Impressive innovation

Apparently I never realized that all other bamboo sleep sacks out there actually use polyester filling. But The Sleep Theory USA uses 100% organic bamboo filling instead!! No plastic fillers and they use sustainable and ethical practices. This is an impressive innovation!!!
Kristiana

Baby slept 5 hrs stretch for first time!

I heard about the Theta Pouch from our neighbor. She said all these great things about the sleep sack, I had to try it! My little girl loves it so much. She normally wakes up every two hours crying even when she is not hungry. The very first night we used the Theta Pouch, she slept five hours straight!
Harper

Company values are inspiring

The company’s mission and values are inspiring so we decided to give it a try. We are not looking back moving forward! The Theta Pouch is so premium, you can even tell by just looking at it. It is so buttery soft, it gets even softer after every wash.
Felicity

Where was this brand before?

After trying many sleep sacks, we finally settled with the Theta Pouch! Sooo buttery soft, you need to feel it to believe it! We have never seen a velcro this quiet. You can basically change or adjust the velcro without worrying about waking baby up. Game changer!!!
Sheena

You can tell right away that this is a premium product. The way the Theta Pouch feels extremely soft yet durable, I want one for myself!

This is my go-to sleep sack from now on!

OMG! This is my go-to sleep sack from now on! It's well made, we love the two ways zippers. It has an option to open widely from the bottom up so it's comfortable to change diapers at night without disrupting baby sleep. And of course the softness is out of this world!
Alejandra

We love everything about this sleep sack!

We love everything about this sleep sack! In addition to its features, what sold us the most is the company's values! The fact that they are able to help pay for life saving surgeries to underprivileged children and their sustainable practices hit right to my heart.

Make It Impossible To Protest Sleep

Babies often resist sleep due to unfamiliar environments, irregular routines, or the need for extra reassurance. The Theta Pouch provides that comforting embrace with its unique wrap and pouch design, mimicking the soothing sensation of a mother's hug. When babies wake and notice they are alone in their crib, the serene wrap helps them feel calm and secure, whether they prefer arms in (swaddled) or out.

Our sleep theory emphasizes that various factors contribute to a baby's ability to fall asleep easily and stay asleep longer; achieving restful sleep is like solving a puzzle, requiring all pieces to align perfectly.
