New natos you can buy directly through Omega website, last time when I checked is was $160/piece, so don't see a reason why to pay $400 for a pair.
There are more expensive nato models (Biosteel) but straps on your photo are $160 afaik.
I have two Omega natos - very good quality but I think no nato strap is worth $160 no matter who has produced them. This is kind o fthe item you buy to spoil yourself.
