Why Bamboo?

Bamboo from viscose is lightweight, breathable, and extra buttery soft for your baby's delicate skin. Its lush texture makes it a favorite amongst all ages. Its natural weave makes it stretchy enough for a nice snug fit, yet comfortable for all-day wear. The natural fibers make you feel like it's your second skin.

No Chemicals?

Did you know most children's wear is treated with flame retardants? You can rest easy knowing our bamboo is not treated with chlorine-containing bleaches, zinc, and sulfate. We comply with snug fitting standards to ensure we don't use any chemicals during our production process.

Benefits of Bamboo From Viscose

It is hypoallergenic, allowing moisture to evaporate and dry quickly. In addition to being naturally hypoallergenic and anti-fungal, it is also odor resistant and naturally regulates body heat. Micro-gaps aid in ventilation by trapping in cool air during hot seasons and traps warm air during cold seasons. This means you stay cooler during the summer and a few degrees warmer during the winter. This makes it great specifically for people with sensitive skin and/or allergies.

It has natural UV protection to protect your peanuts from sun rays in comfort.


There are many ways to produce bamboo. Here at Posh Peanut, we are dedicated to giving back to our planet. Eco-friendly- bamboo is one of the fastest-growing plants on earth. It requires very little water and grows 3-4ft a day without any fertilizers. Since our bamboo is made without any harsh chemicals, we are proud to say our products are made ethically using the highest standards in textile.

Love the print and quality

This is the first posh peanut sleep bag that we’ve tried and we absolutely love it. It’s incredibly soft and the print is gorgeous. My 2 month old hates being swaddled so we tried the sleep bag and she is sleeping so much better.

Love Love Love Posh Sleep Bags

We have been using these sleep bags since my daughter moved to her crib around 3.5m. We absolutely love them! They are so soft and keep her at the perfect temperature so she sleeps all night!

Daughter sleeps better with it

Nice weight. Not too light, not too heavy. My 6 month old can pull herself to stand in the crib and is able to do so wearing this sleep bag. It’s beautiful and vibrant. Nice amount of stretch makes it easy to put on even after she’s already fallen asleep.
