Choosing the weight of your grobag
A tog measurement is a European warmth rating: the higher the tog, the warmer the product. grobag® baby sleeping bags are available in three tog ratings.
Please note: A number of external factors determine the tog rating of the sleeping bag that should be used. These include the quantity of clothing the baby is wearing, the temperature of the infant’s bedroom, the baby’s health and the amount of bedding necessary to keep an individual infant warm – this may vary as it does for adults.
Check your baby regularly to ensure they do not overheat.
Your grobag® baby sleeping bag comes with a free nursery thermometer to help you select which tog baby sleeping bag to use and what sleepwear to put your baby in.

FAQ about warmth & tog rating:
Why only 2.5 togs when my Winter weight duvet is 12 togs?
Health professional guidelines recommend that Baby Sleep Bags should be ‘lightweight'. Our own research and our mounting body of "parent testimonials" confirm that our 2.5 Tog Grobag Baby Sleep Bags are ideal for the UK climate and for the recommended nursery nursery temperatures of 16°C to 20°C. A Baby Sleep Bag surrounds the baby, providing insulation from both below and above, and also a warm pocket of air around the baby.
Because of the low tog rating, Grobag Baby Sleep Bags also provide great versatility throughout the year, simply by adjusting the level of your baby’s nightwear. When the weather is very cold, simply add more clothing (this could include a sleepsuit, socks and even a cardigan). When the weather is warmer, or perhaps if your child is unwell, you can remove layers of clothing while still keeping your baby at the right temperature.
What does the TOG rating mean?
The Tog rating describes the warmth or "Thermal Resistance" of a product and is widely used in the UK to explain warmth levels of duvets.
Grobags are tog tested to conform to BS4745:1990 and to the new British Standard BS 8510:2009. Latest advice from Health professionals is that Baby Sleep Bags should be ‘lightweight' and to meet the new British Standard, Baby Sleep Bags must be between 2.0 and 3.5 togs for temperatures between 10°C and 20°C. This is why our main range of Grobags are 2.5 togs for the recommended ideal nursery temperature range of 16°C and 20°C.
Which weight of Grobag Baby Sleep Bag should I buy?
Our 2.5 tog grobags are ideal for Autumn, Winter and Spring and can be used right up until the Summer nights become warm. If your nursery is usually below 20°C, we recommend a 2.5 tog Grobag.
However, if you live in a particularly mild region or if you have well insulated and heated accommodation and your nursery is usually 21°C or above, you may prefer a 1.0 tog Grobag for year round use. Our 1.0 tog Grobags are ideal for use from during the Summer months when the nights are warmer and are also very useful in early Spring and Autumn for day-time naps whilst your baby is still in a 2.5 tog Grobag at night.
0.5 tog Grobag Baby Sleep Bags are for use in high Summer, for holidays abroad, or if your child is unwell and has a raised temperature. They are also useful for day sleeps year round, when your child is already dressed in clothing.
3.5 tog is for cold winter temperatures of 12 - 15'C.
