The International Harvester trucker cap is great for summer wear. To keep you feeling cool and comfortable in those hot temperatures, this hat features a mesh back for breathability. The front is made from 50% cotton/ 50% polyester and features the International Harvester logo. The Velcro adjustable back closure is easy to use and helps provide the best fit possible. As with all Farmall/IH hats, this Trucker Cap is one size fits all.
