Sleeping Bag Size Chart and TOG Information

Most of our apparel is made from our signature Viscose from Bamboo, and we suggest washing them on cold/gentle cycle inside out. Lay flat to dry for optimal longevity or dry low and cool iron if needed. Follow all care tag instructions.

Viscose is know to be buttery soft and the softer the fabric, the more pilling is common — however, laying flat to dry really keeps the fabric new. Most moms prefer to line dry for optimal texture, lasting color, and to last through the life span of the item.

Due to the delicate nature of our lush fabrics, please do NOT wash with other items with zippers, buttons, or hardware. Snagging may occur. Wash separate with other babies items.

Our signature Päpook® viscose from bamboo is lightweight, breathable, and extra soft for your baby's delicate skin. Its natural weave makes it stretchy enough for a nice snug fit, yet comfortable for all-day wear.

No Harsh Chemicals
We comply with snug fitting standards to eliminate the use of flame retardant chemicals during our production process – irritants like chlorine-containing bleaches, zinc, and sulfate. So you can rest easy knowing our fabric is free of irritants and toxic treatments.

Benefits of Viscose from Bamboo
This fabric has it all. Lightweight and breathable with fibers to wick away moisture while micro-gaps aid in ventilation and heat regulation. 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 also has natural UV protection to protect your peanuts from sun rays in comfort.


At Posh Peanut, we do our bit towards fostering a more positive future, creating thoughtfully produced garments. Bamboo is one of the fastest-growing plants on earth. It requires very little water and grows 3-4 feet a day without any fertilizers. We are proud to say our products are made using the highest standards in textile.

So soft

Our child loved his 6-18 month one and we finally sized up. 23 months and he loves it. So soft and warm.

Zipper broke after 3 uses

I read another review about the zipper breaking but went ahead and purchased the item anyways. Within 3-5 uses the zipper broke in the middle of the night making it very difficult to get my child out of the sleep sack.

Buyer beware! Horrible product and experience

This was my third time trying posh peanut sleeping bag. The first was 2 years ago, when my daughter was an infant. i had no issues with that one, so I’m wondering if a quality issue happened in the almost 2 years since. The recent experience has been terrible. Within the first wash, I experienced loose threading/pulling on thread. This is a major risk of tourniquet syndrome occurring (when thread wraps around a toe or finger and cuts off blood circulation. Especially dangerous in the night when a parent can’t tell if it’s occurring). Customer service was great when I first reached out, offering a replacement product. I returned the damaged product and got a replacement. The same issue occurred again after only one wash (following washing directions directly and not even drying it). This time it took me 3 months to reach back out after the incident occurred —because life with a toddler—-and customer service initially told me they’d issue credit but now are telling me that there’s nothing they can do or offer because it’s beyond the 30 day window. Beyond frustrating and a major waste of money for a defective product.
