I purchased the slim fit as my first full belt, as a transition away from a ball-trap style cage. I was completely blown away by the attention to detail on the belt.
I have rarely seen a product so well described and spot on. After a few minor adjustments to the device, using the provided tool, I have been locked in for about 2 weeks now. No sores, no pinching, and no escaping.
I wish I had made the jump sooner.
