DMM, based in Llanberis, Wales, have been a reliable producer of climbing and mountaineering equipment for over thirty years, and they are now actually becoming a fairly decent knowledge source for climbers of all levels. The founding directors, Denny Moorhouse, Richard Cuthbertson, Paul Simkiss, and Fred Hall, agreed that they wanted to make the best possible equipment at the best price, and this has been the influence of their innovative and often unique designs of carabiners, quickdraws, belay devices, helmets, harnesses, nuts, and cams. But DMM now also offer a Knowledge section on their website, where you can learn how to maintain your gear and also discover handy tips and tricks to use in your climbing. Truly committed to giving you the most of their gear.
