Kammok Thylacine Sleeping Bag

It allows you to adjust the internal volume and insulation distribution of the bag. By cinching or loosening specific areas, you can trap more heat on colder nights or vent excess warmth when temperatures rise, making it more adaptable than a standard mummy bag.

The sleeve is designed to accommodate most standard rectangular and tapered sleeping pads. It keeps your pad securely underneath you, preventing you from sliding off during the night, though extremely wide or thick pads may be a tight fit.

Downtek is a water-repellent treatment applied to the down clusters. While it isn't waterproof, it helps the down retain its loft and thermal efficiency much longer than untreated down if it gets damp from condensation or humid air.

The 20°F rating is generally considered a 'limit' rating, meaning it is designed to keep you alive and relatively comfortable down to that temperature. If you are a cold sleeper, we recommend pairing it with a high-R-value sleeping pad and wearing base layers to ensure comfort near the lower limit.

The regular size weighs 34 ounces, while the long version weighs 36 ounces. This makes it a competitive option for three-season backpacking where weight management is a priority.

No, the Thylacine is designed with a specific zipper configuration and pad sleeve system that does not support coupling two bags together. It is built as a standalone, personalized sleep system.
