Puma may have dubbed it Challenger, but this medium-sized duffel bag makes light work of transporting your gear. The 58L main compartment seals shut via a two-way zip, and additional zip compartments can be found at the sides, one with a shoe inlay. The webbing carry handles can be joined with the hook-and-loop closure connector, or you can sling the bag across your body. There's a D-ring on the front for attachments, which sits just above a large Puma Wordmark.
