Very personal choice indeed. In the last couple of years I have tried some no-brand warmers from Boone's shop, some Capo Forma arm warmers - and in the end went back to Assos. I tend to like Assos best because they are shaped to fit well when you ride, like most of their clothing. These warmers have an anatomical elbow bend so that the fabric does not create a crease when you ride and your elbows are bent - while most other arm warmers do. And they are really warm. Capo has nice fabric too, keeps you warm - but they stretched out in the washing machine so after a few weeks they did not hold too well. Try a few in the shop and see what feels best.
