Very lightweight and somewhat warm

  • Familiarity: I've used it several times
  • Fit: True to size

I use this jacket for hiking, running, dog walks etc. It's great when I am worried I might get cold, or need to warm up before shedding some layers. It's light enough to compress into it's own pocket, but the zipper isn't set up for it (just so you know). I'd give it a higher rating, but I do wish it were warmer and I really wish the zipper did work to stuff it into itself.

Great jacket to cut the wind

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This is a great product that I am surprised is not copied by other manufacturers. It is thin, light, and soft. Cuts the wind and blocks the sun. Great for ski mountaineering during long uphill slogs to vent sweat while cutting the wind and protecting you from the sun. I no longer carry a balaclava thanks to the built in hood. In very warm conditions, I wear it over a t-shirt for sun and wind protection, then add another layer to ski back down. This jacket has become a skiing and climbing essential.

  • Fit: True to size

6'4", 220 pounds. XL fits perfectly, mostly because the sleeves are longer to accommodate the thumb holes. Perfect light precip shedding piece for when it's a bit too cold for a t-shirt in the mtns. Wore it after it got dark this weekend the descent from Mt. Buckner in the North Cascades, WA.
