Nordisk Iver + 0° Mummy Sleeping Bag - Size XL | Buckthorn Brown/Harvest Gold

Let nothing keep you from reaching for your dreams - performance cut down sleeping bag for three seasons.

Imagine waking up to the crisp mountain air, the world around you still blanketed in the quiet of dawn. Your body feels cozy and warm, nestled inside your Iver ±0. As you stretch, your torso feels completely at ease—no tightness, no restriction—just an incredible sense of freedom as you move naturally, thanks to the intelligent, extra-wide torso section. It’s almost hard to believe you’re in a mummy sleeping bag at all.

With Iver ±0, you get the space and comfort you crave without sacrificing warmth. The innovative cut of this bag provides an open, airy feel in the upper body, letting you move freely without feeling confined. Whether you’re shifting around to adjust or just reaching for your gear, the extra room in the torso section ensures you won’t feel trapped, as you often would in a traditional mummy bag. It’s the perfect balance of warmth and freedom of movement.

At the same time, the lower part of Iver ±0 is strategically designed to be heat-efficient. The knee and foot areas have a more snug fit, helping trap and warm the air in those areas quickly. This keeps your legs and feet toasty warm, without the need to work hard to heat up unnecessary space. The sharkfin footbox ensures there’s just the right amount of space to keep your feet comfortable and protected from the cold.

As you wake up, ready to tackle the next leg of your journey, the adjustable 3D hood moves with you like a jacket hood, making it perfect for those moments when you’re not yet ready to leave the comfort of your sleeping bag. You can adjust the thermal collar to lock in the warmth and keep out the cold, ensuring that every bit of heat is preserved throughout the night.

Made with a durable yet breathable ripstop shell, Iver ±0 holds up to the demands of your toughest adventures, while also being light enough to keep your pack size small. And with RDS-certified European duck down filling, you can rely on the warmth and performance of a high-loft down that will keep you comfortable down to -3°C, with a built-in safety reserve for those unexpectedly chilly nights.

Perfect for trail runners, bikepackers, hikers, and climbers, Iver ±0 is your ultimate companion for staying warm and comfortable without the restriction of a traditional mummy bag. It’s a sleeping bag designed to enhance your outdoor experience—giving you the space to move, the warmth to rest, and the peace of mind that you’re making an eco-conscious choice with 100% recycled fabrics and PFAS-free materials.

Whether you're setting off on a long trek, a mountain climb, or a bikepacking adventure, Iver ±0 is there to keep you cozy, letting you enjoy the freedom of movement while keeping the cold at bay. It's a sleeping bag that doesn’t just keep you warm—it keeps you comfortable, unrestricted, and ready to embrace whatever the outdoors has in store.
