System Dual Protection

System Dual Protection (SDP) is Keela Tactical's proprietary double-membrane fabric technology, developed for and extensively used in specialist military applications.

Unlike conventional waterproof fabrics, SDP features two distinct layers working in tandem: a tough, durable outer membrane that withstands the rigours of field use, and a lightweight inner membrane that traps warmth and creates an air gap to manage internal condensation. The result is a system that is waterproof, breathable and insulating — without requiring an additional base layer to handle moisture.

By actively reducing inner condensation, SDP keeps the wearer drier from the inside out, maintaining comfort and core temperature during prolonged operations. It's the technology behind Keela Tactical's most trusted jackets, trousers and over-garments — and the reason our kit performs where others fall short.
