Features:
* 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 (Note: The light-colored interiors are achieved by using materials with non-dyed white threads that have a clear interior coating and a solid-colored exterior coating. The plaid bags use materials with dyed threads and clear coatings inside and out—they do not have as light of an interior as a solid-colored bag, though still maintain some translucence)
* 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: Updated 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
