These P.I. sun sleeves are the best I've used so far. It's no gimmick, they really do keep you cooler than skin expose to the full summer sun, and the logo is small enough to not intrude on your team kit's summer jersey sponsors.
Great purchase. (White) I use them for everything. Bicycling, driving and even playing golf. As mentioned in another review I have cyclist arms. I am 5â€™ 11â€ and I purchased the large size. They are perfect, snug fitting and nice length
I use these sleeves for shoulder season riding when mornings are cool, but the end of the ride will be warm. They are not bulky like thermal sleeves, but still provide just enough wind protection to keep you comfortable for those times when a jacket is too much and a summer jersey is not enough.
I ride everyday around noon and 3p, so I'm in the sun. Last years (2017) model didn't seem to breathe that well, after a ride it felt like my arms were wrapped in plastic wrap. The 2018 model is much better, it breathe and wicks the sweat. But even after a LONG ride on a sunny day, it still feels good to get the sleeves off. As for sun protection, based on the pale skin after taking my watch off, the sun is still getting through the material, but the arms aren't really dark as compared when I rode without sleeves. I found that pulling the sleeves up the the edge of your riding shirt sleeve, keeps the arm from overheating vs. pulling up to the armpits..
I have always worn sun sleeves, and only stuff them in my jersey when it gets beyond hot. For riders that spend 20 to 30-plus hours a month in the saddle, do yourself a favor and cover your arms with any brand of sun sleeve that has a good SPF rating. These Pearl Izumi sun sleeves are constructed of a nice light material that does the job. There's always a funny, thin ring of a sun tan between my gloves and the wrist-end of the sun sleeves, so I can see that they are working, and doing what I need them to do.
Not really a complaint, but the most recent pair I purchased are actually a deep-dark-blue color, and not the color black like my older P.I. sun sleeves.
My most recent pair is my third pair. I'd say they last two years before they start to get less snug but still perfectly functional. I ride in Hawaii where it is always hot and sunny so I wear these on every ride. Other brands don't use silicone arm grippers to hold them up or they are cut too large for my cyclist arms (I'm looking at you Spesh). I'm 6' 3" and I wear size large but maybe the XL would work too. I love these bright white snug arm covers.
I have many different types of arm SPF protectors, but this one has to be one of the heaviest in terms of material. Most of them are very light and do the job. The Pearl Izumi provides 50+ but you will sweat quite a bit with them at temps above 75degF. I do enjoy them for cool sunning days. They do provide minimal warmth and sun protection. I am 5'3" 130lb and find them to fit very well without any marks left on my arms after removing them.
These fit well with a left and right sleeve. They are a little on the long side, but better than too short, They are a good sunscreen and wick well. I live in the desert where it is really hot. It's true that if you get them wet they will be very cool to your skin until they dry - which is within a mile of starting a ride where I live. After that, they do wick away sweat which keeps you cooler and dry. I like that they are SPF 50 - I'd rather wear these then have a sunscreen film. That said - when it's really hot (and I mean 90+ degrees at 6am and 105+ by 10:00, I am about 60/40 wearing these - and less so on a day where the humidity is about 70%.
