Cosilana Natural Wool Terry Sleep Sack
The ideal sleeping bag for peaceful nights
Imagine a peaceful night where your baby sleeps comfortably, wrapped in natural, breathable softness. The Cosilana Natural Wool Terry Sleeping Bag was designed to meet this essential need for well-being and safety. Made in Germany from pure wool without any chemical treatment, it offers a healthy environment that respects your child's delicate skin. Its major asset? Effective thermoregulation, ensuring soft and peaceful nights, season after season.
Between German craftsmanship and noble materials
The Cosilana Wool Terry Sleeping Bag is the result of solid expertise. Cosilana, a renowned German brand, uses natural wool selected for its softness and durability. Wool terry is distinguished by its looped structure, which retains heat homogeneously while allowing baby's skin to breathe. This material is particularly appreciated in spring, summer, and autumn, thanks to its thermoregulatory properties which keep baby warm without the risk of overheating.
The cut is designed to free your child's movements during sleep, while providing a reassuring sense of support. Adjustable shoulders and a discreet closure help you easily put on or take off your baby, even when sleeping. In addition, the natural shade of the sleeping bag gives it a minimalist and timeless style, which blends perfectly with any wardrobe or room decor.
The wool used comes from farms that practice environmentally friendly agriculture and animal welfare. Thus, you offer your little one an ecological product, free from harmful treatments, for an ultra-soft touch and incomparable comfort. This attention to detail is what makes Cosilana famous and explains the growing enthusiasm of parents wishing to combine quality, ethics and practicality.
The sleeping bag is available in 2 sizes:
- 66cm - size 1: 74/80cm (sleeping bag length: 66cm, from shoulders to feet)
- 81cm - size 2: 86/92cm (approx. 81cm long)

Care and usage tips: preserving the natural beauty of wool
To preserve all the softness and thermoregulatory effectiveness of the Cosilana Sleeping Bag, we recommend hand washing or machine washing on a wool cycle, avoiding any abrupt temperature difference between washing and rinsing. The use of a special wool detergent and the absence of aggressive spinning will preserve the suppleness of the fiber. Dry flat, in the open air if possible, to avoid deforming the fabric.
Proper care guarantees the longevity of this essential baby trousseau item. To learn more about the best washing practices and the unique properties of merino wool, consult our guide to wool.
