5L Blue & White Stripe Waterproof Dry Bag Backpack – Compact, Stylish & Adventure-Ready

Lightweight, tough and built to brave the elements—the 5L Waterproof Dry Bag Backpack in bold blue and white stripe design is your go-to for quick outdoor escapes. Whether you're hiking, paddleboarding, festival hopping or dashing to the beach, this compact waterproof dry bag keeps your valuables dry, secure and easy to reach.

Made from durable 500D PVC tarpaulin, the bag is 100% waterproof and IPX6 rated, meaning it resists powerful water jets, dust, sand and grime. Just roll the top tightly at least three times and clip shut for a watertight seal. It even floats on water when properly closed, so your essentials stay safe—even in splash zones.

Ideal for children or as a compact adult grab bag, this 5L capacity backpack stashes phones, wallets, cameras and other must-haves. The two detachable, adjustable straps let you wear it as a backpack or belt-mounted bum bag, and with 4 D-rings, a carabiner and sturdy clasps, it’s primed for all-day exploring.
