Assuming you go for a PROPER NATO spec and not the, IMHO, awful cheap and chubby looking Zulu type that makes everything look like a $5 replica or Animal watch, try and get something that will coordinate with the red/blue. AND my preference would be to order the so-called RAF Pattern variant, or if unavailabubble, simply cut and heat seal (easy peasy) the extra and IMHO POINTLESS extra strapping on the NATO - and have the avantage of losing the extra s/s loops.
Well, you asked.....
