Size 1, 60 cm, for about age 1 - 7 months Size 2, 80 cm, for about age 6 - 18 months Size 3, 100 cm, for about age 18 months to 3+ years I love the purity of the fabrics and that is isn't superwash. The warmth of boiled wool is not at all like sweaty polyester. Wool breathes and regulates body temperature. I am convinced that my babies sleep better in wool and natural fibers, perhaps because they are neither too hot nor too cold in it. This really does have that Goldilocks effect of "just right". There is something amazing and superior about merino wool. The organic cotton lining inside is soft, too. This is not intended as a diaper cover. It is clothing. Don't confuse this with thin, lightweight washable wool sacks. This wool is more substantial. I keeps its shape and lays where it ought to be as baby moves around. It contains a lot of wool. The weight is just right for both warmth, breathability and a feeling of security. Babies really do soothe easily in wool! The front zipper opens up all the way for easy access to baby. The top of the zipper is covered. Hand wash only. Made in Germany. All of our stock has the zipper cover near the baby's chin. These are much nicer than they look in the pictures. Grey shown on the baby is size one. What is Boiled Wool? Boiled refers to the way the wool is processed. It is not the same as "superwash" wool which involves chemicals and coatings. Boiled wool is a versatile fabric that has been used for centuries. Boiled wool is created by a process called fulling, which involves washing and agitating the fabric in hot water. This process causes the wool fibers to shrink and interlock, resulting in a denser wool that is soft and not itchy. GOTS certified wool and organic cotton means no worries about safety. Warmth: Boiled wool is an excellent insulator yet it doesn't get too hot because it breathes Breathability: allows moisture vapor to escape Water resistance: The interlocked fibers of boiled wool create a natural barrier that is resistant to water penetration. This helps keep sheets dry in case of a leak. Durability: The fulling process makes boiled wool more durable and more resistant to pilling. Pass this lovely item down to future children. No polymer resins: Wools that can be machine washed on warm have been processed in a different way than this item. With the other kind, the fibers may be coated with a thin polymer resin or the fibers have been treated with chlorine to remove their scales. The polymer resin on superwash is likely a thin coating of a plastic-like material applied to the wool fibers in order to prevent it from felting when washed. Boiled wool is not coated. The wool is just wool and the cotton isn't coated either. Disana GOTS certified wools must be hand washed Washing is infrequent. Hand washing is easier than it may seem. I, Karen, really enjoy hand washing this lovely garment once in a while. Wash only if very soiled, otherwise just air out and re-use it. That's even easier than machine washing. If there is a leak and the cotton interior gets wet, just turn it inside out and rinse the cotton out well. It's not that hard and you can enjoy that the sheets stayed dry. Warm boiled wool on the outside, extra-fine organic cotton on the inside. Our boiled wool Disana sleeping bag combines the best of both natural fibers. The outside, made of soft new boiled Merino wool, provides plenty of warmth. Wool is very good at balancing out the temperature; you are usually not too warm or too cold wearing it. An extra fine organic cotton lining on the inside allows the child to sleep in peace. Thanks to the long zip in the front, the sleeping bag can be opened wide. This makes it easier to place your child inside when she is asleep. A priceless advantage for little ones after a long day of adventures, play and discovery.

Disana brand page Note from Karen: Green Mountain Diapers does not sell anything made with superwash wool. Why? Purity. Coating wool with silicone or polymer resins is not the same as boiled wool. Besides, when I wash a product with superwash treatment, I can smell the chemical odor. (My very sensitive sense of smell is my "superpower"). Plus, I enjoy hand washing wool. It doesn't need to be done often, but it is satisfying and enjoyable when I do hand wash my wools. If I'm going to choose natural wool, I want it to actually be a natural fiber, not just made from a natural fiber that has then been chemically processed and changed.
