I have other NATO strap (not from GadgetWraps) that is much much thinner than this one. The GadgetWraps strap is thick (looks like double layer) and looks much better than what you see in the picture. Lengthwise is better than the original strap from my Pebble Round. I have tiny wrists and in the original strap I was using the second hole. In this NATO strap I use the fourth! It is very comfortable and soft in the wrist too.
I'll probably buy more of this straps for my other 3 pebbles :)
