Insotect Flow™

Insotect regulates an even distribution of warmth to keep you at optimal toastiness, throughout the entire bag. In other words, no more waking up to cold spots.

EN Temperature Ratings

The EN 13537 test standardizes temperature ratings on sleeping bags.* When using the same insulation in the same environment, women generally sleep colder than men. The best guideline for women is the Comfort rating, while the best guideline for men is the Lower Limit rating.

Comfort: The temperature at which a standard female can expect to sleep comfortably in a relaxed position.

Lower Limit: The temperature at which a standard male can sleep for eight hours in a curled position without waking.

Extreme: The minimum temperature at which a standard female can remain for six hours without risk of death from hypothermia (though frostbite is still possible).

*These ratings assume the camper is using a sleeping pad, a tent, and is wearing one base layer of long underwear.

Frequently Asked Questions

Do I need a liner?

Depending on the weather conditions you are camping in, you do not need a liner to use the Thylacine Bag. Our down liner increases your temperature rating by 20ºF, bringing you from a 40ºF bag to a 20ºF bag when using synthetic, or upping the game from a 20ºF bag to a 0ºF bag in a matter of minutes.

How does the bag adjust to all conditions?

With a removable down liner that can add or takeaway warmth in seconds, this bag is the perfect option when you aren't sure what the weather conditions will be when camping. From 0ºF to 40ºF, the Thylacine has you covered.

How do I wash my Thylacine?

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.

Keep your 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.

How do I store my Thylacine?

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 with Down Base Bag) or hang in a dry location. This keeps your gear fluffy when stored for extended periods of time.
