Expect it to earn a permanent place on your coat peg. The Fire Hose® Limber Jac is just as tough as you'd expect a Fire Hose shirt jac to be – made of rugged 100% cotton canvas. But at 8 oz., it's a lighter-weight canvas that's great in milder weather or when you're on the move. Lined with comfortable, chill-chasing flannel that won't overheat you or weigh you down. Reach Gussets™ guarantee you're never held back when you reach, swing or go through any contortions needed to get the job done. Even has side hand-warmer pockets – a feature you demanded! Bundle and save . 🚨please note I’m a teacher and I only go to the post once a week on Saturdays
