Using a 2.5 TOG Sleep Bag

Using a 2.5 TOG Sleep Bag

2.5 TOG sleep bag

As we are transitioning from summer to fall and winter, cooler temperatures may mean it’s time to change from summer sleep bags to winter sleep bags!

While 0.5 TOG is great for warm summer nights, you’ll likely need to transition to a 1.0 TOG or 2.5 TOG as it cools down.

If you’re unfamiliar with TOG and what that is, we have a blog for you to check out; but in short, TOG is a warmth rating for a garment-- basically how much heat it holds. In other words, the TOG rating is the ability of a fabric to keep your baby warm.

So a thicker TOG (like the 2.5 TOG) will hold in more heat, thus keeping your little one warmer during cold/winter weather.

A thinner TOG (like the 0.5 TOG) will hold in LESS heat, thus keeping your little one cooler during hot/summer weather.

what TOG for winter


A TOG rating is an easy way to determine what your baby should be sleeping in based on the ambient temperature in her nursery. It helps take the guesswork out of selecting your baby’s nightly pajamas. The higher the TOG rating, the warmer your baby will be.


Kyte BABY offers 3 different TOG ratings: 0.5 TOG, 1.0 TOG, and 2.5 TOG. 

 If you’re unsure when to use each rating, please refer to the blog about dressing baby for sleep and base it off the average nightly temperature of your baby’s nursery. You should keep in mind each baby has a different comfort level and these guidelines are only suggestions. Some babies may need a heavier TOG at warmer temperatures than others and some may not need the higher TOG rating until temperatures are much cooler.

The best way to check your baby’s warmth at night is by lightly touching his bare chest to gauge his temperature. Don’t judge based on feeling his feet or hands as they tend to be cooler than his actual body temperature. 

You can also keep a thermometer in the nursery so you have an accurate reading of the ambient room temperature and can dress them accordingly.

If you need to add layers under the sleep bag, that works too!


With the highest TOG rating that Kyte BABY offers, the 2.5 TOG Sleep Bag is made for keeping your baby cozy during the chilliest of parts of the year. Like those dead of winter nights! 

2.5 TOG Sleep Bags are recommended for use when the nursery temperature is 67ºF (20º C) or less. You can then adjust for cooler temperatures by using Rompers or Footies underneath the Sleep Bag for added warmth and comfort.

So how do you get the most out of the TOG you currently have? A few tips and considerations:

  • Try not to overdress them. Bamboo is meant to help regulate their temperature and their pajamas will add layers that add to the warmth rating of the sleep bag. If you want to keep the TOG rating low, make sure you dress in a onesie/body suit!
  • Ensure you’re checking the room temperature at different times of the day so you know when it may be warmer/cooler and can dress appropriately.
  • Closing the blinds/curtains can help keep the room at a consistent temperature throughout the day.
  • Try to keep your thermostat programmed to a consistent temperature in the home.

It’s normal to need to change the TOG of your sleep bag as the seasons change! When the transition to summer happens, an 0.5 TOG sleep bag will keep your little cool, comfortable, and prevents overheating!
