It fit perfectly and was durable but couldn't resist the inevitable. One thing I didn't think of was that it kind of moved and covered her eyes. By scratching the tree, she succeeded. She quickly lost her temper and couldn't take the 1100-pound tantrum. It literally ripped apart. That being said, I think it would have been just as durable as a shoulder strap from the same company in other circumstances. The belt is adjustable. My girlfriend works 24/7. I put it on her around 8am and it was ready by lunchtime. It's also not a very heavy fabric, so even here in West Central Florida it's been 85-90 for the past few weeks and it almost seems to be absorbing moisture. I expected to see her soaking wet, but not quite. I would be very different if she wasn't constantly kicked out. Protects them from insects and the sun. Well done.
