Livewire 1/4 Zip DH Shirt


Our Power Grid fire resistant (FR) dual hazard 1/4 zip shirt provides maximum warmth to help you cope with the most extreme cold.



1/4 Zip Shirt is constructed with Power Grid 4-way stretch fabric that offers enhanced comfort and range of motion. The unique grid construction maximizes warmth, minimizes weight, and improves breathability. We decreased the fabric weight by over 20% while increasing the Arc Rating from CAT 1 to CAT 2, plus we improved the stretch to improve comfort and range of motion.
