I use this product for ski touring, mtn. biking. I bought this jacket thinking it was similar to the Camber jacket that I had been using and enjoying....but had really overused, and needed a replacement. However, I found the sizing to be different significantly. I am 6'-1", 165, and fit.....usually plenty safe bet for a medium......however, a medium is NOT the right call for this unless you are purely spring weathering it. The medium is too tight, and won't let you layer well for Winter. Other reviewers seem to have different opinion on sizing. There is no insulation for this jacket at all....purely a weatherproofing layer. It is light and very durable and typical good OR product....but order up a size and know you're gonna have to layer underneath.

Going for a hike, after a run, around the campfire--this is the go anywhere do anything soft-shell. It looks good and performs great. I'm 5'7" and 175lbs. the Lg. fits great. The exterior is tough enough to handle wear & tear and the inside is fleece-like--warm and soft. This is my go-to jacket for any use.

i used this while climbing Rainier. It worked quite well and is bombproof!

The Cirque jacket is versatile. It works for me on cool morning trips to yoga or on snow shoe trips. It's good to have technical jacket that has a tough finish, doesn't need to be babied and is pretty waterproof. At the same time there's a soft interior fleece that feels great next to the skin or fits easily over a base layer. There's plenty of roomy pockets including an interior zippered pocket with a media cord port. The sleeves are a looser fit which means you can put it over a layer without having your sleeves pulled up to your elbows.
