Detail-rich and lightweight, the Altiplano Pack 20 from Montbell hides supreme technicality and high-performance behind a humble moniker. Boasting a highly useable 20-litre capacity for day hikes, the style can easily accommodate gear, food and extra layers in its main roll-top compartment, with internal and external pockets for organisation. Waterproof protection come courtesy of a seam-sealed Aqua Barrier sack, which usefully is separate and removable. Constructed from 30-denier nylon ripstop, which contributes to its minimal weight, with a reinforced bottom panel for enhanced protection. Finally, there’s a sternum strap for stabilising the load.
