Waterproof and Breatheable
Just wore these pants across the Bogong High Plains in the Vic Alps. Wind was 129km/h, blowing people off their feet, temperature -2 with wind chill factor, horizontal sleet or hail and then heavy rain (HEAVY rain!). I stayed bone dry during the 4 hour hike.
The wind was from behind and blew the zipper flaps forward, but no water came in, nor did I build up a sweat. The pants were still beading after 4 hours of that. Highly recommended.
