Engel makes the perfect sleep sac. 100% Organic Merino Wool Terry is lightweight yet warm. Wool is warmth and moisture-regulating, keeping baby warm in the cooler months and cooler in the warmer months. A natural warmth is generated without heat build-up, regulating humidity, and supporting a healthy skin climate.
Wool absorbs up to one third of its own weight in moisture and depending on external conditions, is able to return it to the environment. Synthetic clothes may look the same but do not allow the skin to breathe and accumulates uncomfortable heat and moisture.
Unpleasant odour comes from bacteria which develops quickly in the moisture. Animal fibres, like wool and silk, take up the moisture and wick it away by airing; thus bacteria cannot settle as easily. Crop fibres such as cotton as well as synthetics hold bacteria.
The sleep sac has a zipper at the bottom for diaper changes. Wash by hand or machine washable on gentle cycle in warm water. Size 1 fits up to size74/80, size 2 fits up to size 86/92.
