RockTape's Assassins Compression Knee Support Sleeves are the ultimate weapon for workout domination. Assassins will keep you ahead of the game by keeping your knees supported and protected while slaying reps and crushing WODs. Assassins can be used in a variety of sports and fitness pursuits, including weightlifting, high-intensity interval training, obstacle course racing, running, cycling and other functional fitness endeavors. Taller than standard sleeves and carefully constructed with a unique organic design, Assassins support the knee and compress the vastus medals oblique (VMO) at its insertion point above the patella. This helps ensure proper stability and tracking of the knee and can often dramatically reduce non-specific knee pain, particularly during squats. The extra-tall design also keeps sleeves in place, preventing excess slippage and shifting during workouts, a common complaint of competing sleeves. Made with synthetic fabric shell bonded to SBR neoprene and secured via double-mauser stitching. It has durable yet flexible front panels and 4-way stretch lycra side panels. Choose from 5mm or 7mm thickness. Please Note Assassins start very snug and can take a few sessions to break in. If you are between two sizes, it is recommended to order the next size up.
