Very light and compact. Enough space. Pity that one cant fold it it back into it's original stuff/coke can:-o) sack. Need to cut off that section now. Space wasted, although it looks cool on the shelve for buying. The hood or cowl section is a little to short in my opinion. As I moved during the night the two ends continuously opened up, causing cold air and water to come in. Maybe Velcro or a waterproof zip could be installed to join the pieces together... The idea that the cowl or hood should come with riser bar or pole, because it lies flat on your skin and cause serious condensation. This might lift the prize, but would be more practical. I won't recommend this for a survival situation. The other model will be your better option.
