Hell Or High Water, This Pack Has It Figured Out

Your gear doesn't get a say in the weather. Neither should you have to worry about it. The Hydric 40L is a 100% waterproof roll-top backpack built for the moments when everything else gets soaked — river crossings, downpours, dropped packs, unexpected swims.

The problem with "water-resistant"

Most backpacks marketed to outdoor adventurers are water-resistant, not waterproof. That distinction matters the first time you're caught in real weather — resistant gear buys you a few minutes before your electronics, spare clothes, or food are soaked through. The Hydric 40L doesn't make that compromise.

How it actually works

Roll-top seal: Three folds and a buckle create a fully submersible seal — no zippers to fail, no seams to leak.
Welded (not taped) seams: Taped seams peel over time. Welded seams don't.
40-liter capacity: Room for a multi-day trip's worth of gear without the bulk of a full expedition pack.
Rugged UTX hardware: Built to handle abrasion from rock, boat decks, and truck beds — not just rain.

Built for

River trips and canyoneering. Hunting trips into the backwoods. Motorcycle and ATV runs. Fishing from a boat. Anywhere your gear is one bad moment away from ruined.
