I love these sleeves. They work better than anything I could have expected. My skin burns through spf75 even with frequent application. I've never burned through these sleeves even on my longest days on the bike. They do not make you warm and for an added perk you can soak them in water and put them on wet for extra cooling.
The only problem I have had with them is that my arms are smaller than the average arm so I have trouble keeping them up around my biceps. If you are not a petite female this should not be an issue.
