Sleep Bags

Comfortable sleep for babies depends on the right tog rating for the room temperature. A 0.5-tog bag suits warm rooms above 24°C. A 1-tog bag covers most of the year at 18–22°C. A 2.5-tog bag is designed for cooler rooms below 18°C. Next's baby sleep bag collection on this page features 105 styles across 0.5 to 2.5 tog ratings, from Next's own range and JoJo Maman Bébé. Sizes run from one-size newborn through 3-6 months, 9-12 months, 12-18 months, 1.5-2 years, and 2-3 years. Cotton (including 100% cotton and embroidered muslin) is the primary fabric across the range. Most styles sit between €22.50 and €37 per bag, with prices varying by size.

Why Sleep Bags Are Used Sleep bags replace loose blankets in a baby's cot, reducing the risk of overheating and of bedding covering the baby's face during sleep. They are widely used as a safer alternative to duvets and sheets for babies under 12 months, and help establish a bedtime routine — putting the sleep bag on signals that it is time to sleep. Understanding Tog Ratings Tog measures thermal resistance: the higher the tog, the warmer the bag. A 0.5 tog sleep bag suits warm summer nights and rooms above 24°C. A 1 tog bag works for most of the year in typical Irish homes kept between 18°C and 22°C. A 2.5 tog bag provides warmth for cooler rooms below 18°C and winter nights. Next's range on this page covers 0.5, 1, and 2.5 tog options. Materials Cotton is the primary fabric across the range — breathable, soft against sensitive skin, and machine washable. The materials filter on this page lists Cotton and 100% Cotton, with several styles also offered in embroidered muslin (a loose-weave 100% cotton fabric). For specifics on filling and outer fabric composition, check the individual product page. Sizes and Age Ranges Sleep bags are sized by age rather than body measurement. The size filter on this page covers one-size (newborn), 3-6 months, 9-12 months, 12-18 months, 1.5-2 years, and 2-3 years. Prices vary by size — larger sizes cost more — which is why most products on this page show a price range rather than a single price (for example, €25–€30 for the 1 tog Sleeveless Baby Sleep Bag depending on size). Prints and Colours Designs cover gender-neutral, boys', and girls' options across 14 colour categories. Visible prints include safari animals, dinosaurs, florals, farm scenes, jungle, embroidered muslin, mini turtles, sea print, tropical, gingham bows, pineapple, fruits, checkerboard, and embroidered bunny and bear designs. Most prints are available across multiple tog ratings, so you can maintain a consistent look across seasons.
