The Outdoor Research Uberlayer is a well constructed, highly breathable jacket that, along with the Nano-Air, is changing how we think about layering systems. The Polartec Alpha insulation helps regulate temperature whether you're charging hard up the hill or stopped for a break. Additionally, the stretchy shell and liner fabrics create great mobility and breathe very well. We enjoyed climbing in it on chilly days because it moves well and has many climber friendly features.
The Uberlayer is a good bit heavier a than our Top Pick for Breathability, the Patagonia Nano-Air Hoody. We love both of these jackets for charging hard, but feel the Nano-Air is both higher performing and more mobile. The Uberlayer has a thicker, tougher shell though, and we feel that it will hold up to abrasion much longer, potentially making it a better value.
Outdoor Research is phasing out the Uberlayer in favor of their new Ascendant Hoody. You can still snatch up the Uberlayer at a discount if it's calling your name. Otherwise, check out the Ascendant Hoody as an affordable alternative!
