Rab Xiom Pants are very lightweight overtrousers at just 267g (size L), making them ideal for those who want to travel light. They’re made from 3-layer Pertex Shield – an excellent fabric for trousers as it has no mesh ling to snag, yet it controls condensation better than a 2-layer or 2.5-layer fabric. The fabric boasts top-end waterproofness and breathability too. In terms of features the trousers are somewhat less inspiring though. The waist is a basic elasticated design with elasticated drawcord, so you don’t get a zipped fly, braces, or belt loops. The legs are slightly articulated for a closer fit and have thigh-length zips to allow the trousers to easily fit over boots. There are double zip pulls so you can vent the thigh if needed, and the zips are the more water-resistant variety, but you only get a small internal flap to keep any leaks at bay. There’s a drawcord at the ankle cuff, but no additional tabs to shape this area and also no reinforcement. The Rab Xiom Pant is a great option for lightweight hillwalking and backpacking if you rate weight and fabric above the additional features that some other trousers boast.
Material 3-layer Pertex Shield
Men’s sizes S-XXL
Women’s sizes 8-16
Weight 267g (size L)
You’re getting a great fabric and a great weight here, but the Rab Xiom Pant’s features are less impressive, although they’re still more than adequate for most hillwalkers and backpackers.
