5L Watermelon Waterproof Dry Bag Backpack – Small But Mighty
Say hello to splash-proof style! The 5L Watermelon Waterproof Dry Bag Backpack is your compact companion for quick adventures, muddy trails, and wild swims. This mini dry bag packs a punch with 100% waterproof protection, crafted from tough 500D PVC tarpaulin and sealed with a roll-top closure. Lightweight, rugged, and ready to roll—literally.
Whether you’re hiking, biking, paddle boarding or simply chasing sunshine, this bag keeps your essentials safe from water, dirt, sand, and snow. It's IPX6 rated, meaning it’s fully dustproof and deflects powerful water jets from any direction (just roll it tight at least three times and clip it to seal).
Perfectly sized for kids, or as a grab-and-go dry bag for adults. Clip it to your belt to transform it into a bum bag, or sling on the detachable backpack straps for hands-free adventures.
💡 Key Features:
- 5L Capacity – Ideal for phones, keys, snacks & sunscreen
- Floats in water when sealed properly
- Waterproof welded seams for extra protection
- 4 D-rings & carabiner attachments
- Rubber grab handle & strong clasps
- Easy to clean – warm soapy water or lemon juice works a treat
- Compact dimensions: H35 x W15cm (cylindrical), H45 x W15cm (flat)
- Lightweight – just 320g
Store in a cool, dry place out of direct sunlight, and keep it adventure-ready.
