Last season, I purchased a Mountain Hardwear Windstopper Tech Jacket. As a lightweight jacket, it was truly outstanding in every category. I could not wait to get the matching pant pants. This season I did and here is my conclusion, it is worth the investment. Perfect example, recently I went skiing in upper 20F and a brisk wind. My legs were nice and comfortable, even on the lift chair. My laying method: Icebreaker next to skin leggings (200 weight), WindStopper Tech Pant and Tenacity Gore-Tex shell pant. Even walking around with out the shell pant, I was fine. Honestly, in the last three years, I changes over to Mountain Hardwear products, and they have not fail me yet. I strongly advise getting the WindStopper Products.
