Perlon and RAF style is my favorite watch strap. Nato straps can be bulky, but RAF style straps are single layer and they're more comfortable to wear. This strap can be micro adjusted to wearer's wrist as it doesn't have designated holes. Also, PERLON dries faster than traditional nylon straps after getting wet, and doesn't cause your wrist to sweat.

The buckle and keepers on this strap are better quality than most comparable straps.
