Using these bike knee sun sleeves is easy. Just slip them on over your knees. They're great for cycling in the sun, providing protection and keeping you cool. When you're sweating, they'll manage moisture well to keep you comfortable.
For sizing, check the size guide carefully to find the right fit. If they're too tight, they might be uncomfortable; if too loose, they may not stay in place.
When it comes to maintenance, you can machine - wash them in cold water. Don't use bleach or fabric softeners as they can damage the fabric and reduce the sun - protection and cooling effects. Hang them to dry instead of using a dryer. This way, your sleeves will last a long time and keep performing well.
