Joe Spier wrote a review of The North Face Mammatus Bib - Women's on January 13, 2010
I bought this bib for my wife to ski & climb in. When I saw it, I wanted one. However there are features she didn't like. Fit is athletic so even an XL is tough to fit for a bell shape woman. She too thought the drop-seat wasn't large enough. I got this for a deal on sale or she would have shipped them back. They will work for skiing in light layers, but not for anything that needs an extra fleece layer due to the sizing = NF's and her shape. Use caution for the sizing, otherwise a great bib.
