Waterproof Dry Bag
The Hydrus 20L Dry Backpack is built for paddlers who want their gear bone-dry and their shoulders happy. Airtight roll-top closure with welded seams keeps water out from light splashes through full submersion. External water-resistant zipper pocket holds phone, keys, and small items for quick access.
The carry system is what separates this from a basic dry bag. Padded shoulder straps with ventilated back panel and adjustable chest plus waist belts. It feels like a hiking pack, not a duffel. Hike to the launch, paddle the day, hike back, no shoulder fatigue.
Airtight design traps air inside, so the bag floats if it goes overboard. Sized to fit under the bungees on any Hydrus iSUP, secure and out of the way. 20-liter capacity expands for overpacking days: shoes, clothes, lunch, camera, layers. Right-sized for day trips, light enough for travel.
