A popular low-profile 1.5" Low Pro TDU Belt manufactured by the renowned 5.11 Tactical company. It will work well in everyday use as a lightweight and inconspicuous pants belt.
It is made of a strong, nylon tape, 3.8 cm wide. The buckle is solid plastic, with special, flattened construction. Thanks to this, it does not stick out significantly, grabs attention, or hooks into other parts of your equipment - e.g. tactical vest.
