NATO vs Zulu vs Single-Pass Straps: What’s the Difference?

Many people call every nylon strap a “NATO,” but there are real differences that affect comfort and how your watch sits on your wrist.

NATO (traditional, double layer)

Traditional NATO straps add an extra layer under the watch head. It can increase security but also adds thickness.

Zulu (usually thicker, rounded hardware)

“Zulu” straps often use chunkier rounded hardware and thicker nylon. They can feel tougher but may wear bulkier.

Single-pass (best for comfort)

Single-pass straps reduce bulk because there’s only one layer under the watch. If your watch feels too tall on a NATO, single-pass is the fix.

My pick

For most field watches, single-pass is the sweet spot: comfort + security without extra height.
