Sure, the lead sled dog gets all the glory. But running on his heels are two overlooked, but no less critical, team members: the swing dogs, who staunchly keep the sled on track on steep slopes and sharp turns. Similarly, our Swing Dog Crew helps you stay the course on the coldest days. With a mesh face and smooth interior, the 8-oz. 86% polyester/14% cotton knit warms your core while wicking away moisture. Stretch mesh inset between the shoulders dissipates heat and sweat. Raglan sleeves and bulk-free side panels instead of seams give you a smooth fit under layers. Put ’em on your team and run winter into the ground.
