Easy to get on and off and comfortable enough for a full day of pedaling, the Dakine Slayer Knee Sleeves have the perfect low-profile padding for long, hot days on the trail. They're constructed from lightweight DK Impact foam that stays flexible when you're pedaling and pumping down the trail, but hardens upon impact to absorb the energy of a crash. This makes them a great choice for riders seeking substantial protection without any excess bulk.
