Sleeve length was ok, but very tight on fore arms with one layer underneath and and even pretty tight with bare arms / t-shirt only. Also a little tight across shoulders for my liking, I'm not sure if it was the sleeves of the shoulders but I herd some straining as I struggled the M on. Some of which is personal preference and if you envisage ever having any layer(s) underneath. I do like my cycling tops to be close fitting but not tight tight.
