The lightweight and cool Sun Sleeve provides arm protection against the sun's ultraviolet rays. Pearl Izumi Sun Sleeves now have In-R-Cool® technology to reflect the Sun's rays for optimal cooling. Summer weight arm warmers or sun sleeves in this case are exploding in popularity thanks to the sun protection, compression and cooling benefits they offer.
The Pearl Izumi sun Sleeves are designed to cover and protect the arms from the sun in warm weather. They have somewhat of a compression fit that works to reduce muscle vibration helping to keep the arms fresh during exercise. The Pearl Sun sleeves deliver UPF 40+ sun protection eliminating sun damage and reducing the need for expensive and messy sun lotion.
I live in Florida and deal with very intense sun and high humidity. I also have skin cancer. So I should have gotten these things years ago. Anyway they are fantastic. Very light, nice fit, and the cooling effect is amazing. They are like air conditioners for your arms.
Pros: comfort, sun protection
