The Endura Hummvee Gilet Vest provides versatile core body protection for windy days. The Hummvee vest features windproof front panels with DWR finish that is PFC-Free, non-toxic durable and water repellent. The vented rear mesh back panel disperses heat build-up, and the vest packs down small for stuffing in your jersey pocket. Adjustable hem and lycra bound armholes refine the fit, while the soft microfiber collar panel provides comfort and warmth. Reflective trim provides low-light visibility.
