What this listing puts on record

A 100 per cent cotton liner given as 210 × 80 cm at a stated 360 g, packing to 9 × 22 cm in an elastic four-way stretch mesh bag, with the zip on the left on the blue version and on the right on the red, and two units stated to couple together.

The coupling, which nothing else here offers

Order one of each colour and the pair zip into a single wide liner. It is a plain, useful idea, published plainly: blue is left, red is right. Nothing else in this hub describes joining two units at all.

Lighter cotton than the alternative

360 g. The other cotton liner in this hub is a stated 480 g. Both name the fibre outright, which already puts them ahead of the four listings here that describe their cloth with adjectives.

The size to check hardest

210 × 80 cm. That is the shortest and the narrowest cut published in this hub — four liners here are 220 × 90 cm. Ten centimetres of length and ten of width sound like nothing until you are inside it. Measure your own bag before ordering.

What the maker says about moisture

The bullets argue that a sleeper gives off up to 1.5 litres overnight and that cotton takes it up where a synthetic leaves you feeling damp. That is the manufacturer’s case for its own fabric, quoted as such. What follows from it in practice is a liner that dries more slowly than the microfibre and silk options here.

The zip that is only half described

Which side it is on: published, and useful. How far it runs: not published. Whether the liner opens flat: not published either.

    • 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.

    • 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

    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.
