I'm happy with this sleeping bag.
I used it at my hiking trip in lake district in early November and I didn't feel cold at all.
I like the mummy shape but i can't move a lot in the sleeping bag as it's a bit narrow.
The 'compression sack' storage bag is helpful to further reduce the size of the sleeping bag to a small ball, which is excellent for backpacker like me.
I found the info printed on the storage bag is quite useful too.

Overall, it's a light, small and worth buying sleeping bag.

Advantages: Very lightweight, packs down small

Disadvantages: A but narrow and not much movement allowed in the sleeping bag

I bought this sleeping bag to take with me on the Camino de Santiago 800 km walk. Weight is critical and it packs up small in the rucksack.

Advantages: Very light and small but is 2 season.

Disadvantages: None identified

I bought this sleeping bag for travelling around Arizona/ California and Nevada in September 2013 and my main criteria when searching was that the sleeping bag be lightweight and pack small as space was limited in my bag. On both counts it is great and I would recommend.

In terms of comfort, I tend to curl up in my sleep and move about a bit. Being quite narrow in the mummy style I didn't find the sleeping bag the most comfortable but that is a personal preference - you will never get a super comfy spacious sleeping bag that also packs up as small as this one, so if size and weight is your number one priority I would highly recommend.

Advantages: Very lightweight, packs down small

Disadvantages: Bit narrow if you tend to move about a bit in your sleep

I'm very happy with this sleeping bag.
I used it at a festival in Ireland in September when the temperature went down to around 8C and I wasn't cold at all.
The mummy shape is fine for me but may not suit all.
One of the best features of this sleeping bag is the 'compression sack' storage bag enabling you to tighten the straps when the sleeping bag is inside. You can then reduce the size of the bag to a small ball. This makes it ideal for packing inside you backpack or carry-bag.
Another neat touch is the basic specifications are printed on the storage bag. Handy in case you forget the temperature range or weight etc.

Overall, a good product that ticks all the boxes I was looking for.

Advantages: compression sack
