Minus one star because the zipper closes upwards, making it difficult to change. It is probably an old design since another one I bought from the same company's official dealership closes normally downwards. It is true that you need a larger size.

Not worth buying. The quality is good, but they are extremely short. The 3-9 months size, we barely managed to wear it until 5.5 months.

We used it from newborn to 4.5 months, very warm and user-friendly. Very comfortable for the baby. The swaddling is very practical, without struggling with swaddling blankets or covers.

I bought 2 grobag sleeping bags which I never ended up using as they were too tight. They were really suffocating, even though my baby was within the weight range for their age.

The sizing chart does not match reality. Very tight, especially in the upper part with difficulty closing the zipper.

The sizes are all over the place. It says 3-9 and 5.4 to 8 kilos... My baby hasn't even entered the 3rd month yet and weighs 5.8 kilos, and the sleeping bag doesn't even close up to the neck. Such a shame because it seemed really nice to me and I had ordered 2! Money wasted...

The baby gets cold with the suggested clothing through the sleeping bag so we wear an extra onesie but here where we live it's very cold. We got a 2.5 tog for winter. Very good quality. We actually used it until nine months. If the prices were a little more affordable, I would definitely buy again from the same company.

The colors and design are fantastic. The quality is also great. However, I had to return it for an exchange. I bought size 3-6 months for a 1-month-old baby and it was too tight!!! I exchanged it for size 6-9 months. I believe it won't fit the baby until they are 6 months old. Very good quality and quite warm, but there is something wrong with the sizes, so be careful!
