Linear Atmos Shell Jacket
Description
The Intent
A study in weightless verticality. The 412 Linear Atmos Shell is engineered for the gent whose life is characterized by high-velocity transit and a life sustained by routine. Utilizing a proprietary technical weave that provides a weightless thermal barrier and absolute wind resistance, the garment acts as a clinical modulator of the wearer’s immediate climate. The integrated high-neck architecture and adjustable toggle system ensure a statuesque silhouette that remains unyielding from the studio to the tarmac.

Care
Every CB garment is built to last. The weight and finish require a considered approach to care. Cold wash, inside out, on a gentle cycle. No tumble dry. Hang or lay flat to preserve the structural integrity of the fabric. Avoid direct heat on any technical shell or fleece component.
Correct care extends the life of the piece indefinitely. These are not disposable garments.
