to ensure watertightness, as well as PVC-free 210D PU-coated nylon that is long-lasting and eco-friendly.weatherproof.

Radio-Frequency Welding
To make watertight seams on all SeaLline Dry Bags, SeaLline use radio-frequency welding. With this technology, there's no burning or melting invloved. Instead, the Dry Bag fabric is fused at the molecular level into a waterproof, welded, seam that is stronger than the fabric itself.

Dry Seal™ closure
Identified by a pair of black vinyl strips, the exclusive SeaLline Dry Seal™ closure seals more effectively than any other roll-down closure. Instructions are embossed directly on the strips making it easy to get a positive, watertight seal.

Storm Sacks will keep dry gear dry & are ideal for separating wet or dirty items from other kit eg; tents, waterproofs, boots etc.
