Cold, wet, and muddy. This glove was designed to keep the back of your hand warm yet allow the palms to breath on the bars. The Basics for Cyclocross racing. Breathable palms and weather resistant back. This glove is a toned down version of the Premium Cyclocross Glove. Good for cold, wet weather and great for helping manage your body heat.
I have used this glove now a few times and I will have to say I really love it. My hands get cold relatively easily and take a while to warm up. The palms of the gloves do breathe nicely and help regulate your hand temperature. The times I used this glove the temperature has ranged from 35F to 50F. The sweet spot for this glove is right around 45F.
If you have ever tried the original Glacier cycling gloves these are very different. The original gloves did not breathe very well and I felt it would take awhile for my hands to warm up. My hands would then sweat and get cold. These gloves are much thinner and breathe nicely. I would highly recommend these gloves for cool weather racing conditions.
