Reviews Summary

Customers say these knee sleeves provide excellent support and stability for heavy lifting, particularly squats. Many appreciate the grippy material that prevents sliding during workouts and keeps the sleeves securely in place. Users report increased confidence and performance, with some noting improved lifting capacity. The sleeves are praised for their durable, heavy-duty construction and quality materials. However, sizing is frequently mentioned as challenging - many recommend ordering a size up as they run small and can be difficult to get over larger calves. Several customers experienced fitting issues despite following the sizing chart. Once properly fitted, users find them comfortable for extended workouts and effective for knee support.

I use these on light
I use these on light squat and leg accessory days. These are also tight enough to stay upright on me calves for shin protection on deadlifts.
