Gore is known for their quality products and this is no exception. The knickers are well made and durable, but the sizing is a wee bit wonky. I'm 6' - ish 175 lbs, and the medium was far too tight for me. Plus the straps are made of a slightly rougher material, so prolonged tight straps caused rubbing. A large fit just right!
This 3/4 bib tights are about perfect for me on rides in cooler temps. I have used them into the high 40's and they have been warm enough, but not to the point of over heating when the temp climbs into the low 60's. The padding is very comfortable, as well as the fit of the tights.
