Knit jacket made of 100% cotton in our workshops in Barcelona. The fabric is very soft and there are no seams on the inside, making it easy for baby's skin to never scratch or itch. In addition, since it has no seams, it adapts perfectly to the baby's body. It is a garment that provides incredible warmth. The buttons on the jacket are made of natural olive wood. Cold wash and do not tumble dry. Made in Spain.
