Arc 3L Shell Jacket uses a stretch nylon three-layer fabric rated to 20K/20K for waterproof protection and breathability. The windproof shell is fully seam-taped, keeping the construction focused on exposed conditions.
A high collar meets an adjustable hood with a bonded brim. The two-way YKK waterproof front zip is joined by a chest pocket and two hand pockets, all positioned to keep storage protected, while rear elbow darts preserve movement.
Adjustable cuffs and side hem let the shell close down over layers, making the sharp silhouette work from wet trails to daily movement through unsettled weather.
