Have a pair of these sleeves with me here on a month long visit to Perth / Fremantle Australia in the blazing summer sunshine. Been here for about a month and hired a bicycle for self transport. These have been great for having in my pack and sliding on for a ride or beach time sun protection. Sometimes a little warm in the blazing sun, but then so is having the sun glaring down on the bare skin. I recommend them!
