SEA TO SUMMIT ULTRALIGHT INSULATED MAT £120

USED FOR 4 months

A couple of inches. That’s all it boils down to – the difference between a torrid sleepless night and some solid shut-eye on a camping trip. And so, the few-inches-thick sleeping mattress you choose to take with you is crucial.

I’ve been sprawling on this comfy mummy-shaped Sea to Summit mat since early April and, in some pretty testing overnight conditions, it’s stood up to the test superbly. With a packed weight of 480g and dimensions of 10x23cm in its stuffsack, it goes pretty much unnoticed in my rucksack. Blowing up the mat takes under a minute using the Airstream Pumpsack, which is cleverly

integrated into the stuffsack.

Comprised of 181 air-sprung cells containing a single layer of loft insulation, the UltraLight prevents heat loss through your body to the ground. A heat-reflective outer fabric also radiates warmth. I’ve found this to be ideal for early spring through to late autumn – especially when used with a warm sleeping bag.

It can be slightly noisy when you move on it and at £120 it’s not cheap, but if you’re a keen camper this would be a worthwhile investment.
