Fitment was exactly as stated. I measured my hand width and cross-referenced that to their graph and picked my size (XL). When they arrived, I immediately tried them on and they are a perfect fit even though I have thick hands. They are soft enough to not require a break-in period, too.
The palm material is soft and has some extra padding in key areas but feels durable enough to protect well for my needs. The stitching wasn't frayed and didn't look hurried. The backside material is flexible enough to allow a comfortable fist, and the rubber hand protection is in the right places to be effective without being rigid and restrictive.
These are great medium duty work gloves. Time will test their longevity, but at this price, I would happily replace them if they last even a year. I may get another pair for around the house, too.
