The North Face Terra Bum Bag, 3L, Asphalt Grey/Black

When you only need a few essentials on a short day hike, the Terra three-litre bum bag keeps things neatly stashed away. The main compartment holds larger items such as a water bottle, phone, keys and wallet, while the extra pockets on the inside and outside offer easy on-the-fly access to smaller valuables.

To keep things comfortable as you push through the trail, the webbing waist strap is adjustable, and the plush back panel is padded. What's more, the bottom compresses when the pack's not full, making it even easier to carry around and hold bulkier items.
