Basically, liners are used in two applications – one, inside a sleeping bag and two, as travel sheets.

Protect your sleeping bagUsing a liner will keep your bag cleaner, which will mean washing it less often. It’s easy to come home from a backpacking trip and throw the liner into the washing machine (much easier than washing a sleeping bag). Your sleeping bag doesn’t have to smell like a student dorm room, and the oils from your skin don’t have to migrate into the insulation.  When it comes to camping, it’s not all about the sleeping bag; the smaller details matter too. It’s a good idea to care for your valuable sleeping bag, and for yourself, with a practical and versatile sleeping bag liner!

– To use in warm climates instead of a sleeping bag or sheets

– To help protect against biting insects

– To use in overseas hotels or hostels, protecting against potentially contaminated sheets

– To increase next-to-skin comfort, aid relaxation, and a good night’s sleep

  • Type – the two main type of sleeping bag liners are mummy bag liners and rectangular liners. Mummy bag liners are great for fitting inside a sleeping bag and keeping you snug, whereas rectangular shaped liners are generally better for beds and for moving about.


  • Material – sleeping bag liners come in many different materials, some of the most common being cottonsilk, microfiber and polyester. Microfiber is generally the bulkiest of these and while polyester can be the cheapest, it can also be less comfortable on the skin. The best silk sleeping bag liner can be quite expensive but luxuriously comfortable.

  • 1. Silk Liners are the lightest and most compact; they wick moisture well and dry quickly. Ideal (in mummy form) for backpacking or (as a Traveler) for hostel/budget hotel use. Sea to Summit’s Silk Sleeping bag Liners is now equipped with an exclusive Comfort Stretch Panel – a stretch panel which runs the length of the side seam and provides a greater level of comfort than has previously been possible in a silk liner. Also available as a double-wide version.


  • 2. Highly cost-effective solutions which, though not as light or packable as silk, still offer impressive weight and pack size. Cotton is a natural fibre known which delivers warmth and excellent comfort against the skin. Poly Cotton is a Polyester/Cotton blend, which combines the comfort of cotton with the strength and light weight of the polyester. Cotton liners weigh in at between 300 and 400 grams, whilst Poly Cotton liners come in at around the 300-gram mark. As with silk, both are quick and easy to wash and dry.


  • Warmth – do sleeping bag liners keep you warmer? Well, not all sleeping bag liners are designed to provide additional warmth and some materials do this better than others. Thermal liners are the warmest sleeping bag liner and are usually made of polyester. Microfiber liners can add considerable comfort but modest warmth.


  • Size – if you’re travelling you will want to save space. The most lightweight sleeping bag liner is usually made of silk or polyester. However, do note that most liners can be stored compactly and do not take up too much space at all, regardless of their material.

How to care for your sleeping bag liner:

This is the easy part. All of our liners are machine washable using standard laundry detergent. If you’re using a top-loader machine, it’s worth putting the liner in a pillowcase to stop the drawcord getting tangled in the impeller (the spiral plastic device at the centre of the drum). Just make sure to keep fabric softeners away from your liner – the softener will reduce the wicking performance. Air-drying is best, there’s no need to put a liner in a dryer.
