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.

Softest PJs out there

These pajamas are our first Posh purchase. They are very soft and comfortable feeling, as well as stretchy. My 1 year old son fits perfectly in the 2T so I do recommend sizing up. We will definitely be adding more Posh Peanut items to his wardrobe. He loves the way they feel and reaches for them all the time!

Jax Pj’s

I love all their products...just wish there were more boy prints. Seriously the most comfy PJ sets and my son asks specifically for the “soft jammies”. Love all posh has to offer...boy moms are envious of the girls collections!!
