Gelert owned by Sports direct, so stuff that.
I didn’t buy it from them, I payed £17 instead of nearly £70, so I really couldn’t give a shit who owns the make! I used it at the IoW Festival last year, which wasn’t the warmest weekend, and for nine days in October last year, which was also pretty chilly at night, and that air mattress, along with a £40 Coleman bag I bought to replace the £19 Lidl one I’d stupidly left at home, and which turned out to be identical, meant I was really snug at night, and slept like a log. Obviously both are far too heavy and bulky for anything other than car camping, or using festival transport, but as far as value for money is concerned it’s an unbeatable combination for me; being comfy and snug for nine days in a tent was quite a stretch, never done more than three days before.
It was pretty chilly, I had a strong easterly wind blowing straight in at my tent from open sea, everything was covered in dew at night, but I was snug and toasty, what more could you possibly want for less than sixty quid?
