It is sleeveless so a baby sheds heat rather than trapping it, and a two-way zipper runs the length of the bag so a diaper change takes seconds without fully undressing the baby. The neck and arm openings are bound in soft fabric rather than serged edges, and are cut snug.\u003c\/p\u003e\n\u003cp\u003eThe fabric is Tanboocel, a branded bamboo viscose blended with cotton (70% rayon from bamboo, 30% cotton) made through a closed-loop process that is third-party verified, with a lower water and chemical footprint than generic bamboo rayon. It is noticeably softer after the fifth wash than on day one, the opposite of how cotton tends to age, and it takes the dryer better too, with less pilling and shrinkage over repeated cycles. The fabric is OEKO-TEX Standard 100 certified and is tested to U.S. flammability standards (16 CFR Part 1610), CPSIA, and ASTM standards. Wash cold with like colours, tumble dry on low heat, use only non-chlorine bleach, and skip the dry cleaner and iron.\u003c\/p\u003e\n\u003cp\u003eThis weight is meant specifically for warm rooms; it is not intended as a general-purpose, all-season bag, so a warmer-rated bag is worth having on hand for cooler nurseries.\u003c\/p\u003e\n\u003cp\u003eDesigned to be worn over a bodysuit or sleeper.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-way zipper opens from the bottom for diaper changes\u003c\/li\u003e\n\u003cli\u003eSleeveless design to avoid trapping heat\u003c\/li\u003e\n\u003cli\u003eOpen-weave Tanboocel muslin keeps air moving through the night\u003c\/li\u003e\n\u003cli\u003eNeck and arm openings bound in soft fabric, not serged edges\u003c\/li\u003e\n\u003cli\u003eSnug-cut neck and arm openings for a safer fit\u003c\/li\u003e\n\u003cli\u003e0.5 TOG weight, rated for warm nurseries between 75 and 81°F\u003c\/li\u003e\n\u003cli\u003eMachine washable and dryer safe\u003c\/li\u003e\n\u003cli\u003eOEKO-TEX certified fabric\u003c\/li\u003e\n\u003cli\u003e70% rayon from bamboo (Tanboocel), 30% cotton\u003c\/li\u003e\n\u003cli\u003eTanboocel bamboo viscose made through a closed-loop, third-party verified process\u003c\/li\u003e\n\u003cli\u003eSoftens after repeated washing, unlike cotton which can stiffen over time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTrustScore\u003c\/h3\u003e\n\u003cp\u003eTrustScore is Birch's proprietary rating, from 0 to 100, built from 50+ signals that reflect what actually matters to parents — safety, materials, recalls, certifications and quality.
