Too Thin. Maybe one third volume of the picture in the ads.
Received in 6 weeks to Romania, not tested yet, just unboxed. The sleeping bag looks and feels great, as expected from Naturehike: attention to details, soft and pleasant material. Baffle-box construction! Described as ~910g, it's less than 800g on my scale (see photo). Hopefully, it's the materials that make it lighter, not the goose down (which should be 400g, 750FP). The second picture is a visual comparison with an Aegismax SP II, that has only 320g of 600FP goose down. Maybe it's just an optical illusion, but I really expected the Naturehike to be fluffier, so I give it only 4 stars.
