The ideal temperature and comfort throughout the night are key factors in avoiding unnecessary awakenings of a baby because they won't get cold or hot, leading to better quality and longer sleep. 

Often, the temperature of a room changes during the night, but safe sleep guidelines warn against adding a blanket over a baby's sleeping bag, as this is dangerous, and changing clothes can wake the baby. 

For this reason, in collaboration with sleep scientists and a certified pediatrician at Northumbria University, the All-Season Grobag sleeping bag with dual Tog unit was created. It is suitable for all seasons and temperatures from 14-27+°C. It features a removable lining that can easily convert a 2.5 tog sleeping bag to a 1.0 tog. 

If you need to adjust the baby's temperature during sleep, you can add or remove warmth using the external zipper, without disturbing the baby's sleep.

The breathable material placed in areas where babies usually get warm helps to effectively release excess heat from their bodies, supporting their natural temperature regulation and ultimately helping them stay comfortable all night. The All-Season sleeping bag is designed for sleeping with arms out and should not be used as a swaddle for swaddling.

• Developed in collaboration with sleep scientists: The All-Season sleeping bag is designed to keep the baby safe and comfortable - 85% of babies sleep better* with Tommee Tippee Grobags. (*Source: Independent study of 297 mothers in the UK using a Grobag (MumsViews - April, 2021)
• Allows hands to be free for self-regulation of body temperature. 
• Perfect SnugFit: The hourglass shape creates an even better fit and helps ensure that the baby's legs are in a natural "frog" position during sleep, which is important for proper hip development. 
• Bottom zipper opening for easy nighttime diaper changes. 
• AloeKind breathable fabric: Placed in areas where the baby gets warm, it helps effectively release excess heat from the body, supporting natural temperature regulation. 
• Dual Tog: Suitable for year-round use, with a detachable zip 'n' pop lining that allows parents to easily adjust the warmth level with zippers and buttons without disturbing the baby's sleep.
• Ideal for home or travel: It is practical as you do not need to have multiple sleeping bags with different Tog units to adapt to seasons or changing temperatures.
