I live in the Pacific Northwest where the average high temperature is 60 degrees and lower for 7 months out of the year, yet the average low only goes below 40 degrees 4 months out of the year. I was looking for a bib short that could be used when the temperature was too low to comfortably use summer shorts. As it drizzles and rains here for much of the year, I was also looking for something that shed water well in case I got caught out in showery weather. These bibs fit the bill. Matched with the Nanoflex knee or leg warmers, these shorts give me a lot of flexibility in getting the right level of insulation for the conditions.
