I purchased this as a replacement glove for cool weather riding. I'm very happy with it for the following reasons;
Really works well to keep hands dry and warm riding in the 40's-50's F degree
Zipper is very easy to use, and the gloves are quick to put on and remove.
I also feel as if I have very good and comfortable feel on the handlebars of my road bikes.
Although I like the snugness of a Velcro fastener on the cuff, these zippers are super convenient, and close up pretty securely.
The grippers work very well, and the durability and breathability seem very good; I do machine wash and dry them at lower heat dryer temp setting (yeah, probably not supposed to put them in the dryer), and they are holding up well. I absolutely recommend these.
Really like these gloves. Thin but quite warm and wind proof. Good down to mid 30's for me. No panel on it is un-insulated, unlike some that leave the sides of the fingers, thumb or palm. The zipper makes it super easy to remove and there's plenty of room for the fingers also.
Excellent gloves for temps around 40 degrees. As others have mentioned the zipper will take some getting used to and the lack of touch screen compatibility is a bit disappointing but the comfort and performance make up for it in my opinion. I've become a big fan of Infinium fabric and Castelli gloves so buying these was an easy decision.
This is my second pair of Castelli cycling winter gloves and it quickly became my favorite go to. The zipper adds to functionality and enhances the fit. I love Castelli gear - very functional and stylish at the same time.
They do keep the hands warm and the zippers do help with adjustable venting when hands heat up. Zippers take time to get used to and can be a little frustrating. The biggest frustration is trying to use your device with these gloves on..... NOT happening. Have to take them off when having to use my devices. I've worn worse....I've worn better, but these fit my smaller hands the best and thats a big plus.
