These are my favorite gloves for kite boarding in the winter. I have been using them for a few months now and have been really happy with them. Pre Curved fingers are 100% the way to go if you are using this for kiteboarding.
Great manufacturing quality and seems to be well built. Mine are showing pretty much no signs of wear at this point.
I really like the velco strap around the wrist. My old gloves didn't have that and they were always filling with water, and I would always have to re adjust my wetsuit cuff to get it water tight. These ones just velcro shut and your good to go.
Sizing seems normal. I always wear a XL glove and the XL was the correct size for me in this glove as well.
