This innovative SNOO sack is the world’s first 5-second swaddle, letting you easily snuggle and wrap your little one so they can be soothed and feel secure. Tuck its special swaddle wings to the sides of the SNOO Smart Sleeper Bassinet (sold separately) to keep them lying flat on their back all night long. Made with pure organic cotton, it’s a safe choice for your baby.


  • Special swaddle wings keep your baby safely on their back all night long.
  • Open mesh helps prevent overheating.
  • It is hip safe so it lets you see that the hips are always in the right position.
  • The Large and Medium SNOO Sacks have buttons that allow for the arms to be out of the swaddle.
  • Certified GOTS (Global Organic Textile Standards): This product meets the gold standard of textile production – it exceeds organic fiber requirements, contains no restricted chemicals and meets strict social responsibility standards.


  • Made of 95% organic cotton, 5% spandex and the mesh is made of 100% polyester. Organic cotton is grown without the use of toxic and persistent pesticides and synthetic fertilizers.
