I must admit that I am a fan Alvi - when it comes to sleeping. My now has 12-month-old son has never slept in a different sleeping bag. And also this beautiful summer sleeping bag from Alvi is super! Whether my son has slept only a Kurzarmbody fact or even a pajama, he was always cuddly packed without sweat. The sleeping bag is worth the money for sure! PS: A friend of mine bought the same sleeping bag for her son and was 100% satisfied.
