Built for Competition
Assassins were formulated with the unique needs of athletes in mind, and unlike sleeves from other companies, are much more than a re-purposed medical knee support.

The result is a pair of knee sleeves that are suitable for the most grueling workouts, lifting events, and obstacle course races - yet comfortable enough for the weekend warrior.
