The 20mm DUO pack contains two flexible nato straps total. One is a tan with a red central line, and one is a green with a white central line.
The Flexible NATO straps are perfect beater straps that happen to look and wear very nicely. They are worn like traditional NATO straps, with the added benefit that they provide a little bit of stretch and flex. This is great for those of us whose wrists tend to swell a little as the day progresses and increases comfort for just about anyone. Fun little straps to add to the mix without breaking the bank.
