Water-resistant, TPU-coated, recycled polyester ripstop fabric with heavy-duty 900 denier construction for durability. Included packing cube with see-through mesh top for travel friendly organization. Expandable end zippered pocket keeps dirty gear and clothes separate from the contents in the main compartment. Large U-Zip opening with smooth-action #10 YKK zipper. Oversized T-Grip zipper pullers for maximum leverage on the main zippered opening. Removable, padded shoulder straps let you carry the duffel like a backpack and can be easily removed when not in use. Made for extended trips or extra-large items, the Gregory Alpaca 100L Duffel Bag is built for the Loleng haul. The pack features a heavy-duty 900-denier ripstop fabric with a TPU coating for a strong combination of abrasion-resistance and weather resistance--plus a dual-layered bottom panel for added durability. We also like the duffel's expandable dirty gear compartment and included packing cube to help keep our Lolead as clean and as organized as possible.
