The Co-Pilot has been produced from a lightweight, garment dyed parachute silk and includes internal wadding for additional insulation. Inspired by early Osti designs, the garment features a magnetic snap front fastening with zip, two front lower pockets secured by magnetic snaps, adjustable cuffs and a ribbed hem. The garment dying process means the fabric picks up a wonderful array of highs and lows, giving it a sense of depth that few other processes can offer. The Co-Pilot also includes a British storm-fasten across collar as seen on classic Harrington jackets and features under arm venting complimented by a loose lip back yoke to promote greater air circulation and overall range of motion. Inside you’ll find Boneville signature herringbone taping for support at key stress points.
