PLEASE create a women's version of these pants. I tried ordering a small and they were absolutely huge on me. I don't see any women's pants made with the stretch fabric.

what is the weight of the pant with the bib attachment compared to the weight without the bib attachment?

I have had the Rondonnee ski pant for the last decade and am finally looking to get a new pair of ski pants. Can you compare the Alpinist to the Rondonnee for skiing.

I skied all of the spring of 2011 in the Alpinist Pant and it was basically the perfect pant for touring deep in the Colorado Rockies, Southern Sierras and Tetons! The breathability, zipper/venting, and overall functionality made for a comfortable experience in some pretty wild places.
