The Zestos model is a core product in the Up In Smoke Welding Apparel product line and is designed to be worn in warmer climates. Our Zestos shirt is flame-resistant and the most lightweight product in our entire line, providing you with more relaxed comfort in warmer environments.

8 Things to Know About the Zestos:

  • We use lightweight North American Mount Vernon Mills FR twill.
  • The Zestos is the lightest weight garment in our product line.
  • For extra protection, the Zestos has a tall collar.
  • The design includes two front pockets that can fit an iPhone 10 (without a case).
  • The design also includes a pen slot in the left pocket.
  • There are 7 American-made YKK snap front closure.
  • We’ve extended the rear tail of the shirt for added protection.
  • We use heavy-duty Canadian-made FR Nomex and Kevlar thread to tolerate the abuse our products endure.
Please note that while Up In Smoke’s welding apparel performs better than anything on the market and is well suited to welding environments, our garments are not indestructible. Our garments will protect you and are more durable than the other options on the market, but our garments will still wear down after extended use in harsh conditions.
