I confess. There are times at home when I’ve broken open my silk sleep sack because I crave sleeping in my personal cocoon of luxurious, natural silk. I bought it for camping, hostelling and times when the cleanliness of off-the-beaten path accommodation might be suspect. But, when the comfort of silk beckons, my silk sleep sack answers the call. If you can relate, pack a silk sleep sack when you travel.

What’s a silk sleep sack?

It’s a sleeping bag liner made of silk. Silk liners are the lightest and most compact of all sleeping bag liners.

Silk is recognized for its odour-resistant and moisture-wicking properties. When travelling in warm climates, a silk sleep sack is the perfect lightweight alternative to a regular sleeping bag or bedding. You’ll feel cool and comfortable as your silk sleep sack keeps your skin dry and your temperature down. It offers warmth when a fan or air-conditioning unit is working overtime. Plus, it offers protection from biting insects.

When used inside a sleeping bag, a silk sleep sack adds warmth, working with you to keep your body temperature even. It provides an insulating layer that traps warm air next to the body. A liner between your body and the sleeping bag extends the life of your sleeping bag.

In a nutshell, silk keeps you warm if you’re cold and cool if you’re hot.

My choice

After much research, I settled on the family-owned New Zealand company Silkbody, producers of the Silksak. I was also attracted to the company’s commitment to sustainability, fair wages for the employees of its Asian-based suppliers, and its use of recycled packaging.


I purchased the “Pillow (YHA) Silksak” in 2013. What attracted me to the YHA version is the built-in pillow envelope. A glorious layer of silk separates my head from the pillow nestled inside the pocket.

Entry to the sleep sack is via a side-split opening with a gusset.

A storage bag is attached. It will never go missing. I appreciate this feature.

My Silksak takes up next to no room in my pack. It’s lightweight and compact, easily washed in the shower or a sink and dries very quickly.


  • Size: 86 cm (34 in) wide x 220 cm (87 in) long (including pillow slot);
  • Weight: approximately 136 g (4.8 oz), including stuff bag;
  • 100% silk;
  • It comes in a multitude of colours.

Earth-friendly product

Sericulture (silk production) is earth-friendly. Silk caterpillars eat mulberry leaves from trees that produce year after year. The trees are replaced after 8 years, after which they’re not such vigorous growers and the leaves aren’t so tasty to caterpillars.

Pesticides can’t be used on mulberry trees as silk caterpillars demand the purest and best quality leaves as their food.

Silk is biodegradable and will decompose easily in landfills.


The Pillow (YHA) Silksak is available from Silksak’s store, SilkLiving. It currently costs $77 NZD ($56 USD) plus shipping costs of $11 USD (worldwide). First-time orders attract a 5% discount.

It’s also available from other suppliers in New Zealand.
