What is TOG?

TOG (Thermal Overall Grade) is the warmth rating used for baby sleepwear. It measures how well a fabric traps warm air to keep your baby at a comfortable temperature. The higher the TOG, the warmer the sleepwear, making it easier to choose the right SleepSack based on your room temperature.

Reviews

This is the only swaddle

"This is the only swaddle that has provided consistent night time sleep for my granddaughter. The design allows her to move her arms freely rather than being confined to one position which most other swaddles do not allow, all while keeping her comfortable. The material is great for the extreme summer temperatures."

— Sharise B. (5/5)

I really wanted to love

"I really wanted to love this because my older child used a number of Halo swaddles but the sleeves are impossibly narrow, even for a newborn. My child cannot open their arms, they stay clutched on his chest with this swaddle."

— Kameliya A. (1/5)

I like the fabric and

"I like the fabric and the idea of it but my baby would not sleep well when wearing it. It didn’t stop the Moro reflex so he was keep waking himself up. Maybe some babies are more likely be soothed by it but my baby is way to active when he sleeps."

— Alicja R. (2/5)

Love that it's stretchy, leaves

"Love that it's stretchy, leaves a lot of room for his little arms inside. I appreciate this kind of swaddle because it holds him relatively in place but doesn't suppress the startle reflex, which is important developmentally. Great quality material and dries well in the dryer, just takes a bit of time when you dry on low. Love the teal color, so pretty!"
