Guys in Duluth calmly go about their day in bone-chilling cold. Is it their Scandinavian ancestry keeping them warm? Maybe a bit – but they also rely on beefier shirt jacs. This one is our famous Burly Thermal fabric – a super-hearty, soft and lofty 62% polyester/38% cotton knit with a waffle texture that holds in heat. We’ve lined it with thick, fuzzy polyester sherpa bonded in place to prevent bunching. Warms like two layers, wears like one. Better yet, we’ve tweaked the fit – now in Standard Fit with a bit shorter length, because you said so!
