Ultimate Guide to Cotton Versus Bamboo Sleep Sacks

by Bailey Bouwman

If like Avalon you're wondering if you should get a cotton sleep sack or a bamboo rayon sleep sack - we've got the answer for you. 

TL;DR - they are essentially the same. Choose the sleep sack you think is cute ;) 

Sleep bags, also known as sleep sacks, are a must-have for infants and toddlers. They provide a safe, cozy, and comfortable sleeping environment, all while giving your little one the mobility they need. But with so many options available, how do you choose?

PS - Check out our guide to picking out the perfect sleep sack for parents. 

Let's break it down understanding the different textiles available in the Nest Designs Sleep Sack collection.

Bamboo Rayon Sleep Bags

If you're after the silky softness that we all know to love, then bamboo rayon sleep bags might be your go-to.

They're smooth and cool to the touch, highly breathable, and exceptionally cozy to keep your little one snug all night. What's more, bamboo rayon boasts a bit more plushness and stretch, thanks to the Rayon Bamboo/ Cotton/ Spandex Blend.

However, it's essential to note that the chemical processing of bamboo rayon can be a bit messy. That's why we recommend Nest Designs bamboo rayon sleep bags. They're fully aware of this and make informed decisions when choosing bamboo materials, striving to find the best manufacturing methods.

But aside from the silky softness, and textile processing, it's all the same features you know and love. In Spring 2024, we're excited to offer Bamboo Rayon sleep bags in Nest Designs Spring 2024 Pantone collection with coordinating day rompers and adult sleepwear. 

Cotton Sleep Bags

Cotton sleep bags, particularly those made from 100% GOTS Certified organic cotton, are another excellent choice. We've shared the many amazing benefits of cotton sleep sacks previously, but they are definitely an understated under appreciated sleep product.

They may not have the silky stretch of bamboo rayon, but they're notably soft, luxurious, and will soften even more with each wash. Plus, they're gentle and non-irritating for the skin, making them ideal for babies with sensitive skin.

Although GOTS cotton isn't perfect, many parents prefer having that certification on their cotton products as it helps them make informed decisions on textiles.

Design and Features

They both feature:

  • Double zippers for easy accessibility
  • Zipper flaps for added comfort
  • Removable sleeves for ultimate comfort
  • Two sizes: 6-18months and 18-24months (same as Loulou 18-36months)

For those with newborns, consider the swaddle sleep bags in sizes 0-3 and 0-6, which feature removable swaddle wings. If you need bigger bags, consider their footed sleep suits.

TOG Rating

The TOG rating is a unit of thermal resistance used to measure the warmth of sleep sacks. Both our bamboo rayon and cotton sleep bags come with a 1 TOG rating, making them suitable for rooms with temperatures between 20-24 degrees Celsius. The removable sleeves also allow for adjustments to ensure ultimate comfort for your little one.

Making the Choice

Choosing between bamboo rayon and cotton ultimately comes down to personal preference. Some families might lean towards the silky stretch feeling of bamboo rayon, while others might prefer the soft and luxurious feel of organic cotton.

Or perhaps you're trying to decide between solids and prints. 

Remember, the most crucial part is that your little one sleeps safely and comfortably. We hope this guide helps you make the best choice for your family's needs - you can find both cotton and bamboo sleep sacks in our children's sleep sack collection with an assortment of styles and sizes changing each season.
