Waterproof Roll-Top Backpack 10L

The Swiss Gear SP435R is a 10 litre waterproof backpack built with seamless welded construction. It uses 0.6 mm thick PVC at the base and 0.3 mm on the sides to protect contents during water sports. A roll-top closure with zipper secures the opening, and a transparent window lets you view a phone screen without removing the device. An included touchscreen-compatible phone case adds a second layer of protection.

Suited for Water Sports Not Daily Commutes

Kayakers, paddle-boarders, rafters and beach-goers who need reliable splash and brief-submersion defence will find the roll-top seal and welded seams effective. The lightweight nylon build and adjustable straps keep the load comfortable for hours on the water. Commuters wanting a laptop sleeve, internal organisation pockets or a rigid back panel should look elsewhere, as the bag offers a single main compartment and no structured padding.

10 Litre Capacity Adjustable by Rolling

The bag provides 10 litres of storage when fully extended, and the roll-top design lets you reduce volume by folding the top edge down before clipping it shut. This single figure determines whether the pack can hold your gear for a day on the water or a weekend trip.

Questions about this item

How much does the 10L capacity shrink when I roll the top down for a full day on the water?

Rolling the top edge reduces usable volume; the bag adjusts from the full 10L down to whatever size you need by folding the roll more or fewer times.

Will the 0.3 mm side walls and 0.6 mm base hold up to all-day sun and abrasion without overheating my gear?

The 0.3 mm side material and 0.6 mm base are wear-resistant PVC that wipes clean and handles extended exposure in hot, wet conditions.

Does the included phone case fit a standard smartphone so I can leave my device inside the bag all day?

Yes, the free waterproof phone case is touch-screen compatible and designed to hold a typical phone while staying sealed inside the dry bag.
