Quality price to help with posture and upper back pain. I recommend this to my patients to help with upper back pain and strains and have gotten good response.
Made from the same material used on big rip tow straps-- these babies aren't going any where. Rip up your wrists but it's worth it and shows your strength.
Despite the name, I use it on my reverse hyper mostly and it works very well. Shows signs of wear after regular use but still sturdy, not fraying, and great function.
Often times free, I have never actually bought them because they came with a barbell or weight set. I have never had one slip off, but often they come misaligned and are difficult to get onto a barbell or peg. They are fine as a starter.
