Based in Seattle, USA, adventure apparel and gear specialists Outdoor Research (commonly just called OR) have been manufacturing excellent outdoor equipment since 1981, and I’ve always been impressed with their gear.
Most recently, I tested the Helium UL, a super-light waterproof jacket from the brand, which boxes well above its extremely svelte weight, keeping you dry and protecting you from the wind while weighing virtually nothing and taking up very little room in your backpack or running pack.
