”Welding” used to mean using extremely high heat to unite two pieces of metal. Now, it just means using heat to securely join two similar pieces of material. The Stormfront Pack, Westwater Duffel, and the Dry Creek Boat Bag all use welded construction, which means there are no sewn seams for a union that is less bulky. TPU or thermoplastic polyurethane keeps the nylon or polyester material waterproof, and when applied as a liquid solvent, it cures into a flexible, abrasion-resistant membrane.
Four Bags, Four Uses
Patagonia’s Stormfront Pack (1) is a waterproof backpack for fly fishers on foot. For boats and rafts, use the Simms Dry Creek Boat Bag for easy wide-mouth access. Columbia’s Axel Hauler (22″) is a water-resistant carry-on roller bag, but for truly large capacity you’ll need FishPond’s Large Zippered Duffel that converts to a backpack.
