I had bought this sleeping bag in a different design and because it worked well for us, I decided to buy it again.
1. There is no summer/winter option, they are all 3.3 tog, only the designs and colors change.
2. It requires a lot of attention when ironing because the inner material is of poor quality synthetic and melts even though the instructions do not mention that it should not be ironed.
3. BEWARE, check all the buttons and seams very carefully before putting it on the baby. When I tried to button the buttons on the shoulders, I felt something scratching my hand and when I looked, a sharp piece of metal was sticking out of the button.
No safety check from the company before the products are released on the market and it's a shame because I have already bought many, including the crib where the baby sleeps.
I give it two stars instead of one because the other sleeping bag that doesn't have manufacturing issues worked well for us and covers a wide range of temperatures without the baby getting cold or overheated. I would describe the quality as average, even if we exclude the unfortunate incident with the button.
But safety above all, it goes without saying that I would not buy it again and I definitely do not recommend it to anyone for their baby.
