The first 50 miles test your legs. The second 50 test everything else. The 100 Miles Mountain Outline Crewneck Sweatshirt is for the ultra runner who has chased the hundred, finished it, or is training to, and wants to carry that quietly.

A clean line-art mountain range sits over a small "100 Miles" mark on the chest, with a subtle detail on the sleeve. No loud graphics. The people who know, know. Pull it on at the finish line, on the drive home, and through the recovery days that follow. The Duck earned the miles. The Sloth earned the sweatshirt.

Is it made for running? It is made for everything around the run: race morning, the finish area, travel, and recovery. It is a warm cotton-blend fleece, not a technical running layer.
