About the brand

People wearing and using Rab gear are hanging on a snow mountain and enjoying interesting snow views and a drink.

Rab specialise in making rugged, high-performance mountain clothing and equipment. Created to give you ultimate freedom, protection and comfort, we use cutting edge materials as well as time-tested ones such as premium quality European down.  Nothing fancy or over-engineered – just honest, hard-working pieces that you’d rather repair than replace. 


More than thirty years since our founding, we continue to find inspiration in the untamed spirit of the mountains where we climb, the friendships we forge on the peak and our enduring mission: to awaken the climber in everyone and equip them for the ascent.
