Learn how to pick the right TOG for your child's jersey sleep suit bag, with simple rules for room temperature, layering, and fit.
Quick Answer
For most rooms kept between 20-24°C (68-75°F), a 1.0 TOG kids jersey sleep suit bag is the safest, most comfortable choice. Match the TOG to your child's room temperature and layer underneath only when the room is cooler.
Why TOG Matters for Older Kids
As children grow out of cribs and into beds, they often kick off blankets or get tangled in them. A sleep suit bag replaces loose bedding with a wearable layer that stays put, but only if the TOG matches the room. TOG measures thermal insulation: the higher the number, the warmer the bag. A 1.0 TOG is a mid-weight option that works for most heated homes, but you still need to check the actual room temperature.
Room Temperature and Layering Trade-offs
A 1.0 TOG bag is not designed for very cold or very warm bedrooms. If the room drops below 20°C (68°F), you can add a layer of pajamas underneath, but avoid heavy blankets on top because they can overheat. If the room is above 24°C (75°F), a lighter 0.2 TOG option is safer. The trade-off: a 1.0 TOG gives you flexibility for most seasons, but you must adjust base layers as the weather changes.
Decision Rules for Choosing TOG
- Check the room temperature: Use a room thermometer to measure the actual temperature at your child's sleeping height. Do not guess based on the season. Place the thermometer away from heaters and windows for an accurate reading.
- Match TOG to temperature: For 20-24°C (68-75°F), choose a 1.0 TOG bag. For warmer rooms above 24°C, use a 0.2 TOG. For cooler rooms below 20°C, layer with pajamas or consider a higher TOG. Remember that a 1.0 TOG is not a one-size-fits-all for every season.
- Adjust base layers: In cooler rooms, add a long-sleeve cotton pajama set under the sleep suit bag. Avoid adding blankets on top, as they can be kicked off and create a suffocation hazard. Check your child's neck or chest to ensure they are warm but not sweaty.
- Check the fit: The sleep suit bag should be snug but not tight. Make sure there is enough room for your child to move their legs and roll over, but not so loose that they can slip down inside. For a growing child, a size 6-8 years bag offers room to grow while maintaining a safe fit.

Is a 1.0 TOG Sleep Suit Bag Right for Your Child?
Best for
- Children aged 6-8 years who have moved to a bed but still prefer the comfort of a sleep sack
- Families who keep their home between 20-24°C (68-75°F) and want a single mid-weight bag for most of the year
Not for
- Very warm rooms above 24°C (75°F) where a lighter 0.2 TOG would be safer
- Very cold rooms below 18°C (64°F) without additional layering, as a 1.0 TOG may not be warm enough
