Seager Bison Workshirt in heavyweight duck canvas
The Seager Bison Workshirt is a lightly insulated shirt jacket built from heavyweight duck canvas, with a smooth lining and light poly insulation that add real warmth without extra bulk. A contrast corduroy collar brings a classic finish to the rugged canvas build, while welt hand pockets and dual chest pockets round out the workwear details. Cut oversized for easy layering, it throws on over a tee or layers up once temperatures drop.
What Our Gearhead® Experts Are Saying:
"I expected the insulation to make this feel stiff over a flannel, but it moves like a regular shirt jacket even layered up. The canvas blocks enough wind that I've worn it solo on cold mornings without reaching for anything heavier."
