Familiarity: I've put it through the wringer
This Goretex pant held up to some gnarly, wet conditions recently on a stormy mountain in the east. Stood up to hours of rain, dry on the inside (thanks to strategic thigh venting zips and fabric breathability) and kept the wet on the outside. True story:
"“The BL Pro Bib's got put to the test this weekend - I did my AIARE 1 course [avalanche hazard management class] on Mt Washington in NH and spent two days touring in them. The second day was 6 hours of hard skin/ski charging in the pouring rain and not only did my legs stay dry but they kept the sweat to a minimum with the dual thigh vents.
Super happy with them and going to be using them a whole bunch more this season and many to come."
