I purchased these gloves and have used them on 30-40 degree temperature rides in central Kentucky. They were warm but unfortunately my hands get very sweaty in them. As such I have switched to a more breathable pair of gloves. Durability has been excellent thus far.
I bought these for Mt .Biking on coldwet rides, the fit is good however the seam that runs down the thumb is in a bad spot rubbing on the inside of thumb. They may be more comfortable for road riding given the different hand position.
I gave these gloves to my husband for Christmas this year and he was so excited to get them. He rides his bike all year and in Pa, that means all kinds of weather. Hes used them and said that they are perfect!
