The Guidewater Roll Top Pack holds an IPX-6 waterproof rating, built on 800-denier recycled nylon fabric coated with TPU front and back to keep gear dry through extended exposure up to the roll-top closure. That same roll-top design lets the pack expand or compress to match a day's gear load, from a stripped-down river run to a fully loaded saltwater trip. A padded, removable waistbelt and mesh-backed shoulder straps distribute the weight evenly across long days on the water. What Our Gearhead(R) Experts Are Saying:"I've had this pack take a direct wave over the bow on a skiff and pulled my gear out bone dry. That's the moment an IPX-6 rating stops being a spec on a page and starts being the reason I trust what's inside."
