Set apart from other sleeping bags, the Thylacine is tailored directly to your body with adjustments to control the width of your sleeping bag, minimizing cold spots and maximizing comfort. When equipped with a liner, the Thylacine base bag adapts to a range of temperatures and outdoor conditions without sacrificing premium performance or snuggly soft feel.

This sleeping bag is built to last and is covered under our lifetime warranty.

The crux of the Thylacine’s radically different interface is found with our patent-pending Variable Warmth Technology, delivering complete customization through a zip-in down insulated liner. Go from 20 degrees to zero degrees in 60 seconds.
The Thylacine Bag keeps you warm in cold temperatures at or above 20ºF.
Zip the Thylacine Liner into the base bag to create the warmest bag for the coldest temperatures.
No two people sleep the same way, especially in a sleeping bag. CustomFit™ adjustments provide the perfect contour to your body, offering one of the only fitted sleeping bag experiences in the industry. Simply cinch the straps to keep the bag snug, eliminate cold spots and maximize warmth in the backcountry.
The Thylacine is one of the most technically advanced sleep systems on the market. It is beautiful and functional design, cleverly combining silky-soft lightweight fabric, advanced insulation technologies, 3D construction, durable hardware, and snag-free zippers.
The Thylacine features the technology of Pertex Quantum GL fabric, incredibly lightweight, strong, windproof, and silky-soft to the touch.
Constructed with Insotect Flow™ technology, the Thylacine™ regulates an even distribution of warmth through the use of Vertical Thermal Channels (VTC’s) and Flowgates™. Heat rapidly spreads through the bag to keep you at optimal toastiness.
Water. Rain. Sweat. Snow. They are no match for the Thylacine’s 750 fill power DownTek™. DownTek™ shields those insulating-air-trapping-clusters from all wet things. DownTek™ adheres to Responsible Down Standard (RDS), upholding our commitment to the highest standards of sourcing.
No more pillow ‘slip and slide,’ the Thylacine pocket keeps your pillow in place while you sleep.
Concealed accessory storage keeps your phone, keys, or headlamp in reach and out of sight.
Cramped feet result 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.

The performance of this fill (heat retention!) is directly tied to its “loftiness." To help your products retain their loft, please follow our storage and cleaning instructions. Remember: Loft = warmth. Lofty gear = happy you.
Storage instructions: Where your bag sleeps when you’re not sleeping in it affects its lifespan. Before storing after a camping trip, avoid gnarly smells and damaged fill by making sure your gear is completely dry. Then, store lightly stuffed in a large, breathable bag (included) or hang in a dry location. This keeps your gear fluffy when stored for extended periods of time.
Cleaning instructions: Keep your down sleeping bag in tip-top shape by spot cleaning or hand washing when possible. If machine washing, use a front-load washer only and set to a warm, gentle cycle. Wash down product by itself with a cleaner specifically designed for down (NikWax® Down Wash). Do not use liquid detergent, and stay away from bleach. Rinse thoroughly, but do not wring. Air dry flat. Shake to restore loft or throw in a dryer on a "no heat" setting with a clean tennis ball. This product does not look good with a perm. Never dry clean.
