ASSOS LL.MILLE Bib Tights Size M Photo 4: There are some pills on the inside of the left knee due to rubbing. (It seems the frame bag and knee were rubbing) Photo 5: There are some pills on the sacrum area due to rubbing. Other than that, I think there are no noticeable stains or damage. Quoted from the online site below: ASSOS uses "RX Fleece HEAVY," which is used in various items and has excellent heat retention and insulation. Fine adjustments have been made, such as reducing the heat retention of the fleece in areas where heat tends to build up, such as behind the knees. The surface is treated with "ECO water repellent," which can handle sudden changes in weather. When you hear "tights," you might feel like they are constricting, but they are very soft and comfortable enough to wear all day long. The suitable temperature range for wearing is 6-14°C, which is the most comfortable temperature range for cyclists to ride in this season. Rapha.
