The K9 Helm CS-1 Ear Covers feature a low profile design, soft rubber connector strap, and EVA foam padding that provides insulation from cold weather and will not absorb water. The streamlined covers add only 10mm of overall clearance to the helmet when installed — a huge benefit in the cramped spaces of an aircraft or vehicle.

​Many special operations K9 handlers use custom, molded ear plugs because it's the best solution to protect the dogs' hearing. However, plugs can become dislodged and lost. The CS-1 Ear Covers help prevent this. (By themselves, the covers complete the helmet shell's coverage, but do not offer decibel reduction.)

​Note: The CS-1 Ear Covers DO NOT fit any of K9 Helm's earlier Trident helmets.
