convert your travel bag into a travel backpack. The harness cover stows in to the side of the harness (not the base) making this a comfortable backpack.
