The ErgoPouch Cocoon is a 2-in-1 baby swaddle sleep sack and sleeping bag crafted from natural materials. This versatile design allows parents to safely and easily swaddle newborns from birth, while also functioning as a traditional arms-out baby sleep sack for infants who prefer not to be swaddled. The Cocoon features a 2.5 TOG thermal rating, providing optimal warmth for cooler environments and making it suitable for babies aged 3-6 months. Constructed from GOTS-certified organic cotton with a touch of elastane, the fabric offers excellent stretch that limits the startle reflex while allowing necessary movement for healthy development. The stretchable material ensures complete chest expansion during breathing and permits hand movement for self-settling. The bell-shaped bottom design is approved by the International Hip Dysplasia Institute as hip-healthy, promoting proper joint development in hips and shoulders. A two-way zipper facilitates quick diaper changes with minimal sleep disruption, while snap-button shoulders enable easy transition from arms-in swaddling to arms-out sleeping when babies show rolling signs. The soft, breathable organic cotton is certified non-toxic, dyed with water-based colors, and gentle on sensitive newborn skin, including eczema-prone skin. The sleep sack features a secure neck, shoulder, and chest fit to prevent slipping, with guidance for proper sizing based on baby weight. Available in oatmeal marle color, this unisex sleep sack measures 70 cm in length and is designed for babies weighing 6-8 kg. Each purchase includes a practical room thermometer and dressing guide to help parents maintain appropriate sleep temperatures throughout day and night. Machine washable for easy care, this sleep sack eliminates the need for loose blankets in the sleep environment.
