Great piece!

  • Familiarity: I've put it through the wringer
  • Fit: Runs small
  • Size Bought: large

This is a great insulating piece from fall on. It wicks and is super breathable. The deep vent gives it a lot of versatility although it is breathable enough to seldom need it. Worn under a shell it gives a nice microclimate, but take it off and you feel the moisture escaping right through it. It's close-fitting and seams are out of the way so it is comfortable with a backpack.

Great Lightweight piece

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: M

This is my first item made by Mountain Equipment, Inc. (British gear manufacturer). I've got to say, I'm very impressed. This is very well thought out and well made. It is also the perfect weight to wear all year round. I purchased a medium - it weighs exactly 9.4oz. Very versatile:
- cool weather running
- over workout gear to and from the gym
- base layer or light mid-weight layer
- great skinning layer for the up, throw a layer on over it for the down
I plan to wear this on an upcoming climb of Pico de Orizaba in Mexico, where I'll be in temps ranging from warm to quite cold up high. I think this will serve many functions on that trip because it is such a versatile weight.
In summary, this is a very well-made piece and the attention to detail is obvious. Really impressed with the quality of this brand.
