Washed indigo denim quilted over recycled insulation, with a cropped cut and a sherpa-lined collar.
Cut roomy to fit a mid layer underneath. Take your usual size for layering, or one down for a closer fit.
Free tracked shipping on qualifying orders, delivered in two to four working days. Return any unit within 30 days, unworn and with its tags.
// Layering protocol
Base. Mid. Shell.
Start with a merino base, add an insulated mid layer and finish with a shell over the top. Three layers trap more warmth than one heavy coat, and you can shed them as you move.

Packs tiny
August 11, 2026Squashes into its own pocket and comes out with no creases. My go-to for travel now.

Warm but loud
July 5, 2026Very warm and well made, but the fabric rustles more than I would like on a quiet commute.
