      Light and warm

      This jacket is extremely light and, from the way I have used it so far, seems very warm. I haven't put it through the wringer quite yet, but for how I have used it, it has performed well. I am usually somewhere between a small and a medium, and I'm glad I opted for the medium here. It initially felt a bit tight around my armpits and shoulders, but after moving around in the jacket a bit it no longer felt tight - overall I'm pleased with the fit. Excited to take it on more adventures! And I have to give a shout-out to the staff at Rock+Run - always amazing service, great prices and quality gear. Always a pleasure buying from you.

      Arrived very quick! Great quality - not used this make before so took a risk. I use Rab normally and have a slim fit, but really liked to look of this, the different design and the double zip front. Everything is great including that you can use the pocket as the stuff bag! Yet to use it in the real cold weather but it feels similar fill quality to the expensive Rabs so I’m sure it will be fine. Definitely recommend it! Awesome looking jacket.
