Pack Smart. Carry Hard.
A true backpack should be able to carry it all. Your photography gear, a sweater, a bottle of water, and those snacks you need to keep going on your hike.
With D-FY.IT, you get dedicated pockets and compartments right inside the dry bag for all your gear, fasteners to hold camera lenses, meal flasks, and sandwiches in place, and 20L of capacity that can expand to 27L.
And for all those things you like to store upright, two pairs of removable internal side straps let you secure taller items like water bottles, tripods, or folded umbrellas—without them tipping over or shifting around.
Secured and Protected
When you’ve got things to do, the last thing you need is doubt. With D-FY.IT, you’re confident that your equipment is well-protected while you do your thing.
Your laptop is padded and raised for protection against impacts, and your valuables stay safe against theft inside the hidden security pocket.
Comfort? Check.
Roam the world, bring your gear, and carry it around comfortably.
Thanks to EVA foam padding — which is porous for superior airflow and ventilation — D-FY.IT doesn’t shift around, doesn’t chafe, and doesn’t soak your back in sweat. Even with a 15” laptop, two bottles, and a camera cube inside.
Thoughtful details like shoulder strap loops (perfect for sunglasses or a future chest strap) and anti-dangle fasteners keep everything streamlined and secure. And with padding in all the right places, all that gear feels like nothing at all.
Cushioned for Comfort
Close It Your Way
Your bag, your choice. Roll the top tight using the closure method you prefer, secure it with the tension-tested G-Hook, and you’re off.

Spot Your Items, Instantly.
Ever lose track of your keys, charger, or pen at the bottom of a dark bag? Not anymore.
D-FY.IT is lined with a high-contrast interior that makes everything inside stand out, even in low light or on the move.
External webbing fasteners on the shoulder straps let you attach carabiners or clip-on accessories, while dedicated loops keep your sunglasses secure and ready.
And unlike typical dry bags, it’s fully organized inside: raised & padded laptop sleeve, internal pockets, and vertical holders that keep your gear exactly where you left it.
