Roll Top Waterproof Backpacks: The Sealed Carry
Roll closures, welded seams and the dry seal — how roll top waterproof backpacks actually keep water out.
Roll Top Waterproof Backpacks: The Airtight Seal
The short definition: a roll top waterproof backpack seals by rolling the open top three times and clipping it — creating an airtight, watertight closure without zippers. Combined with welded seams, it is the most reliable waterproof backpack construction.
The roll top is the waterproof standard — no zipper to leak, no flap to fail. Here's how it works.
Why Roll Top Wins
How the Seal Works
1. Fold the top edge over 3 times
2. Bring the side clips together
3. Clip both sides — the roll holds the seal
The more rolls, the stronger the seal — 3 rolls is the minimum for submersion.
