These gloves have no sizing guide. I ordered “large” size initially (this has been comfortable with past glove purchases), but they were too tight. Then I returned them and ordered “extra large”. These did not seem any bigger. Since I am not doing much summer motorbiking, I have not bothered to return again and ask for an even bigger pair.It seems obvious to meet that a mail order company would tell customers how to choose a size, e.g. by measuring width of your hand or by running tape measure round your hand.I’ve only ridden with them once in dry conditions and they were ok, but a bit tight still. With this experience I would not buy from this company again.This is a really nice summer gloves. Gives protection but in the meantime there is a lot of airflow. Best of both worlds.My hands are finally happy.It's a great quality as Oxford products generally.Bought these to replace my old summer gloves. Seem well made, comfortable, reasonably cool, seem to offer good protection.Well they look very well made and very comfortableReally nice design. Fit well
