The best sleep sack for babies in 2019

The Merino Kids Baby Sleep Bag for Babies offers exceptional temperature regulation in a well-made sleep sack that’s perfect for any season.

While I adore HALO sleep sacks, I absolutely love the Merino Kids Baby Sleep Bag for babies, too. My mother bought me one when she visited in the middle of winter. Otherwise, I may never have bought one because of the cost. Merino Kids sleep sacks run about $90 to $120, depending on the size, but the quality and long-term use of the sleep sack really does justify the cost.

With other sleep sacks, you’ll need to buy at least two for every season, but with Merino Kids, you only need one sack for the first two years. It’s an excellent value overall.

Wool regulates body temperature better than cotton or polyester. I never worried about either of my kiddos being too hot or too cold when they wore the Merino. And I’m one of those parents who is always concerned about their sleep comfort. When I slipped them into the Merino sleep sack, I knew they’d be safe and cozy. It’s also fire resistant and certified safe.

Not only does the Merino regulates body temperature, but it’s also exceptionally well-made. After almost three years of using the same sleep sack between two kiddos, it looks practically new. One reason for this is that you have to use specially formulated wool shampoo when you wash the sleep sack.

I used NikWax Wool Wash. You also have to line dry, otherwise, you can shrink the wool and remove the moisture-wicking ability of the sleep sack. But the odor-resistant qualities of wool, require you to wash it less. Your wool shampoo will last a long time.

The Merino sleep sack uses Australian merino wool and highly-loved by moms and dads. One verified purchaser on Amazon said, “This has been a great sleep sack. We got it for my son when he was a few months old, and he is almost 2 (so we are ordering the next size up).”

Another popular woolsack is the Woolino 4 Season Sleep Sack and it’s definitely a runner-up in this category.

Pros: Regulates temperature perfectly, high-quality, grows with your baby, only need one sleep sack, works for all seasons, super soft and cozy

Cons: Expensive, logo right on the front of the sleep sack, need a special wash
