Most other MTB gloves come up a bit tight on my thumb. On long rides, that's uncomfortable. I've been wearing Fox racing gloves for over a decade and they're the only light full finger gloves I've used that fit my hand perfectly.
Light, thin, grippy, affordable. I have worn these almost exclusively for the last three months and have washed them several times and they are still in good shape. Not a lot of material, which means it dries quickly. I will be buying more.
