Pearl Izumi

Sun Knee Sleeves

Pearl Izumi Sun Knee Sleeves deliver high-coverage UV defense and sweat-activated cooling for cyclists who want protection on hot road, gravel, and trail rides without switching to full tights. Built from ELITE Transfer fabric with integrated Ice-fil technology, these lightweight knee sleeves increase their cooling effect as perspiration rises, helping manage skin temperature when the sun is strong and the pace is steady.

Designed to pull on quickly and stay comfortable over long miles, the slip-on fit works over or under cycling shorts and trail pants, while BioViz reflective detailing adds practical visibility for early starts, late finishes, and shaded routes.

• UPF 50+ sun protection - rated UV protection that remains effective even when the fabric is stretched for a secure fit
• ELITE Transfer fabric with Ice-fil - sweat-activated cooling effect to help reduce heat buildup during warm-weather riding
• In-R-Cool technology - supports moisture management as conditions heat up
• Slip-on knee sleeve design - easy on/off layering over or under kit for road, gravel, and MTB use
• BioViz reflective elements - visibility from up to 100 meters for added awareness in low-light conditions
• 93% polyester / 7% LYCRA elastane - stretch-and-recovery blend for close-to-skin comfort and mobility
• Pedal to Zero - riding 7 miles / 11 kilometers offsets the climate impact of this garment
