  "title": "Light sleep sacks for hot summer nights",
  "question": "Which sleep sacks are light enough to use on a hot summer night?",
  "answer": "Kyte Baby Printed Sleep Bag in 0.5 tog: The review names the Kyte Baby 0.5 TOG as its best warm-room/summer pick, for rooms 74 degrees Fahrenheit and up. The maker describes the fabric as highly breathable.\nergoPouch Sleep Suit Sack 0.3 TOG Berries: The garment's rated warmth is 0.3 TOG. A 0.3 TOG version was used with the brand's temperature guide in a hot, uncooled home and the baby stayed comfortable without needing fans or air-conditioning.\nKyte Baby Sleep Bag in Golf 0.5: The 0.5 TOG version is recommended for warm rooms, upper end of the recommended room-temperature range, or babies who sleep hot. The maker describes the fabric as highly breathable.\nergoPouch Cocoon Swaddle Sack: The page states the product is 0.2 TOG. A tester used it in a warm maternity ward and found the lightweight 0.2 TOG kept the baby snug without overheating. Several users report the swaddle creeping up over the baby's face when the arms are in, and describe this as a suffocation risk even in what they believe is the correct size.\nKyte Baby Sleep Bag in Starry Icon 1.0 tog: A warm-sleeping baby stayed comfortable without overheating, even in summer, at the 1.0 TOG weight for rooms around 69–73 °F. This is a 1.0 TOG bag, which the maker says suits a nursery at 21–23 °C (69–73 °F). Bamboo is described as delicate: washing hot or with velcro and rough fabrics can make the bag pill, so cold delicates and hanging to dry keep it looking new.",
