Description
When the temperatures drop well below freezing, and the winds howl in the deep winter, Knuth-20 is the sleeping bag you can rely on to keep you warm and comfortable. Designed for those who venture into the harshest conditions, this high-performance sleeping bag is built to handle extreme temperatures as low as -20°C, making it ideal for winter camping, hiking, and bushcrafting.
Knuth-20 is packed with features that make it a true winter companion. The adjustable 3D hood wraps around your head for added warmth, while the spacious sharkfin footbox gives you room to stretch out without sacrificing heat. The two-way side zip allows for easy access and ventilation, so you can adjust your comfort level as needed. The adjustable thermal collar prevents cold air from sneaking in while trapping your body heat, ensuring you stay warm through the night.
For even more versatility, Knuth-20 includes a secondary shoulder zip, allowing you to free your arms while still keeping your core and head insulated. Need extra ventilation or cooling? The zippered footbox opening lets you regulate temperature without letting the cold in.
Made with a tough nylon ripstop shell, a soft-touch lining, and ultrasoft filling, Knuth-20 combines durability with comfort. It’s also crafted from 100% recycled fabrics and filling, and contains no intentionally added PFAS (C0), without compromising on performance.
Whether you're trekking through snowy landscapes, building a shelter in the wilderness, or embarking on a remote winter camping trip, Knuth-20 ensures you stay cozy, protected, and prepared for whatever the deep winter throws your way. Experience warmth and security even in the coldest conditions, and sleep soundly knowing you have a sleeping bag built for the extreme.
