NemoSonic -20 - Sleeping bag

On icy peaks or mountain trails, having a reliable ally can make all the difference. The Sonic -20 sleeping bag from Nemo stands out as the ideal companion for facing extreme temperatures. Thanks to the revolutionary Thermo Gill™ technology, this bag adapts to temperatures ranging from -28°C to 4°C, offering tailored comfort. Imagine being able to adjust the warmth with a simple gesture, even in the middle of the night, thanks to its multi-level zipper system.

The chevron construction of the Sonic's down compartments ensures an even distribution of warmth, eliminating any risk of migration. Impressively, its shell and lining are made from 100% recycled fabrics, and the 800 FP hydrophobic down is RDS certified. These ecological choices do not compromise performance; on the contrary, they add a responsible touch to your adventures.

Finally, the Toester™ footbox, a true cocoon for your feet, ensures insulation and protection against moisture, while allowing you to dry your belongings. Whether the mountain holds surprises or not, the Sonic -20 is ready to resonate as your best ally in extreme conditions.
