Unlike other sleeping bags that leave you feeling trapped and constricted, Iver +5 offers an unusual sensation of space and freedom. As you sit up in the early morning light, ready to stretch, you realize just how effortlessly the bag moves with you. Its intelligent cut, with an extra-wide torso section, gives you the room to move and adjust without feeling confined. It’s hard to believe this is a mummy sleeping bag—the space it provides is something you’d expect from a larger bag, but the design ensures warmth where you need it most, without excess bulk.
As your feet slide down into the sharkfin footbox, the snug fit helps trap heat, keeping your feet warm and comfortable throughout the night. No more cold drafts or wasted warmth. The tighter fit around the lower legs and feet is designed to warm up quickly, while the top remains spacious enough to allow for natural movement. It’s a perfect balance of comfort and functionality.
Whether you're in the middle of a trail run, bikepacking adventure, or high-altitude climb, Iver +5 ensures that you have the freedom to move without sacrificing warmth or performance. The 3D adjustable hood sits comfortably, like a jacket hood, moving with your head as you sit up in the morning or shift positions. It’s the small, thoughtful details that make Iver +5 feel like an extension of your body, offering the warmth and comfort you need, exactly where you need it.
The tough, ripstop shell stands up to the challenges of the outdoors while being lightweight and breathable. The RDS-certified European duck down filling, packed in Germany, offers reliable warmth for temperatures down to 4°C. With 100% recycled fabrics and a design with no intentionally added PFAS, Iver +5 doesn’t compromise on performance.
With Iver +5, you can rest easy, knowing your sleeping bag is as adaptable, durable, and comfortable as your own body—designed to perform, move, and keep you warm on your next adventure.
