Why Silksaks work


When travelling in warm climates a Silksak is the perfect lightweight alternative to a regular sleeping bag. You’ll feel cool and comfy as your Silksak keeps your skin dry and your temperature down PLUS gives you protection from biting insects.


When used inside a sleeping bag your Silksak adds extra warmth, working with you to keep your body temperature even. It also extends the life of your sleeping bag by keeping it clean inside PLUS the fine, smooth fabric reduces unpleasant tangles in the night!

Silksaks are very soft and extremely lightweight. Each Silksak can be stuffed into it’s attached stuff-bag for storage. A Silksak will take up minimal space in your luggage.


A single silk fibre has a tensile strength equal to steel wire of the same diameter. Our fabrics are very strong and durable. They will not go into holes or rip easily.

Fast drying

Silk keeps your skin dry because the hygroscopic silk fibre absorbs one third its own weight in moisture without feeling damp. The absorbed moisture is evaporated into the environment or absorbed by outer clothing layers. Your Silksak also dries fast.

Safe and natural

Silk is a completely natural fibre. Silk is one of the safest fibres you can wear next to your skin because it is naturally flame resistant. Where synthetics melt, silk burns to harmless ash.

An all-season liner

Winter and Summer, your Silksak provides thermal balance. Use your Silksak to add luxurious warmth in winter to your regular sleeping bag. In summer or in tropical climates, use it as a super-lightweight, breathable bag on its own. It will keep you cool and keep biting insects away. A Silksak is the perfect travel companion.

Only silk is silk

Many fabrics claim to feel “soft as silk”or “silk weight” but what could be better than the real thing? Synthetic fibres such as polyester and microfibres were first developed last century from a desire to imitate the precious silk fibre. But silk has unique properties that no manmade fibre can imitate.
