I got this after comparing with other products that decathlon has and I am pretty satisfied with it. It is light and compact(though not as much as the helium 0) and offers good comfort at close to 0°. Proved really comfortable at high altitude treks, though the real test will be the chadar trek. However, I am not happy with the cover that it comes with. The stitchings on the cover is flimsy and can rip off easily if you are not careful. Otherwise it is a great product.
Spacious and comfortable with the extra padding and all. Kept me warm. A tad heavy but worth it.
