The 3L Guide Jacket is the most technical jacket Gramicci have ever made. Built to withstand the elements, it’s made from a lightweight three-layer Flytec Defend fabric that’s waterproof, windproof and breathable. They’ve also added a watertight zip to make sure the wet stuff definitely doesn’t get in, along with a large drawstring hood and some perfectly angled chest pockets for all your important bits and pieces.
