Types of Waterproof Dry Bags: Sack, Backpack Dry Bag, Duffel Dry Bag, Phone Pouch

A lot of people think all waterproof dry bags are basically the same: a waterproof body, a roll-top opening, and maybe a shoulder strap. But once you really start using them, or once you start developing them for your own brand, the differences become very clear. A 5L sack dry bag for kayaking essentials is not built the same way as a 30L backpack dry bag for paddleboarding. A large duffel dry bag for overlanding or marine trips has very different load-bearing needs from a waterproof phone pouch sold at tourist shops or beach resorts.
