ATOM PACKS MO EP50 £265

The Mo is an ultralight, built-to-order pack made in the Lake District that allows you to select your preferred back length, hipbelt size, materials, pocket configuration and even colours. It’s rugged and roomy, with a handy stretch shoulder pocket and a top Y-strap for stowing a sleeping mat or tent. The simple but effective harness and back panel balance low weight with comfort and load stability.

VERDICT Pound-for-pound, this has to be the toughest pack around. A great choice for fast and light backpackers, offering far more than most ultralight rivals in terms of practicality and durability.
