Mares UK agent, Blandford, Tel (01923) 801572, should be able to tell you. If you have any problems getting hold of them in the UK, let me know. I'll be glad to get you a pair here in Sweden and post them to you (they don't weigh much, so the postage shouldn't cost too much) if you let me know which size you need. Mine are medium and I have smallish hands and feet (shoe size 8, if that's anything to go by). The mitts are far better than any others I've seen – very warm and supple (easy to put on and take off and you can do anything you need to do with them on).
