Compare the Curious George Sleep Bag in 1.0 TOG and 2.5 TOG. Learn which warmth level suits your baby's room temperature and season.
Quick answer
Choose the 1.0 TOG Curious George Sleep Bag for warmer rooms (around 24°C/75°F) and the 2.5 TOG for cooler rooms (around 20°C/68°F). The right TOG depends on your baby's room temperature and the season.
Why TOG matters for safe sleep
TOG (Thermal Overall Grade) measures the warmth of a sleep bag. Picking the right TOG helps your baby stay comfortable without overheating, which is a key part of safe sleep. The Curious George collection offers two TOG options, so you can match the bag to your nursery's temperature.
1.0 TOG vs 2.5 TOG: the main trade-off
The 1.0 TOG sleep bag is lighter and more breathable, making it a good choice for warmer months or heated rooms. The 2.5 TOG has a thicker fill, providing more insulation for cooler nights or air-conditioned spaces. The trade-off is that the 2.5 TOG may be too warm for hot summer nights, while the 1.0 TOG may not be enough for a chilly winter bedroom.
Checking room temperature is the key
The best way to decide is to check the temperature in your baby's room. If you're unsure, start with the lighter 1.0 TOG and add a layer of clothing if needed. Always feel your baby's neck or chest to check for overheating—if it's sweaty, remove a layer.
How to choose the right TOG
- Room temperature above 24°C (75°F): Choose the 1.0 TOG sleep bag. It's breathable and light enough to prevent overheating in warm conditions. Always check the room temperature before dressing your baby for sleep.
- Room temperature around 20°C (68°F): Choose the 2.5 TOG sleep bag. Its thicker fill provides the insulation needed for cooler rooms. If the room feels cold to you, it's likely cold enough for the 2.5 TOG.
- Transitional seasons or fluctuating temperatures: Consider having both TOGs on hand. Use the 1.0 TOG for warmer nights and the 2.5 TOG for cooler ones. Layering a onesie under the 1.0 TOG can extend its use into cooler weather.
