I haven't tried in the real world yet but very good first impression, minimal packaging but the product was well protected. The goose down filling doesn't smell as certain customers noted, it only smells like new plastic, so nothing unexpected.
Good quality for the price. Nice zipper, modern velcro and pleasant material. Recommended. Probably the best 3 season bag (price/performance). Arrived in 23 days to Europe. Good communication by the seller.
