Thicker than expected

The sleeping bag looks exactly as shown. Quality is fully in order. The fabric is a little stiff but is determined by the time soft.

However, I am surprised very, why this sleeping bag is both front and rear gefuttert since our first sleep sack (also 2.5 Tog, the design "Giraffe") is only gefuttert front. This is so much thicker than our first sleeping bag. I do not know which of the two is now sleeping really the 2.5 Tog, but it was okay to have two different thicknesses sleeping and had therefore not sent him back. The advantage of the thicker sleeping bag is that it's back and keeps warm when the baby is like turning on the belly. The disadvantage in turn, that the bag is a bit stiffer and turning in his sleep is not so simple.
