Filson Dry Backpack Backpack

The "Dry Backpack" from Filson is made from durable 840 denier nylon tarpaulin fabric coated with Thermoplastic polyurethane (TPU), ensuring that water does not penetrate. The coated nylon fabric is lightweight, flexible, and highly abrasion-resistant. The TPU coating is resistant to ultraviolet rays and chemicals, guaranteeing long durability and lifespan without breaking even under hard use. The seams are high-frequency (RF) welded, a process that permanently fuses layers of fabric without the use of cement, ensuring lasting flexibility and integrity. All webbing and pads are securely stitched to an additional waterproof fabric layer and then RF welded to the main body of the bag. Designed for effective waterproof protection, it allows you to carry your gear comfortably in even the wettest conditions. 【Material】 Main body: 100% nylon Insulation part: 100% PE foam - A4 compatible (22×31cm): Yes - Long wallet (10×20cm): Yes - Bottled water sideways (500ml): Yes - Bottled water upright (500ml): Yes
