The Chamois Insulation Vest is a lightweight insulation layer built to trap warmth through the core without the weight or bulk of a heavier vest. The fit runs close to the body to maximise insulation efficiency — which means slightly less room for layering than a standard fleece gilet or windproof vest.

• Fit: Close to slightly roomy through the chest and body depending on what's worn underneath — designed to maximise heat retention without unnecessary bulk
• Layering: Designed to sit over a base layer or light mid layer — a heavier fleece underneath will make the fit feel tight and reduce insulation efficiency
• Arms: Sleeveless design keeps your arms free and makes reaching and moving easier without the restriction of a sleeved jacket
• Body: Lightweight insulation keeps you warm through the core without the bulk of a heavier insulated vest — the close fit is doing the work
• Hem: Adjustable drawcords let you cinch the vest in for a closer fit and lock the warmth in at the bottom
• Overall feel: Light enough to forget about, warm enough to notice when you don't have it — the kind of layer that earns its place without getting in the way
• Sizing: Your usual size works well over a base layer. If wearing directly over a base layer and wanting a closer, more insulating fit, consider sizing down. If layering a mid layer underneath, size up.
