I have owned these bibs for over two seasons and have been very impressed, for two reasons: These bibs are incredibly durable and they work in a variety of temperatures. I give these bibs the highest rating. The bibs took some time to get used to, but after a few tumbles in some of the "deep stuff" you are excited to have the extra protection. I also find that it keeps me warmer, as it prevents in air flow from creeping in at the waist line.
