RockTape Assassins Knee Sleeves - Pair

Rocktape Assassins Knee Sleeves - 5MM - Pair

Several factors help set Rocktape’s new Assassins apart from many standard knee sleeves on the market. First is quality construction; Assassins are made from a synthetic fabric shell bonded to SBR neoprene (5MM thick) and secured with double-mauser stitching. Second, these sleeves are designed for the high-performance athlete training at the competition level—with extended length for greater stability and tracking of the knee through a wide range of functional athletic movements (including weightlifting, where lateral stability is critical). Third, it’s the graphics—few sleeves have a design that stands out quite like the Assassins. And finally, there’s the value, as all Rocktape sleeves are sold in pairs and packaged with a one-year warranty.

Beneficial for athletes of all sizes and skill levels, Rocktape Assassins effectively compress the vastus medialis (a part of the quad muscle critical to knee extension) just above the patella. This design, combined with heat-sealing seams, ensures optimal comfort, contouring, and blood flow. Wearing a pair of Assassins can result in better performance today and reduced knee pain tomorrow.

Most in-stock orders made through Rogue Fitness before 3pm will ship the same day. You can follow the progress of your order online using the Rogue Shipping Tracker.

*The vastus medialis muscle is one of four quadriceps muscles. It is located on the inner part of the front of the thigh. The lowest part of the vastus medialis, called the vastus medialis oblique (VMO), achieves its maximum contraction during full extension. The VMO helps to stabilize the patella and allow it to track properly.

RockTape Assassins Knee Sleeves - Pair is rated 4.5 out of 5 by 35.
Rated 5 out of 5 by from Great Product I bought these about a month ago to wear on quad training days. I've been lifting for about 1 1/2 years and recently my knees were feeling less stable when performing squats, leg extensions and weighted walking lunges due to the increased weight I had been lifting. The first time I used these I noticed an immediate difference in my knee stability as well as decreased soreness in my knees after lifting. I am much more confident in my lifting on quad day and have been able to increase the amount of my lifts.

Rated 5 out of 5 by from Best Support Ever I’ve never used knee sleeves before. As I age, it’s apparent that my knees are not the best doing crossfit. So, after a year of squats and wallballs I decided it was time. I’m so glad I chose theses sleeves. Feel so secure in my squatting. Thanks

Rated 5 out of 5 by from Why didn’t I buy these months ago?!!! I began running 18 months ago. I am overweight and 53 years old. My left knee began hurting so bad that I had to stop. Dr. Prescribed anti inflammatory, and told me I had arthritis and that running may not be my sport. My trainer told me to try these, specifically your brand. The relief was almost immediate!!! My workouts are on point and I am even running some again! THANK YOU!

Rated 5 out of 5 by from Very nice fit and support Have been using these for about a month, 4-5 times per week. Sleeves for the most part keep you warm with some level of support. These sleeves give you a bit more support because they are a bit longer and the construction helps with knee stability. I wear a so KT on the knee under the sleeve for additional support when squatting.

Rated 5 out of 5 by from Great product I bought these a year ago and use them about 2-3x a week I love them they have helped a lot the only down side is from all the use they are starting to tear and get stretched out. Overall really impressed with these. The ones I bought before from a sporting goods store only lasted 4 months
