According to the American Academy of Pediatrics, loose blankets are not safe in cribs for babies under one. And once your baby is a wiggly toddler, it’d be a rare occurrence for them to make it through the night without them kicking their blanket off! So what’s the best way to keep your little one snuggly and warm at night? Wearable blankets, otherwise known as sleep sacks.

First things first, let’s talk about warmth. Sleep sacks are measured by TOG. What is TOG, you ask? A TOG measurement is a European warmth rating: the higher the TOG, the warmer the product. The TOG value is a measurement of a blanket’s thermal effectiveness – aka how well it keeps your baby warm. Since we are focusing on sleep sacks that are good during the warm summer months, all the ones below have a TOG rating of 1.0 or lower.

A quick TOG guide:
1.0 Tog – Summer and daytime naps, warmer weather, and in rooms 68-75°F
0.5 Tog – Hot weather and very warm rooms 75-81°F

Now, onto our favorite sleep sacks for summer…


Eight Sleep Sacks for Summer | Thrifty Littles

Made from 100% Australian merino wool, the Woolino Baby Sleeping Bag will keep your baby “warm when it’s cold and cool when it’s hot.” It creates a micro-climate around your baby, maintaining a consistent and comfortable temperature – in warmer weather, it will absorb water away from your baby’s skin and release it into the atmosphere and during the cooler months it will trap and circulate warm air. Another thing to love about this sleep sack is the closable seat-belt slot that makes for easy transfer from the car (or stroller) to crib. This one is on the pricier end, but it may be worth the splurge as it can be used year-round and it will fit your baby from 2 months up to 2 years! BUY IT HERE.

Babies sleep better when they can feel your touch, but we can’t always be right there beside them while they sleep. Nested Bean helped solve that problem by creating a line of swaddles and sleep sacks that mimic your touch with lightly weighted pads on the chest and sides. Have a stomach sleeper? You can reverse the Zen Sack so the weight is on your baby’s back instead of their chest. The Zen Sack is made from 100% luxuriously soft cotton and has a TOG rating of 0.5. It has adjustable shoulder tabs that allow for growth and a two-way zipper system that makes middle-of-the-night diaper changes a breeze. BUY IT HERE.
