Atmos™ is our proprietary ripstop nylon fabric, made from high tenacity yarns with thermal reflective properties and blends of unprecedented durability. Atmos™ amplifies body heat retention, maintaining a comfortable equilibrium wherever adventure takes you.


Constructed with Insotect Flow™ technology, the Koala™ regulates an even distribution of warmth through the use of Vertical Thermal Channels (VTC’s) and Flowgates™. Heat rapidly spreads through the underquilt to keep your body at optimal toastyness.


No two people are the same size, nor do two people sleep the same way in their hammock. CustomFit™ adjustments provide the perfect contour to your body, eliminating cold spots and maximizing your comfort.

Care Instructions

Storage Instructions

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 and it's why we didn't store your gear in it's stuff sack. Make sure your gear is completely dry before storing it.

Cleaning Instructions:

Spot clean or hand wash 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 do not 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. Never dry clean.
