The original Infrastructural Navy uniforms were heavy, comfortable, warm and well suited to the Icemountain Sea and other northerly waters. However as it's ships ventured southwards in it's regular escort duty these qualities would often be a sweaty burden, even with jackets set aside and sleaves either rolled up or cut off. As such in 34 IA were put into production for warmer waters. Made mainly from thinner imported cotton and died lighter colors these uniforms were very well received by enlisted sailor and naval officer alike.
