I was inspired to have this topic by another related topic thread here.

Do folks here wear their cycling gloves quite tight?

I don't because I don't like it when my fingers swell in hot weather and I have to tug off my gloves harder to get them off. I want my fingers to have circulating blood.

I used to buy and wear the exact size for me. ie. X-Small. But now I move up half a size if I can/if available.
