Regular Nylon vs. Seat Belt Nylon

The regular nylon is stiffer and more rugged — it takes some breaking in but will mold to your wrist with wear and become very comfortable. The regular nylon is the way to go if you want the most rugged material possible.

The seat belt nylon is softer and more flexible right out of the box, so it's better if you don't want to wait for break-in.
