Each Cocoon MummyLiner or TravelSheet has been tested and shown to add warmth to your sleeping bag as shown in the chart above using industry standard cold chamber testing.


100% Silk
Our breathable high-quality silk is the optimum fabric for minimizing packing size and weight. Toasty in the winter and cool in the summer, silk is breathable and soft to your skin. It is easy to hand or machine wash and dries quickly.
55% / 45% Silk-Egyptian Cotton
Silk-cotton combines Egyptian cotton and silk, our two most luxurious fabrics. The result is an exquisite and durable 55% silk / 45% Egyptian cotton blend that is slightly heavier and stronger than pure silk. Just width="50" like silk it responds well to changing temperatures, is compact and soft to your skin.
100% Egyptian Cotton
Egyptian cotton is a rare, long-fibered cotton that is spun into a fine yarn. The result is a very lightweight, fast-drying soft, yet durable fabric. COCOONŽ(s) made of Egyptian cotton are substantially lighter and more compact than the regular cotton ones. A great compromise between regular cotton and silk!
100% Cotton
Our high-quality cotton is breathable, creates a natural vapor balance and is very comfortable against your skin. Cotton is durable, machine washable and colorfast.
100% Flannel
Flannel is an especially soft and warm brushed cotton which affords more insulation than regular cotton. Flannel is perfect for cold climates or can be used alone as a summer sleeping bag.
100% Polyester Micro-fleece
Micro-fleece is lightweight and compact, warm, wicks moisture away from your body, dries quickly and is therefore practical in humid conditions.
100% Polyester Fleece
Fleece is warm and ideal under humid conditions because it absorbs little water, maintains its insulation value well and dries quickly.
