Review on MIER Waterproof Dry Duffel Bag: Airtight TPU Dry Bag for Outdoor Adventures - Motorcycle, Kayaking, Rafting, Skiing, Travel, Hiking, Camping by David Norwood

This is a great holdall and it is waterproof. I closed it and put it on top and it didn't collapse. It comes with zip lube and has plenty of attachment points to attach it or tie things to it. By my standards it seems indestructible. And I'm tough on things. My regular use is what the manufacturer calls a torture test. My only issue with the bag is its odd shape. Due to the oval cylinder, it is very inconvenient to carry around. If I had to take another I would take the regular round bag they offer.
