This is an initial review with a long term review to follow. Sizing was based on their suggestion on their website; http://www.7protection.com
I am 6 feet tall and about 215lbs, the XL is a great fit. At the top and bottom there is a rubberized strip on the inside of the elastic band that is comfortable and has kept these very secure with no noticeable movement down my legs.
The wrap around the upper and lower leg is very light and breathable. The foam protection at first seems hard but softens quickly and conforms to the shape of my knee perfectly.
Through the first few rides, I forgot they were there. Which is a credit to the comfort I found with these. My rides so far this winter haven’t been that long, when Spring is closer I will be interested if the result changes with longer rides. For now, I like them a lot and enjoy their low profile and love the look.
