Great Bag at a Great Price

Circa £30 on sale, went to Peak District bikepacking Mid Oct. 8 - 10c at night. Slept in nothing but pants. A genuine 3 season bag that doesn't weigh much, packs small, perfect bag even at full price.

Highly recommend

Very light very small but extremely warm. I've only used in the summer but been used in both hammcok and bivy. Excellent bag if your are looking something lightweight but still toasty

Freezing at 6c

Used when the temperature dropped to around 6 degrees Celsius overnight. I wore leggings, wool pants, wool cardigan and down jacket and I was still freezing. Used with the Therm-a-Rest Prolite sleeping mat which felt warm to the touch, so it was definitely the sleeping bag that was the issue. I don’t know where they get their comfort rating from, but take it with a huge grain of salt. This sleeping bag is best used above 10 degrees Celsius in my opinion.

Remarkably lightweight

What more could you ask for. Just over 1kg in weight, packs down small and lovely and warm for early Spring camping.
It’s nicely shaped allowing for elbow movement and not too tight on the legs. The hood pulls in nice.
I bought both the 200 and the 300 and they are both great.
