Nothing like trying to spray sunscreen on per ride right? Gets all over and is sticky as well as washing off less than an hour after you ride on a hot day. These fit well, wick away sweat and protect you all ride long. I own two pairs and I bought a pair for my wife who does long hikes. I was confused about size which kept me from buying these sooner, Castelli (on their website) actually sizes these by body weight. I run between 160-165 pounds and large fits great. My wife at 115 pounds is a small. I am honestly thinking of buying the leg screens though I don't mind sunscreen on my legs. If you are fair skinned these could save you from a bad burn or worse. Last point the grippers hold tight and and the sleeves should be put on BEFORE you put on a watch or ROAD ID otherwise they are annoying to put on.
If it wasn't comfortable I wouldn't wear it. Keeps me warm on 50 degree days. Knock's the wind down as advertised. Quality zipper, good rear pocket storage. I would definitely buy this item again.
