Overview

Description

The HALO SleepSack Ideal Temp Swaddle helps regulate baby’s temperature thanks to innovative material that absorbs, stores and releases heat. IntelliThread fibers are embedded within the cozy fabric and won’t wash out or fade.

The swaddle also features HALO’s signature three-way design that adjusts to fit baby’s sleep style: arms in, hands-to-face or one or both arms out. An inverted zipper (with scratch-free zipper covers) allows for easy diaper changes.

Another good-to-know: the design is recognized by the International Hip Dysplasia Institute as promoting healthy hip development.

“Back is Best” embroidery is a gentle reminder to place baby in this recommended sleep position.

Ideal Temp fabric is designed to be cozy with some stretch for comfort. Because of this, it can run slightly bigger than our other swaddles. Make sure to choose the correct size for your baby’s height and weight. We recommend sizing down if your baby is in between sizes

It should fit snuggly around your baby’s arms and chest. If you notice excess material, the swaddle may be too big. We recommend waiting until your baby is slightly older and bigger to ensure a snug fit.

Traditional swaddles were a nightmare
Traditional swaddles were a nightmare for us. Our little one kept wiggling her way out. The Halo swaddle was a game changer. Would definitely recommend.

Halo swaddles have been amazing
Halo swaddles have been amazing for our baby. The easiest swaddle we’ve come across with having tried multiple other brands. We plan to use Halo for future transitions to sleep sacks, etc.

Love the ideal temp products.
Love the ideal temp products. The Velcro is just VERY loud, there’s no easy/delicate way to remove the swaddle for a dream feed. Also not sure why there’s a large tag.

I adore this swaddle so
I adore this swaddle so much I am going to purchase the bigger size so we can keep using it. My LO was born at 11 pounds so the newborn size is already getting tight. I live in the Caribbean and I was worried it was going to be too warm since we don't use the air conditioner but it definitely does regulate temperature and keeps them comfortable.
