Light, comfy, but not 4 season

Rated as 4 seasons and a comfort temperature of -1, yet still cold in the Cotswolds in June... and I'm not someone who feels the cold much

Super cosy yet super compact

Firstly I’d like to point out I HATE being cold.
I bought this for a trek I did in America. I chose this one due to the great reviews.
When it arrived I thought I had been sent the wrong item as it was really thin.
My first stop was Yosemite, there was still snow when I went and it was pretty cold in the evening, around 3 or 4 degrees.
Still not liking the cold I was a bit worried about going to sleep in this really thin bag.
As soon as I got in it was as though the cold did not exist I was actually amazed and I was super cosy all night.
Next stop was at the Grand Canyon at -5 and I was still super cosy.
I also camped at the Colorado river which was much warmer ( 15 degrees) and I wasn’t too hot in it either.
If you are looking for a decent/warm sleeping bag then I would recommend this one.
It even fit perfectly in the lower compartment of my rucksack which was ideal as I only took hand luggage with me for the trek.
It’s also easy to roll back up and put back into the stuff sack.

Great bag

Have bought it on offer and very happy with the purchase. My son used this bag for DofE expedition this April and has been very impressed with it. He said that he did not feel cold at all, easy to fold and requires little space to carry it.

Great sleeping bag

Used this bag in the Scottish Highlands in early April. Didn't feel cold once, was well impressed with this bag as it is very reasonably priced and packs up really small. Would definitely recommend.
