The Arc'teryx Nuclei Hoody is a lightweight, compact, trim-fitting belay jacket with a high warmth to weight ratio.

- CampSaver.com

The mornings and nights during your week-long climbing trip to Vedauwoo can be chilly when you aren't sending it. Throw on the Arc'teryx Men's Nuclei Hooded Insulated Jacket to maximize your warmth without being weighed down. The Aieretica lining and face fabric is tightly constructed and highly tenacious, which means it can take the abrasion of the sharp Vedauwoo rock if you brush up against it. The Nuclie is stuffed with Coreloft insulation, which is made with highly crimped multi-denier siliconized polyester yarn, so, basically, it is lightweight and breathable, compressible and has an excellent loft retention. You can put the Nuclie in the interior stow pocket when not in use, and you can also use the clip-in point for attaching it to a harness.
