Product Details Year: 2010 Country of Origin: USA Brand: VALLEY APPAREL L.L.C Material: Aramid Color: Tan Features: This is a CWU-45/P jacket issued to the US AIR FORCE in 2010. The biggest feature is the use of aramid, a flame-resistant fiber, for the body. The ribbing material also uses aramid fiber, which is a welcome point as it won't be eaten by insects like the wool ribbing used in the past. Furthermore, this is the TAN color for desert regions. Compared to the general sage green, there are overwhelmingly fewer of these, and this color is a rare presence even among flight jackets.
