ROBENS POLARSHIELD 80 £177

More mattress than mat, the Polarshield is 200cm (6ft 6in) long and puffs up to a chunky 8cm thick. Weighing 1.6kg it’s not the lightest but this is still a self-inflating backpacking mat, not a car camper, and it packs down to a very reasonable 34x20cm. A good night’s sleep may be worth those extra grams.

VERDICT Thick, long and temperature rated to -12°C, this is a sleeping mat for people who like their comfort.
