The Battle B from the American company Kore is the first ever combat belt that is adjustable in very small (micro) increments. Thanks to this, you can precisely adjust the tightening or loosening of the belt to your current needs.
This belt has a hidden rail with more than 20 adjustment points and micro increments of about ¼" (about 0.64 cm). Thanks to this, you can always adjust the tension of the belt perfectly. After a hearty lunch, you loosen the belt and vice versa when you need to carry rich equipment, you will tighten it again.
In fact, in the case of Kore Battle B, it is not just one belt, but a system of two belts – inner and outer. This solution offers the wearer the possibility of optimal distribution of the load. The belt is strong enough to carry full size weapons, magazines and other tactical equipment up to a weight exceeding approx. 9 kg.
