D-FY.IT: World’s Most Waterproof Everyday Backpack

Yes. The outer material is abrasion-resistant 840D ballistic nylon with external polycarbonate coating. It’s built to last, and doesn’t wrinkle. The inner waterproof lining is separate and protected, meaning it avoids wear from sun exposure or friction, significantly extending its life.

Yes. D-FY.IT is made to fit well on any body type, with ample strap length.

Generally, yes. The bag is fully submersible, has a suspended laptop compartment, and includes structured padding (including on the bottom). That means your electronics stay well protected from both water and minor impacts.

Yes. We put a lot of effort into making the bag look nice both empty and loaded without adding a ton of padding. The outer shell holds its shape even without being packed full, so it never looks floppy or collapsed. The structured build makes it easy to load and keeps the silhouette clean.

Both fabrics can simply be wiped with your hand in case of light dirt. In case of heavy dirt, a damp cloth should do the trick. The inner waterproof lining can be partly removed for easy rinsing. It dries fast and doesn’t absorb odors or water.

Yes. The materials used retain flexibility and sealing ability even in low temperatures. It’s been tested in snow and wet-cold conditions with no performance drop.

D-FY.IT is semi-structured: it holds its shape when worn or set down but can compress slightly when needed. That balance makes it ideal for squeezing into overhead bins, lockers, or under seats.

If you rolled it tight, the air trapped inside the dry bag will pop it out of water, and it will float. We recommend you take it out of the water ASAP and do not keep it submerged for more than a brief period of time.
