I believe it was Shakespeare that first asked "5mm or 7mm neoprene knee sleeve? That is the question." So that was my attempt at a lame joke, but all kidding aside, for those of us that do weightlifting, CrossFit, or just general training, it is a question that needs an answer. When it comes to neoprene compression and support knee sleeves, these are the two most popular sizes, but there is a distinction between the two.
With neoprene knee compression, you are getting mild compression, warmth for recovery and injury prevention. This is what makes this product great for those doing a lot of lifting with their legs, especially explosive movements that are common in any WOD.
The biggest factor in selecting the thickness that is right for you is the type of training you are doing. For those lifting heavy weights, 7mm is your best bet. While 5mm is aimed more at conditioning workouts. Another thing to consider is the warmth factor. 7mm knee sleeves definitely provide more warmth and compression. The compression helps speed up recovery and reduce stiff muscles and joints by retaining heat, which in turn reduces risk of injury.
It is because of this we created the So Alpha 7mm Neoprene Compression and Support Knee Sleeve (seen below). We made this knee support sleeve with the best neoprene available. This means that you get top-of-the-line support as well as ease of movement. These were designed for athletes by athletes and that means that these can be used daily and they won't stretch out or come apart at the seams. Dish out your hardest workout and they will be ready for more.
