Designed to keep your gear protected when things get wet, the Advanced Elements Blast 22 backpack is ready to tackle whatever Mother Nature can muster. Made from TPU-coated 210d nylon, it has a welded seam construction that locks out dust and water. The roll-top opening allows for easy loading and unloading, and prevents water from seeping through the top when closed. A padded mesh back panel works to keep your back comfy and dry all day long, while an adjustable sternum strap prevents the pack from shifting while you’re on the move. Additional features include water-resistant zippered pockets and external gear loops.
