These are made of 4-5 oz. buckskin leather rough side out. That enables them to slip on easier. They have two interior pockets accessible from the outside. I made these of a pattern from my favorite leggings that I've had for years. They're light-weight and easy to do ground work in. Everything is entirely double-stitched and should last for years. I'm 6 foot, 180 lbs. and they fit me perfectly.
