I came across the above strap the other day and thought; why not?
George's Straps combines to comfort and elasticity of the MN strap in a traditional NATO strap design and is available in 10 different colours and two sizes; 20 and 22mm.
The quality is on par with other regular NATO straps, the hardware is functional, stitching neat and straight, and the holes appear well sealed against fraying. I particularly like that keeper near the buckle is floating.
Best part of all is that it's not going to break the bank at 12.99 GBP.
