Looking for 18mm Single Pass NATO Style Straps

Having a hard time finding straps that meet these needs:

-18MM
- 3 ring
- Single pass NATO style
- Olive/army green OR black w/ a cream/off-white middle stripe

I used to buy these 3 ring heavy NATOs from Clockwork Synergy (https://www.clockworksynergy.com/shop/product-category/nato-straps/heavy-nato/), but my last few orders get canceled and refunded, hope they aren't going out of business! So these are not an option.

If you're curious, this is to be paired with a Hamilton Khaki Pilot Pioneer.

Thanks!
