SealLine Discovery Deck Bag 30L

  • Product Number: 3091

The ultra-durable Discovery Deck Dry Bag is our top-of-the-line dry bag loaded with features while delivering resolute waterproof protection from day trips to expeditions. Whether lashed to a paddle board, stowed in (or on) a kayak, slung over a shoulder, strapped atop a car, or attached to a motorcycle, you can count on the Discovery Deck Dry Bag's heavy-duty, waterproof performance.


  • PurgeAir-equipped: Our unique and waterproof PurgeAir valve vents trapped air, helping the dry bag compress further after being sealed, and is both more durable and more reliably waterproof than waterproof/breathable fabric membranes.
  • Adaptable: Adjustable carry strap and multiple lash points make it easy to carry or anchor the bag.
  • Built for the journey: Made of rugged, flexible, and fully waterproof materials designed to withstand frequent and demanding use.
  • Light-colored interior: Significantly eases identification of contents within.*
  • Oval bottom: Stable shape won't easily roll around; it's also easy to store, stack, and pack.
  • Durably constructed: Fully welded seams result in stronger and more durably waterproof construction compared to sewn-and-taped seams.
  • Tight, simple sealing: DrySeal roll-top closure makes it easier and more intuitive to achieve an optimal seal.
  • PVC-Free: Materials have a reduced environmental impact over vinyl-coated materials.
