All of the Swaddle Designs zzZipMe Sacks are designed in Seattle and one of the only baby sleeping bags made in the USA. Available in three sizes, they have a front double zipper, making dressing and diaper changes easier on you and baby. With the most modern designs on the market, you do not have to sacrifice comfort or durability with this sleep sack. Four fabric choices are available and the room temperature should be considered when making a selection. These bags are not recommended for temperatures under 65 degrees or over 78 degrees.
Material and Warmth
While this is an American company, they do use the TOG rating scale to help you make the best choice for your little one. The TOG scale is a European rating scale to measure the warmth of a product. Here are the four fabric options available for the zzZipMe sleep sacks along with their rating:
Cotton Sack – Cotton flannel fabric with a TOG rating of 0.7 (72 to 78 degrees), this is the lightest of the zzZipMe Sacks and should be chosen for warmer temperatures.
Baby Velvet Sack – 100% polyester velvet with a 1.5 TOG rating (68 to 72 degrees), best for normal room temperatures.
Cozy Sack – 100% polyester plush fabric, TOG rating of 2.2 (65 to 70 degrees), the Cozy Sack is the heaviest of the options and the most popular.
Organic Sack – Made from ecofleece: 80% certified organic cotton/20% recycled polyester. It has a TOG rating of 1.5 and is ultra soft. Best for normal room temperatures
The Swaddle Designs sleeping sack is available in three sizes: 3 to 6 months (up to 28 inches long), 6 to 12 months (up to 32 inches long), and 12 to 18 months (up to 35 inches in length). It is best to base your size decision on the babies length, not age. The body of the zzZipMe Sack is considered narrow compared to most, so you may need to go up a size if you have a slightly chubby baby.
Design and Features
The colors and prints of these sleep sacks are all considered modern or trendy. They are definitely stylish and not nursery cute, unlike many of its competitors. There are many vibrant solid colors available yet with a textured pattern to make them unique. This sleep bag is a little more narrow through the body (legs), whereas most others have a larger body and/or a bell shape, and some babies do not feel snug in them. Really you just have to base it on your own observations of babies preferred sleeping habits. The 2-way zipper design on the front is not found in most sleeping sacks, but helps with dressing and changing diapers without exposing the baby to cold air by unzipping the entire front. Machine washable with gentle detergent and drying on a low setting also make it easy to take care of.
What We Like
- Stylish prints

- Limited sizes available; 12-18 month size currently not available
Stylish, comfortable, and durable, the Swaddle Designs zzZipMe Sacks stand out in the mid price range baby sleeping bags. They are perfect for babies who are too big to swaddle, but who still like the security of being wrapped up. The two way zipper design is very helpful but strangely uncommon in other sleep sacks. With the different thicknesses and prints available, you are sure to find one that is right for you. We highly recommend any product by Swaddle Designs. They are in a similar price range as the Aden + Anias sleep bags but better in almost every sense.
