The Yeti Panga Submersible Backpack 28 — made from the same waterproof material (with waterproof zippers) as the Submersible Duffel — can endure dunking and downpours. Handy straps and lash points offer versatility and comfort. The chest strap and waist belt distribute the load and provide stability. An interior sleeve and mesh pocket keep valuables organized. Available in storm gray, the backpack costs $299.99.
