baby on bed in sleep sack

As a parent, you want your baby to be as comfy as possible, especially while sleeping. After all, a comfy baby typically sleeps better! When you’re looking at the different sleepwear and blanket options on the market, you may have noticed the word “TOG.” Knowing what this word means and how to choose the best TOG rating for your little one can help keep them comfy, cozy, and sleeping longer.

what is a TOG rating?

TOG stands for thermal overall grade. It’s a standard of measurement in the textile industry to indicate how warm a garment is. It can be applied to everything from baby blankets to duvets and comforters. Essentially, a TOG rating lets you know how warm something will keep the person using it.

For babies, you’ll typically find sleep garments ranging from a rating of 0.5 to 3.5

what is the right TOG rate for my baby?

TOG rating and temperature go hand-in-hand. Determining the right TOG sleep sack for your baby depends on the outside weather and how that impacts the temperature inside, specifically in the room the baby is sleeping in.

Here is a TOG chart to give you an idea of where to start:

Choosing a sleeping baby for baby using the TOG chart

The TOG rating system might seem like a difficult concept to grasp--but utilizing it could be the best knowledge you give yourself for a happy night’s sleep and a new (and highly effective) bedtime ritual. A product that lives on the TOG rating system--as all of our aden + anais sleeping bags do--will earn you a peaceful night’s rest for the whole family. So, first thing’s first: let’s talk TOG.

What is TOG rating?

TOG, or “Thermal Overall Grade,” is a standardized unit of measurement that calculates the thermal insulation, or warmth, of a textile. A TOG rate is another way of determining the weight of a garment. And when it comes to sleeping bags, we use TOG ratings and temperature to classify whether our sleep sacks are appropriate for certain, specific seasons. A TOG sleep sack that is best for winter will have a higher TOG rating, while a lighter TOG sleeping bag will have a lower TOG rating. Learning the TOG rating system will be the fastest way to determine what TOG sleeping bag is best for baby.

The entire TOG rating system is based on the ambient temperature of a room. If you’re wondering where exactly to start, figure out the ambient temperature of your baby’s bedroom. Ambient room temperature refers to the temperature in a room and can be influenced by many factors--like the weather outside, insulation, use of heating and cooling systems, and humidity.

Why Choosing A Sleeping Bag For Your Baby Can Be Hard

As much as you wish you could make time stand still, your little one is growing at the speed of light. You’re ready to make the move to a sleeping bag, but how do you choose the right one? 

 

Think of TOG as a cheat sheet to figuring out the ambient temperature of your baby’s bedroom. Ambient room temperature refers to the temperature in a room and can be influenced by many factors including the weather outside, insulation, use of heating and cooling systems, and humidity.
