Cut to your bag's shape, or it bunches at the feet

The best sleeping bag liners for 2026

A liner does two jobs — it keeps body oils out of a down bag that cannot be washed often, and it adds a layer — and it works only if the shape matches the bag. A rectangular liner inside a mummy bag concertinas around the legs; a mummy liner in a rectangular bag pulls the corners in. Take the length and shoulder width from the bag specification, and check whether the liner has a shaped foot box. Fabric is the real decision. Silk is the lightest and the smallest packed, and it is delicate. Cotton is heavy, cheap and comfortable, and is what hostels ask for. Polyester microfibre and CoolMax dry fast and cost little. Fleece is much warmer and much bulkier. Where a maker states that a liner adds a number of degrees, that is the manufacturer's own claim, quoted here as such — it depends on the bag, the mat and the sleeper, and no standard governs it. Check the closure, since a zipped liner is far easier to get out of. We compare shape and dimensions, fabric, stated weight and packed size, any added warmth the maker claims, closure type, and washing instructions.

The ones worth packing

1. 

   YARVPUV travel liner, 220 × 90 cm, 512 g stated

   The heaviest of the seven liners here at a stated 512 g, and the one that turns into a full 220 × 180 cm blanket once the zip is run all the way round.

   Shape

   Not published on the listing — neither mummy nor rectangular is named; the maker states only that the liner opens out flat as a blanket

   Dimensions

   220 × 90 cm as a liner — stated; 220 × 180 cm opened out flat as a blanket — stated

   Fabric

   100 per cent ultrafine fibres — stated; the fibre itself is never named, so neither silk, cotton nor polyester is confirmed

   Stated weight

   512 g — stated, in the title and again in the first bullet

   Packed size

   22 × 22 × 5 cm — stated

   Added warmth the maker claims

   Not published on the listing — no degree figure and no warmth claim of any kind appears in the title or the five bullets

   Closure type

   A zip that opens completely — stated; the listing does not say which side it runs on

   Washing instructions

   Machine washable — stated, with a claim that it neither loses shape nor fades; no temperature is given

   Amazon reference

   B0DPB2YCL5 (same reference on 5 Amazon marketplaces)

   EAN

   0702602625628

   • Publishes weight, made-up size and packed size all three, which several liners on this shelf do not
   • The zip runs the whole way round, so the same piece is a liner or a stated 220 × 180 cm blanket
   • At a stated 512 g it is the heaviest of the seven liners here, against 128 g at the other end of the shelf

   Best for: Hut and hostel nights where the liner doubles as the only blanket you carry, and where 512 g in the pack is not the number that decides.

2. 

   Naturehike ultralight liner, 210 × 80 cm, about 128 g

   The lightest of the seven liners here at a stated 128 g, packed to 6 × 15 cm, and the listing never once says how it closes.

   Shape

   Not published on the listing — neither mummy nor rectangular is named anywhere in the title or the five bullets

   Dimensions

   80 × 210 cm opened out — stated, and also given as 31.5 × 82.7 in

   Fabric

   Felted nylon of low elasticity, described as a velvet-like weave — stated; the stuff sack is separately given as 10D fabric

   Stated weight

   About 128 g — stated, and also given as 0.28 lb

   Packed size

   6 × 15 cm — stated, and also given as 2.4 × 5.9 in

   Added warmth the maker claims

   No figure. The maker states the liner can improve the warmth and comfort of a sleeping bag; no number of degrees is published and no standard is named

   Closure type

   Not published on the listing — a zip is mentioned only when the washing label is described, and nothing says how the liner itself opens or shuts

   Washing instructions

   Machine washable — stated, with a washing label sewn where it will not catch; no temperature is given

   Amazon reference

   B0CRKNGVS9 (same reference on 5 Amazon marketplaces)

   EAN

   6976507661300

   • A stated 128 g and a 6 × 15 cm pack, and no liner in this hub publishes either figure lower
   • Both figures are repeated in imperial as well as metric, so nothing has to be converted or guessed
   • No closure is described at all, so it is unclear whether there is a zip, a tie or nothing

   Best for: Counting grams on a summer trek, where the liner is there for hygiene and the bag is doing all the insulating.

3. 

   Backpacker's Journey microfibre travel liner, 220 × 90 cm

   The only liner in this hub that publishes a wash temperature, and the only one that publishes its weight twice with two different numbers.

   Shape

   Not published on the listing — neither mummy nor rectangular is named; a pillow pocket is described, and nothing else about the cut

   Dimensions

   220 × 90 cm — stated, and called a comfort size by the maker

   Fabric

   100 per cent microfibre — stated in the bullets; the title separately gives the material as polyester

   Stated weight

   The listing publishes two figures — 168 g in the title and 186 g in the first bullet — and does not say which of them includes the compression sack

   Packed size

   14 × 7 cm including the compression sack — stated

   Added warmth the maker claims

   Not published on the listing — the bullets claim hygiene, breathability and tear resistance, and never mention warmth

   Amazon reference

   EAN

   4260619850038

   • Publishes a wash temperature, which no other liner in this hub does
   • The packed size is given with the compression sack counted in, not as a bare cloth measurement
   • Two different weights on the same listing, 168 g and 186 g, with nothing to say which is which

4. 

   Miqio 2-in-1 liner and 180 × 200 cm blanket

   A liner sold as two products: a 90 × 220 cm sleeve, or a 180 × 200 cm double blanket once the full-perimeter zip is opened, with the zip side chosen at purchase.

   Shape

   Not published on the listing as mummy or rectangular — the maker calls it 2-in-1 and gives a 90 × 220 cm sleeve that opens to a 180 × 200 cm blanket, and states the sleeve suits side sleepers

   Dimensions

   90 × 220 cm as a liner — stated; 180 × 200 cm opened flat, described as double bed size — stated

   Fabric

   Not published on the listing — the material is named only as Cotton Touch, and the maker states it is not cotton and dries faster than cotton; no fibre is named

   Stated weight

   390 g — stated

   Packed size

   Not published on the listing — a transport bag with a mesh panel is described so that damp can escape, and no dimensions are given for it

   Added warmth the maker claims

   Not published on the listing — the maker positions it for hot countries where even a light sleeping bag would be too warm, which is the opposite claim

   Closure type

   A full-perimeter zip that opens completely, supplied left hand or right hand and chosen at purchase — stated

   Washing instructions

   Washable, and stated to dry fast enough to be washed while travelling; no temperature and no machine or hand instruction is given

   Amazon reference

   B0744L8FKW (same reference on 6 Amazon marketplaces)

   EAN

   4260524230512

   • The zip runs the whole perimeter, so the same piece is a sleeve or a stated 180 × 200 cm double blanket
   • Left-hand and right-hand versions are offered, which matters if two are being used side by side
   • Cotton Touch is a trade name, not a fibre, and the listing never says what the cloth actually is

   Best for: Warm-country travel where a light sleeping bag would already be too much, and where the same piece has to serve two people as a blanket.

5.

   One of only two liners here that name cotton outright, at a stated 480 g and a 10 × 20 cm pack, with a pillow pocket and no fastening described.

   EAN

   8720938434419

   • Names the fibre outright — 100 per cent cotton — which four of the seven liners here never do
   • Publishes a packed size and a compression sack together, so the 10 × 20 cm figure is the real one
   • A stated 480 g, second heaviest of the seven here, which is the price of the cotton

   Best for: Hut and hostel nights where cotton against the skin is worth 480 g and the pack has room for a 10 × 20 cm bundle.

   Dimensions

   210 × 80 cm — stated in the title
