Positive: It really takes up very little space and I don't know if there is another sleeping bag that is so compact.

Negatives:
- I am 1.75 and I believe that it barely fits me. If someone is over 1.80 they should go for something else.
- Its width is small, I could barely fit both of my hands (ended up sleeping with my hands outside the sleeping bag).
- The product image has nothing to do with reality (it is made of the same fabric as all sleeping bags, while in the picture the material looks thicker).

I don't regret buying it, but if you are looking for something for more extreme situations, it is good to go for something else (I intend to use it indoors in shelters so that I don't have to carry sheets)
