Bought XLs, the left glove fits well and the right glove is way smaller, can barely fit my hand in, rendering the gloves totally uncomfortable and pretty much useless. And I know my hands are not completely different sizes.
I ordered two different pairs of gloves from Auclair, thinking they would be good quality. The other pair is off too. Clearly Auclair has some pretty glaring quality control issues in their factories, wherever they are being made now.
Based on this experience, I would not recommend this brand to anyone.
