First of all: DEATH TO THE MG LOGO!! Who the hell came up with that, anyway?!
Secondly, I actually just received the gloves I ordered, and I got a small, which is normally what I wear in gloves. When I pulled them out of the package I actually thought 'holy hell, are these children's gloves?!' they were so small. They were very tight when I first put them on---but, they do stretch out I've found, and pretty quickly. They were almost uncomfortable to wear at first, and now after a few short poling sessions with them on they aren't bad at all. Quite snug, but at least that means my hands won't slide around in them.
However, I think they're a little short at the bottom, and that might be why I'm having trouble with spins while I'm wearing them. When I spin, or even just walk around the pole while holding onto it, the bottom of the gloves tends to bunch up, so I don't get the kind of momentum I want because the glove sort of arrests all momentum mid-spin. I'm thinking this is because the gloves might be a tad too small.
They seem to run pretty small--I probably should have gotten a medium. I bet you would be fine with a small. They're not that expensive--I would probably just order a small if I were you, and see if those don't work a little better. I'm contemplating getting a medium, just to see if they go down a little farther and don't mess up my spins.
They do add a nice bit of grip on holds, though, and I can still slide down the pole with them on, which is a big improvement over just wearing liquid chalk. I tried sliding down the pole once with liquid chalk on my hands and it was so damn ugly--I'd jerk almost to a halt every few inches or so. I looked like a manual shift car with a newb behind the wheel. 😲
