The Terra 3-Litre Bum Bag is perfect for daytime adventures and does not need to carry so many things. The main compartment holds larger items such as a water bottle, phone, keys and wallet, while extra compartments on the inside and outside make it easy to access smaller valuables on the go. To sit comfortably as you make your way along the trails, the waist strap is adjustable and the back panel is padded. In addition, the bottom is compressible when the backpack is not full, making it even easier to carry and store bulkier items.
