I didn't find a glove to try on, I just measured around my palm.

When i measure around the fat part of my thumb, I get 9" or "Large".
I'll try to find some real 370s to try on. Hmm, maybe I should get some Medium and some Large, then donate the poor fits to Dave and Trish to add to the raffle prizes.
