The Syntek 0° Dark Orion/Wild Lime is a trekking sleeping bag from the Millet brand, designed to provide you with maximum comfort so that your nights in the mountains are as pleasant as possible. Filled with synthetic insulation which retains body heat up to temperatures around 0°C, this bag has a stretch internal lining and a matte external material for a more pleasant touch and more comfortable sensations. Practical, it incorporates the Bivy Warm™ system allowing you to take your arms out of the bag without completely revealing yourself. To protect you properly, it includes a tightening hood accompanied by shoulder collars. In addition, its sarcophagus shape close to the body improves thermal protection and the anti-cold flap provides better insulation. Finally, the compressibility of the insulation allows the bag to be compacted into a small, lightweight package, ideal for summer adventures.
