My hand is a big medium, once I got them on it was a slightly small fit, however the main problem was getting them on the hole is tiny and difficult to get on.
They're not tough, one crash on a smooth berm and there's 2 holes

Nice gloves. Size up cause they run small.

Full disclosure: I am supported by the Chromag grassroots program, and these are the best fitting, most comfortable gloves I have ever used. The palm fits perfectly and there’s enough room in the fingers that I don’t pop through the ends. They are thin, but still durable, and the colour options are fun (although I only have charcoal and black…) I always wear gloves, and these have been my go-to for riding all season.

These are great low-profile gloves for a little extra grip and protection. What I was most impressed by is how well they work with a touchscreen compared to other "touchscreen compatible" gloves I have worn in the past.

The gloves fit great and feel great but they ripped after 2 rides, no falls, the stitching gave way down by the thumb.

Best gloves for as close to gloveless feel! I usually don’t wear gloves but on hot summers days when my hands get sweaty I need to! These gloves fit tight with out any movement or shuffling about in the hands.

Favorite thin gloves I've ever worn. Closest to no glove feel. So far very durable too.

Got these gloves recently in the bluebird, absolutely love them. They feel like a second skin, and the grip on the palms is fantastic without making you feel like you get stuck to every surface. Just a perfect glove for all kinds of riding, even in the wet and cold I am impressed with these: thanks, chromag!

Regarding fit, I will say that I got the large only because I usually get large gloves (the size chart made me think I could fit into any size) and they fit bang on. Like I said: second skin. If you want something that will give you a little breathing room I would recommend going up a size from your usual.
