Decathlon Polyester Liner review: it’s cheap and basic but it does the job fine with no fuss

Decathlon Polyester Liner: first impressions

The pocket-friendly Decathlon Polyester Liner is ideal if you’re an occasional, casual camper, or if you’re shopping on a strict budget, for yourself or a teenage child embarking on an outdoor adventure. It’s also cheap enough if you want to try out a sleeping bag liner without investing in something too pricy.

This simple liner fits nicely into rectangular sleeping bags, offering good protection for their inner material and is easy to remove and clean on the go. 

It dries quickly and, because of its thin material, it can easily be washed in a sink. All of which makes it a good choice for hostel-hopping or hut-to-hut hiking when you’ll need to keep your sleeping bag clean.

Decathlon Polyester Liner: in the field

As well as being very reasonably priced and functional without fuss, the Decathlon liner also adds some warmth, so it’s a good choice for spring and fall nights outdoors. The downside, however, is that polyester isn’t very breathable – you may sweat and overheat on hot nights if you’re off to tropical countries or a summer festival. For those kind of scenarios we’d pick a lightweight silk or cotton design instead. 

This little liner weighs a respectably light 260g and packs down small enough to fit nicely into daypacks, so we like using it for hut-to-hut hikes and shorter wild camping weekends in cooler weather when the priority is staying warm and keeping a sleeping bag clean and in good condition. 

Decathlon call this a “great value-for-money liner”, and it’s hard to argue with that – at under $15 / £10, it’s a good addition to any camping kit collection.
