Frequently Asked Questions

Do I need a liner?

Depending on the weather conditions you are camping in, you may 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, the Thylacine 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 Liner?

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 liner in tip-top shape by spot cleaning or hand washing when possible. Hand washing your gear with cold water and Grangers Down Wash + Repel is best for extending its useful life, but it can also be cleaned in a front-load washing machine (do not use a washing machine with an agitator).
Washing machine instructions:

  • Zip up the liner.
  • If the gear is soiled or stained, use the recommended amount of Grangers Down Wash + Repel. Do not use fabric softener, bleach, or stain removal products.
  • Wash the gear by itself using the gentle/cold water setting.
  • Hang to dry, or use the delicate, no heat tumble setting on the dryer with a clean tennis ball, or dryer ball. Do not stuff back in stuff sack damp or wet.

How do I store my Thylacine Liner?

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 or hang in a dry location. This keeps your gear fluffy when stored for extended periods of time.
