Kammok | Thylacine: 3 Sleepings Bags in 1

The Sleeping Bag
For All Seasons

Variable Warmth Technology™

Through a unique change in interface (Variable Warmth Technology™), the warmth of the Thylacine can be adjusted through a system of insulated liners to adapt to a variety of distinct environments. By layering additional, removable liners and inserts inside the base sleeping bag, the Thylacine can increase its warmth in increments of 15 degrees.

The beauty of this design is the entire Thylacine system is the equivalent of owning three different temperature rated sleeping bags in one, at a fraction of the cost. Since the liners and inserts are sold separately, buy only what you need, when you need it, and customize the bag for your comfort since down and synthetic (2016) bags, Liners, and Liner Inserts are interchangeable.

The Thylacine Bag keeps you warm in moderately cold temperatures

Add the Thylacine Liner into the base bag to increase warmth by 15°

Combine the liner and liner insert to increase warmth by 30°, creating the warmest bag for the coldest temperatures


Customfit™ is a break-through in sleeping bag innovation, giving you control of the optimal width and length dimensions of the bag. Goodbye cold spots. Hello next-level comfort.

Advanced Materials

The Thylacine combines all the elements that define a great sleeping bag – silky, soft, lightweight fabrics, advanced insulation technologies, 3D construction, durable hardware, snag free zippers, and a beautifully functional design.

Vaulted Footbox

Cramped feet results in an uncomfortable night’s sleep. The 3D construction of the footbox gives your feet ample room, whether sleeping on your back or your side.

Storage Pocket

Concealed accessory storage keeps your phone / keys / headlamp in reach and out of sight.
