Weak points :


A high quality bag with impeccable finishes. I especially appreciate its light weight, compressibility and weight / heat. Perfect to place in his backpack and take her trek.

The side zip was enlarged on this new version passing of 1/4 of the size of the sleeping bag at topschoolsintheusa. This helps to better regulate the temperature is mild. Although I would have preferred a two-way zipper along the entire length of the bag to regulate the temperature in the foot.

Wide cut at shoulder height, facilitating movement. Despite the lack of collar, I never had the slightest feeling cold. A zipper allows to tighten the hood if the temperature decreases. This is also the only possibility of tightening. Everything has been designed to reduce weight while maintaining an efficient thermal protection.
This jewel has a high price but it is a luxury product!
