Best back brace I have ever owned. It's even comfortable to sit with, which is rare. The additional pull-straps on either side of the belt allow you to adjust the tightness even further, so you have many grip options depending on what you are doing when wearing the belt. If you need a looser grip when walking versus weight lifting, adjusting those additional straps may do the trick alone. If not, removing and readjusting the belt is easy.
The velcro does not move or stretch. The belt holds secure.
This brace is not too rigid, so it does not bite into your skin. Even when you are performing exercises or everyday activities that require bending or stooping. I love that about this belt. It blends superior function with reasonable comfort.
Furthermore, if you are injured and need to wear it all day, the belt can easily be concealed under a shirt or sweater. It feels fine against bare skin, but I would not recommend going literal "bare back." Over a light t-shirt would keep it from chafing or soaking up sweat.
Definitely gets you back into the action when you are hurt or sore. Definitely keeps you from accidentally hurting yourself when doing more strenuous things. Definitely a good weight-lifting belt. And--as a plus--it looks much cooler than those hard leather horse saddles some people wear in the gym. Not for power-lifting, though.
If you have even a twinge of discomfort in your lower back, I recommend you give this belt a try. It has an amazing hold, is manufactured from high-quality materials, and is the most comfortable brace I have ever worn personally. Just be sure to order the correct size!
