  "question": "What fabrics are baby sleep sacks made from?",
  "answer": "Swaddelini Cotton Sleep Sack Swaddle: The majority of the swaddle is 100% raw, unadulterated organic cotton, made with a unique 3D knitting process rather than cut-and-sew. Elastane is used in the Hug Technology and the diaper flap for stretch and recovery, so the swaddle is not 100% cotton.\nTiny Twinkle 2-in-1 Baby Sleep Sack - 1.0 TOG: The manufacturer describes the fabric as soft, breathable micro-fleece. The fabric blend is 95% cotton and 5% elastane.\nCoccoli Modal 1.5 TOG Sleepsack: It is made from 95% modal and 5% spandex.\nAngel Dear Sleep Bag - Shark and Friends: Made from smooth and breathable viscose from bamboo fabric.\nQuincy Mae Bamboo Sleep Bag: It is described as a comfortable everyday baby essential made with soft bamboo fabric and an easy-to-wear silhouette for cozy daily use. The shell is 94% viscose from bamboo and 6% elastane; the filling is 100% polyester.",
