Best Sleeping Bag Liners for 2017


Alps Mountaineering Mummy Liner

Alps Mountaineering Mummy Liner

A sleeping bag liner is a fairly thin and lightweight cloth sack designed to be slipped inside a sleeping bag. It keeps your sleeping bag clean and free of body oils and thus increases its thermal efficiency since body oils decrease the loft and warmth of a sleeping bag. A sleeping bag liner can be also used without a sleeping bag – like for example for sleeping in mountain huts which typically provide blankets but not bed linen or when travelling and sleeping in hostels of questionable cleanliness (bedbugs). Those who use a quilt (a super lightweight sleeping bag without a zipper which leaves your back in direct contact with sleeping pad) often pair it with a sleeping bag liner as it increases the comfort of this minimalistic sleeping setup. Another benefit is that using a sleeping bag liner allows you to wash your sleeping bag less frequently – which increases its lifespan and decreases the degradation of sleeping bag’s insulation. In very warm weather, when you have your sleeping bag partially unzipped, a sleeping bag liner also protects you against bugs and mosquitoes.

A sleeping bag liner can also add warmth to your sleeping bag, depending on its material. However, as sleeping bag liners have to be fairly thin to fit into a sleeping bag, they add fairly little warmth and therefore they are not the best option to increase the insulation of a sleeping bag. Bag liners made of fleece are for example thermally inefficient (heavy for the warmth they provide) and thus it’s better to wear a fleece jacket and pants during the night rather than using such liner. The same goes for bag liners with synthetic insulation – you can use insulated pants and jacket instead.

Due to the reasons mentioned above, we only included silk and synthetic sleeping bag liners in this review. They provide very little warmth, but are super lightweight and well-packable. Furthermore, they are also breathable, quick-drying and moisture-wicking.

1. Buying a Sleeping Bag Liner  – What is important?

Material:

Sleeping bag liners can be made of silk, synthetics (microfiber, polyester etc.), cotton or fleece. Some bag liners are insulated, meaning that synthetic insulation is sandwiched between the nylon shell and lining.

Silk Bag Liners (included in this review):

Sleeping bag liners made of silk are super light, well-packable and pleasant to the touch. Silk also dries very fast and doesn’t feel clammy against the skin when wet/moist. It is also naturally antimicrobial and can be knit into very thin fabrics. Silk bag liners provide very little warmth but they do protect your sleeping bag against body oils and dirt.

Synthetic Bag Liners (included in this review):

Sleeping bag liners made of synthetic materials are also light, well-packable and dry very fast (depending on the thickness of the fabric). However, they are more plastic-like to the touch than silk bag liners and not naturally antimicrobial. These liners provide very little warmth but are very durable and offer good protection against body oils and dirt.

Cotton Bag Liners (not included in this review):

Cotton sleeping bag liners are not the best option for hiking/backpacking as cotton is much heavier than silk or synthetic materials. Furthermore, it also dries very slowly as it absorbs a lot of moisture. Like silk and synthetic bag liners, cotton bag liners provide very little warmth.

Fleece Bag Liners (not included in this review):

Fleece bag liners are primarily designed to add warmth to a sleeping bag. However, polyester fleece is not the most thermally efficient material and thus such bag liners are typically heavy and bulky. As explained above, you will probably be better off wearing a fleece jacket and pants during the night.

Insulated Bag Liners (not included in this review):

Insulated bag liners look like super thin sleeping bags and feature synthetic insulation such as PrimaLoft. They are more thermally efficient than fleece bag liners but still heavy and bulky. As we mentioned above, you will probably be better off wearing an insulated jacket and pants during the night.

Shape:

Sleeping bag liners are usually available in two different shapes – mummy and rectangular. If you are planning to use the bag liner with a sleeping bag you should go for a mummy shape so that it will fit nicely into the sleeping bag.

Size:

Some sleeping bag liners are available in several sizes which differ by length and rarely in width. Choose the size according to your body height.

The Cocoon Ripstop Silk Expedition sleeping bag liner is due to its durability and low weight very popular among mountaineers and hikers. It is made of silk which is reinforced with interwoven threads at regular intervals (ripstop) for better tear resistance. The material is well-packable, breathable, moisture-wicking and quick drying. The sleeping bag liner is available in three different sizes (S, M and L) for good fit. Cocoon claims that this bag liner adds up to 5°C of extra warmth to the sleeping bag. However, it’s important to note that such ratings do not apply for everyone (some people get cold faster than others). The sleeping bag liner also features a drawstring hood and comes with a waterproof stuff sack for easy packing (when packed it measures only 13 x 6 cm). It fits perfectly into technical (mummy) sleeping bags.
