The All-New Highwater Hitchhiker attaches to the TravelinkTM Sling (or just about anything) with two velcro attachment straps. It's also MAGNEPODTM compatible, allowing you to secure it to BOTE products with MAGNEPOD attachment points. Plus, the included carry strap allows for multi-wear, hands-free carrying. The patented TRU Zip zipper is fully waterproof, dustproof, airtight, and submersible (IP67).
