WILD HEART Waterproof Bag Duffel Bag 20L 30L 40L with Welded Seams Shoulder Straps, Mesh Pocket for Kayaking, Camping, Boating,Bycycle,Motorcycle

I bought this bag to carry a pile of clothes and swimwear for our paddle-boarding adventures. It keeps the back of the car from being cluttered, and makes lugging our swimwear and clothes much easier. We keep our dry clothes and towels in the bag, where they stay dry, and afterwards our wet stuff and float jackets etc. go in the bag where the water won't make the car soggy! We can take the bag on the boards in a fully waterproof configuration, and it will carry more stuff in its water-resistant (but not waterproof) mode. Not cheap, but certainly good value!
