The Patagonia 15L Guidewater Sling is built with a sturdy body and webbing made from 100% recycled nylon, while the back panel, shoulder strap, and lining are made from 100% recycled polyester. This fully waterproof sling is IPX-7 rated for submersion, providing reliable protection for contents with a 15-liter capacity. The hydrophobic back panel and shoulder strap resist water absorption, enhancing performance in wet environments. An integrated net scabbard in the back panel offers convenient, out-of-the-way storage. A dual-direction zipper enables easy access from either hand, and the internal organization can be adjusted for personal preference, making it functional for wear over either shoulder. The internal organizer pocket keeps smaller items separate from the main compartment and can be moved to external lash points for fast access when needed.
