Always US-made, and tried and tested in the great American outdoors, Epperson Mountaineering make some of our favourite back packs and bags. For SS15, Epperson's collection is refined still further to provide robust functionality that has its own unique style.

Our picks:

Opumo-Epperson-Mountaineering-Navy-Large-Climb-Backpack

Navy Large Climb Pack

A high capacity back pack, designed both for weekend expeditions and your worldwide travels. The bag is constructed from 1000 denier Cordura nylon, treated to be water repellent. A climbing-spec carabiner is used to provide easy-access closure, an addition made after Epperson Mountaineering's own Mino Makanishi used an original design on his personal expeditions. Four external pockets store electronic necessities.

Opumo-Epperson-Mountaineering-Black-Leather-Patch-Daypack-Backpack

Black Leather Patch Day Pack

A classy update on the 1970s back pack, in Cordura nylon so that the bag is scuff and abrasion resistant, whether your Day Pack is on a forest hiking trail, or navigating the daily urban jungle. Robust YKK zips enclose a 24 litre main compartment. Loops and straps, including those to carry extra bits and pieces, are in military grade webbing.

Opumo-Epperson-Mountaineering-Clay-Orange-Large-Climb-Tote

Clay Orange Large Climb Tote

Epperson's mountain expertise distilled into a tote bag. Whether yours is headed for the hills, the gym or as a carry-on bag for a weekend city break, the Climb Tote is conceived to cope with whatever rough and tumble you can throw at it. Cordura nylon protects your essentials. Handles constructed from nylon webbing have loops for added utility.
