I've used it once or twice and have initial impressions
Got these for nordic skiing because my wife has a pair of Crafts that work very well for her. However, these are more tuned towards biking than skiing than hers. These have different (stiffer) material in the seat and crotch than hers, but they are plenty warm enough to ski in on the coldest days.
First bib I ever bought, but they are so comfortable I'm afraid anything else would be a disappointment. I also bough a pair of shorts, but ended up sending them back because they are just not as comfortable as this bib.
