Should have tried these first!
I have tried several different types of long underwear in the past, but this is my first pair of Capilene pants. I have to say that I am very impressed and pleased with this material. The Cap-3 is lightweight, highly compressible, breathable, flexible, warm, and comfortable. They fit close to the skin, but do not constrict like tights or bunch up behind the knees or under the crotch. These pants deliver all the things, and more, that I want from my base layer.
My biggest complaint with most mid-weight base layers is that they tend to be pretty shabby at keeping in the heat when the storm sets in. However, I find myself pleasantly surprised with the Cap-3 material and its heat management abilities. When paired with a shell pant, these are all the insulation I need. Plus, the material is thin enough to fit into my tight boots along with my socks. At 510 175 lbs. I found the Medium to be a perfect fit.
These are not just expensive pajamas.
