MALEROARDS is a manufacturer of cycling packs, and this is a cycling, trail running, and running pack, bag, and backpack. The pack itself is small and lightweight, but it has a lot of storage and is designed to hold most items. The capacity is 10L to 12L. The pack has a gusset to adjust the capacity, and you can easily adjust the capacity inside the pack with a zipper. It also comes with a dedicated pack cover, a helmet attachment net stored at the bottom of the pack, a dedicated slit for a hydration tube, a small pocket on the shoulder strap, and an emergency whistle (unused) on the chest buckle. It's a used item that has been used about twice, but it's in good condition, and there are no tears or stains. It's almost like new. Thank you. #★Thank you.
