These are in excellent pre-owned condition - photos to come. They are hard to part with but my son has grown out of them. Purchased from a UK site called Mama Owl; they’re sold out there. Size 4-5y (110-116cm). “These Boiled wool dungarees/trousers are one of our all time favourite MamaOwl products. 
Disana produce this style exclusively for us and now we can offer them in a wide range of colours. This style is fairly generous and versatile in use. Perfect over leggings and a sweater in the milder months, and under the jacket in the winter. 
We love this timeless style and that they provide our kids with the perfect amount of protection and flexibility for outdoor play. Disana’s boiled wool trousers are designed to be warm and sturdy, yet lovely and soft. Cut especially high at the waist, they keep your child’s back and tummy warm and cosy. The wide cut leaves plenty of space for warm clothing underneath. Two braces help keep everything in place, and the pocket can be filled with treasures. With their reinforced knees and bottom, these boiled wool trousers are good for crawling and exploring.” Made from 100% Organic Merino Wool. Made in Germany.
