I used these in combination with bib shorts on cold days. How about them for spring, autumn, and winter? I think they are excellent, as they don't get too hot or slip down. I haven't counted the number of times I've used them exactly, but I think it was about 10 times at most. There are no holes or frays, but there is some slight damage to the reflector part of one leg, so I'm selling them at a low price. I don't have a record of it, but I think it was around 15,000 yen... I think. Size 1 (M-L)
