... that system got changed quickly with the OC III and now the Barakuda.
Once you have changed the MilSpec to (curved) spring bars, the change is done in a few seconds.
The sailcloth tang buckle has 16mm, the Tropic has a 18mm buckle and the Nato has a 20mm buckle. That’s a bit unfortunate, but each width works fine with the corresponding strap.
When it comes to strap dimensions, comfort and the aesthetics, the Tropic is probably the most compelling choice.
