I have two ruptured discs (L4-L5) and play recreational tennis. I already have things like a tens unit, inversion table, etc which help in short spurts but this brace allowed me to play a 3 hour high intensity singles match. It protected me from any further injury and allows me to continue playing the sport I love. Great value. I have not yet attempted to launder it, but it seems very well made and is extremely comfortable. I’m 6’ 2” and just under 300 lbs and the XXL fits me perfectly. I highly recommend for anyone working to prevent lower back injury and continue to stay active.
