The Black Stallion JF1625-NG Stretch-Back FR Cotton Welding Jacket offers all the protection of our standard welding jacket, with the added comfort of a lightweight and breathable flame-resistant cotton stretch knit back panel. The looped knit yarns of the back panel offer just the right amount of horizontal "give" as a welder moves his shoulders and arms. And, these looped yarns allow more air to flow through the fabric, providing cooling breathability, and comfort. Tested to maintain protection for light welding applications through 50 home washings.
