Packing for a round-the-world trip is never easy; space is always at a premium. That's why we created the Blue Kazoo. It hits that sweet spot of welcome warmth, low weight and squash-down compressibility. It's stuffed with more than 400 g of 700-fill responsibly-sourced down that, with the help of the included compression sack and the space-efficient 'mummy' shape, packs down to a backpack-friendly size and keeps you warm to a limit of -9°C. Plus this down is ProDown™ – treated with a water-resistant finish, so it takes damp and humid conditions in its stride. A close-fitting hood with cinch cord means you can seal in valuable body heat. Zonal anti-compression pads help prevent the down from losing its lofty warmth during the night. Though if you get hot feet you can unzip the bag all the way to the bottom. And if you're a fidgety sleeper, you'll make good use of the pad loops to attach the bag to your sleeping mat. Finally, being made from durable ripstop fabrics, this is a bag you can rely on, trip after trip.
