Superb mtn bike pant

EXCELLENT pant that fits true to size. I am 5'7" and weigh 170 lbs. 34 waist which is a size large fits perfectly.
Excellent streamline fit including through the thighs. I have larger than normal thighs I believe and the fit was perfect. I recently wore the pant for a 2 hour ride in 35 degree temperature and found them to be warm but not too warm. As well,l rode through some streams and they repelled the water perfectly. Pant is flat out excellent and will be buying another color ( I presently have the black pair)

Best bike pants

Been looking for bike pants to commute In for ages it seems that are waterproof and wind proof, These pants are amazing, out of the box fit was great was able to get dull depth squat in them no issues of binding, rode with them on today in 43 degree F weather and were decently warm but any colder would put thermals on under. Tested the fit with my Arcteryx RHO AR bottoms on and absolutely no issues, waist still had enough room and no bunching, should be set for when it starts freezing. I like the added thigh vent zips as these pants are pretty thin in so could definitely use them as a summer rain pant. Overall very pleased with them and the raven is a a good looking color and nice slim fit that tapers at the legs, no issues getting stuck on the cranks but I also run a e13 chain guide and bash guard with only one sprocket you front so pants haven’t been an issue before. Will be ordering the blue colored ones here soon. Also though slim cut there’s plenty of room for thighs and glutes if you are one to do Oly and have bigger thighs or buns, belt loops really give good purchase on pants and pants don’t drop when you bend over or squat.

Very comfortable

Super high quality and fit perfect. I’m exactly 6’ tall and weigh 200 lbs, normally wear a size 34 / 32 in most jean brands (sometimes 33 waist) and size Large worked perfect. Would prefer the back pockets to be a little larger, that’s my only minor complaint.
