I'd never heard of ARC ON until I came across them in store. I was originally looking to buy gauntlets by another well known brand beginning with an A. After trying various brands I spotted these, tried them on and the decision was made instantly. They are exceptionally comfortable, with great feedback through the fingers and palm. they fit my hand perfectly and require absolutely no breaking in. They've molded to my hands after a ride and now feel even better. Sizing seems a bit off, I'm a medium in everything, ARC ON fitting chart says medium but I could get them on, large is perfect.
