Theta Pouch
Theta Pouch

The Theta Pouch™ is the world’s first baby sleep sack made entirely from 100% organic bamboo; inside and out, redefining sustainability in infant sleepwear. Unlike conventional bamboo sleep sacks that rely on polyester filling, our GOTS-certified, plant-based design uses pure bamboo fill and is free from polyester, spandex, and elastane. Powered by SmartKnit™ Technology, it supports healthier, breathable sleep while significantly reducing synthetic fiber use; setting a new benchmark for responsible innovation that protects babies, empowers mothers, and honors our planet.

Evaluation comments:

“The fabric is so soft and cozy. The fabric feels cool to the touch, as if it keeps baby warm but does not overheat. Everything looks and feels very high quality. It can be used to swaddle bag or a sleep sack with the arms out, so it can grow with baby.”

“The sack has a nice quality zipper that closes at the edge, all around the sack, starting at baby’s legs. It has a cool mechanism to hold baby’s arms, with to pieces of fabric that are attached to the sack, and flam over one another. They stick together like it was Velcro, but it is not. I found this element very cool.”

“I feel the inner straps are very innovative, how they stick to each other without Velcro, and it’s very quiet in case you need to remove while baby is still sleeping. It also has a slight weight to it that I feel has helped my baby sleep better. It also can be opened from the bottom, to do middle of the night diaper changes.”

“I love the softness and the bit of weight it has. I feel baby felt nice and cuddle inside of the sack, which exactly what I want in a good sleep sack.”

“This sleep sack is incredible.”

“Super easy to use. Zipper easily glides open and closed.”

“I love that the chest band inside does not use Velcro! So many products for baby’s use Velcro which can be noisy and startle the baby. I love that this chest band is just grippy and is silent if you need to adjust it on baby.”

“I love how cozy it is for my baby. It gives a very comforting feel but is still breathable for all seasons.”

“I have already washed it many times and it washes up very nicely.”
