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.

Gamer sleeveless sleep bag 2.5 tog

Bought this for my new grandson who lives in Colorado. My son was thrilled with the theme in the idea of having a very warm garment for sleeping since no blankets are allowed in the crib. Although they have not used it yet, It looks a little long 0 to 6 months so it may be a little while before he gets to use it.

So sweet!!

I use a couple bamboo sleep sack brands but this is my favorite now! I swear they’re highest quality. The prints and the ruffles are so sweet!
