OTB Side Armor Bags Over The Beach Operations are some of the most challenging and miserable operations that service members must endure. We are proud to bring a suite of products that directly results in improved load carriage and soldier survival during sea borne operations. The OTB product line is built with a mesh material which allows for quick drainage of water and sea borne debris such a sand. OTB products will dry faster after exiting the water and will drain water faster and more efficiently as well. The mesh also makes the products simple to clean using fresh water after conducting operations in salt environments. The LV/ Side Armor Bags - Over The Beach (OTB) The Mfg: Spiritus Systems
