  "title": "Baby sleep sacks with undyed or low-dye materials",
  "question": "Which baby sleep sacks use low-dye or chemical-free materials suited to sensitive skin?",
  "answer": "Swaddelini Organic Cotton Swaddle Sleep Sack: The majority of the swaddle is 100% raw, unadulterated organic cotton, made with a unique 3D knitting process rather than cut-and-sew. The colour is beige because the fabric is undyed — no dyes and no chemicals are used on it. Elastane is used in the Hug Technology and the diaper flap for stretch and recovery, so the swaddle is not 100% cotton.\nSwaddelini Bamboo Blend Sleep Sack Swaddle: The product is titled Swaddelini Bamboo Blend Sleep Sack Swaddle - Undyed (6-12LBS). The modal fabric is derived from bamboo using a primarily mechanical process rather than harsh chemical treatments. Maker says it has never had an issue with skin irritation, and children with extreme eczema found it helped them heal faster because they could not scratch their face at night.\nergoPouch Sleep Sack 2.5 TOG Willow: ergoPouch says all of its fabrics are dyed with non-toxic water-based dyes. The cotton is certified organic to the Global Organic Textile Standard (GOTS).",
