I have used these pants in the driving rain twice. They kept me perfectly dry. I am 5'7 with long legs and the size small were long enough to cover my shoes and keep the rain out of them. There was plenty of room to layer cycling shorts or tights underneath. The velcro tabs at the calves make them very adjustable.
These are great. Sturdy and comfortable. Did take a couple rides to get used to a weatherproof fit tailored for cycling (I previously was only using a hiking pant - worked fine, but time for an upgrade after 4 years). My only gripe is the mesh pockets. They catch on everything and it's just kind of overkill for the situation. Understandable why they are there.. Just not needed in my mind. Overall - great great great and would recommend!
I would use this product in a heavy shower. However, rain missed me the last trip and I didn't put them on. I am so unhappy about not having to cycle in the mud and fight the blowing branches but we all have our crosses to bear. I'm sure next time I will be rewarded. lol. I am a size 10 jean, 5'4 and got the medium size. It fits perfectly. My daughter is a few pounds less but 5'7 and I got her a small. Too tight. Returned for a medium and it fits her perfectly. Would buy this product again. It's well made.
I like these rainpants a lot. They are of good quality and have nice features zippered pockets - which I find helpful and not always available in a rainpant, zippered ankles and velcro to pull pant closer at the lower leg, and reflective strip around the pant below the knee. I can't imagine that I'll ever need to remove the bottom part of rainpant leg, but I can if I want.
These run large. I'm generally a small, but find that even the x-small are slightly too big around the legs and waist. If you're unsure, order your usual size PLUS one that is a size smaller, and then send the one that doesn't fit back.
I returned these as they were so big, I could get two of me in. I felt even with a smaller size there was just too much material in the but and legs to ever be comfortable as a rain pant while riding longer rides.
I use these pants for my winter bike commute, and they've worked out perfectly. It's my first year of winter bike commuting, and they've made this transition easy for me. I haven't yet tried the zip-off bottoms yet - I'll have to wait until summer to see if I'll bother with that on the ever-present rainy warm days of NW summer.
