I bought a pair of these tights late last fall. In fact so late I was unable to use them because of snow and gravel on the shoulders of the roads and on the bike paths in Eastern Washington. Early this spring I put them to them to good use. They are well designed for temperatures that range between 32 degreesF and up to about 50 degrees F. Above those temps they are to warm. They seem to be well made but do run on the small size. I sized up one and was fine. They are a little more money but well worth the cost because they are the first bibtights I have owned that will keep yuou warm at the very low end of my riding temperature range.
The Sorpasso 2 is an extremely well made bibtight, infinitely comfortable, and keeps me warm without being stifling. For Americans, be sure and size up one.
