"What Our Gearhead® Experts Are Saying: ""I’ve used this sling on long wading days, and being able to submerge it without stressing about the contents is huge. The hydrophobic strap also makes a difference—it never feels soggy or heavy, even after hours in the water.""We depend on the Guidewater 15L Sling Pack when our time on the water demands absolute trust in our gear. From pushing through brush along the bank to wading deep across shifting flats, we want a pack that swings forward quickly without compromising what’s inside. Patagonia built the Guidewater Sling Pack to stay dry, organized, and comfortably out of the way until the moment we need it. The submersible IPX-7-rated construction shields everything inside from full immersion, supported by a durable recycled nylon exterior and hydrophobic back panel that refuses to retain water. A dual-direction zipper creates smooth access from either side, making it easy to work through gear without breaking concentration. Internal organization adjusts to fit our system, and the net scabbard stays tucked out of the way yet instantly reachable. With compatibility for additional work stations and vests, this sling adapts to changing conditions and trip styles without missing a beat."
