Familiarity: I've put it through the wringer
I bought these so that I wouldn't have to use as much sunscreen while bike touring- so that it would be easier to clean up at the end of the day when wild camping. I used them for 2 summers of bike touring. When I went to the dermatologist this past fall 11 out of 13 pre cancerous spots that I had burned off were all on my arms from just below the cuff of my shirt to my wrists- the area covered and I thought protected by the 50 SPF sun sleeves. It was great to be able to get them wet on really hot days for that cooling evaporative effect but as far as I can tell they offer no SPF protection. My cycling shirt, shorts, bike gloves and use of sunscreen protected the rest of my body, but I felt that the SPF claim by Louis Garneau was misleading and dangerous.
