Description

Spacious, semi-rectangular bag when you want it, toasty mummy bag when you need it—the lightweight and packable Boost 650 empowers you to truly be comfortable in the backcountry.

• WarmZip™ Tech: Patent-pending center zipper design reduces the bag’s internal space and tucks insulation around the sleeper to boost warmth by up to 10°F/6°C.
• Power to the Sleeper: Enjoy the spacious freedom of the semi-rectangular bag or the cozy warmth of a mummy bag—pick the shape and temperature that keeps you comfy at night with just a zip.
• Multi-Use Arm Holes: Reach the WarmZip, read a book, play cards or simply ventilate—do it all while tucked into your sleeping bag.
• Puffed Up & Zoned Out: Ample 650-fill RDS-certified hydrophobic down is allocated to key areas with Zoned Insulation to maximize heat retention and minimize overall weight.
