The JF1625-TG 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 breath-ability and comfort. Tested to maintain protection for light welding applications through 50 home washings.
