Every aspect of these straps are thought through very well. The fabrics are threaded in a way to prevent fraying. The in house designed buckles draw it all together in a way that no other strap manufacturer gets right. They are well designed and manufactured. So many others get this wrong. They use cheap cheap cheap buckles and it makes the strap an absolute boner kill. Stu used his noggin on this one and made some buckles that are designed for a HUMANS ARM.
