This suit is pre-treated with a Class A fire-retardant Our same High Quality Jute Thread is sewn directly on to a Military BDU 4 pocket coat. These are made by Propper. The sewn on Jute thread covers the entire Back of the jacket tops of the arms and shoulders. The Hood is attached and thumb loops are sewn into the cuff of the sleeves for crawling. The Front Chest area and the forearms have a 1000 Denier Cordura Plus material sewn on for those long Sniper crawls. The Cordura Plus means it has a Urethane Coating for water repellency. The Hood is built the same way we build our Ghillie Poncho - by hand tying the Jute thread to a 1x1 netting finally sewing this to the Jacket. This design keeps you cooler allowing the wind to pass through and allows for better hearing. All the buttons on the chest have been removed and Velcro has been sewn on to secure the jacket closed. This makes your crawl more comfortable without feeling the buttons ( Weight 6 lbs). If Propper brand is unavailable at the time we will use Tru-Spec Brand.
