The Boost 650 sleeping bag delivers versatile comfort for backpacking or car camping. Its roomy semi-rectangular shape lets you sleep freely, while the WarmZip system converts it into a heat-efficient mummy bag—adding up to 10°F/6°C of extra warmth when needed.
Arm holes and a two-way zipper provide easy ventilation and convenience, and durable YKK anti-snag zippers ensure smooth use. Lightweight and packable, the Boost 650 features zoned 650-fill hydrophobic down, a soft 100% recycled nylon shell, and PFAS-free water resistance to keep you warm and comfortable in changing conditions.
