SealLine® builds the finest waterproof gear for paddlers, sea kayakers, surfers and backpackers. Our dry bags, portage packs, backpacks and dry sacks are designed and tested in Seattle by engineers who know and live these core sports. They match materials and design to create the most specialized, high-quality waterproof gear available. Each product is built in Seattle by technicians who draw on over 30 years of RF-welding experience. The differences in what we do matter, and they allow SealLine® gear to stand up to any weather or water on Earth.
