When we were ready to transition my daughter from her swaddle to a sleep sack, I figured any sleep sack would do. It’s basically a piece of fabric with a zipper, seems simple enough. I did a quick search on Amazon, landing on a budget-friendly two-pack. The reviews were good enough, and I pressed “buy.”

A day later, the sleep sacks arrived, and their budget-friendly nature was obvious. The fabric felt stiff and wasn’t something I’d personally want to sleep in, but we gave them a try. I dressed my daughter in one for a nap and she woke up with a head full of sweat. The non-breathable fabric was not going to do. I quickly returned to my Amazon search, purchasing a variety of more expensive sleep sacks, tossing these original ones in the back of the pajama drawer for emergency use only.

And once the new sleep sacks arrived, it was obvious why they were more expensive. These luxe fabrics were ones I’d like to sleep in as well!

If you’re overwhelmed by the sheer volume of sleep sacks on the market, we’re here to help. And don’t worry, you don’t need to spend a fortune. The list below features some sleep sacks starting under $20.

 

 

Keep in mind that the material and warmth of sleek sacks can vary greatly. When shopping, look for the TOG value, which is a unit of measure of thermal insulation used in textiles. Consider the room temperature where your baby is sleeping. Recommended room temperature for babies is between 68-72 degrees Fahrenheit, but of course, that optimal temperature isn’t always possible.

Brands typically feature products rated .5 to 2.5 TOG. The higher the TOG, the warmer it will keep your baby (so in colder temperatures, you want a higher TOG). According to Kyte Baby, TOG ratings and the associated temperatures are 0.5 TOG for 74-78 degrees, 1.0 TOG for 69-73 degrees, and 2.5 TOG for 61-68 degrees. Many of the featured brands below offer similar sleep sacks with varying TOG ratings. If you fall in love with one brand or style, you can get it in different materials for different seasons.

These are our 12 favorite sleep sacks, perfect for all seasons, saving you from scrolling through pages and pages of Amazon options.
