I purchased the product online having never seen one up close. It was a shot in the dark for me and figured there was a 50/50 chance of getting something worthwhile. I've used it several times now and as it turns out it was a shot in the dark that paid off. It breathes well - supports my back way better than I thought it would and fits nicely either over or under my clothing. Too soon to tell about durability but so far so good. It is well constructed and so I expect its durability to be high. I would definitely purchase this belt again.
