Differences Between Cotton, Bamboo, and Organic Baby Sleeping Bags

When it comes to what your baby wears to sleep, the fabric you choose matters.

As a parent, you want the very best for your baby - especially when it comes to sleep. You may be confused or overwhelmed with the countless options of fabrics available when choosing your baby’s sleepwear - cotton, bamboo, wool… we know that natural fibres are best for sleep, but which ones truly offer the safest and most comfortable experience for your baby? 

Bamboo is a popular fabric for infant sleepwear, but when it comes to sleep, organic cotton offers a safer, more natural and more durable option for your little one’s sleep. 

Let’s explore five reasons why organic cotton is the superior choice for baby sleepwear over bamboo.

1. Organic cotton is more gentle on baby’s delicate skin

Your baby’s skin is delicate, which is why the fabrics they sleep in should be as gentle and natural as possible. The National Eczema Association recommends choosing organic cotton whenever possible because it is grown without harmful chemicals, making it gentler on sensitive skin. Unlike bamboo, which requires chemical-heavy processing to soften its fibres, organic cotton remains soft from farm to product.

2. It’s more breathable than bamboo

Organic cotton is known for its exceptional temperature regulation. It is a naturally breathable fibre that allows baby’s skin to breathe, and in turn, regulates their body temperature and reduces the risk of overheating; all while keeping them warm and cozy for sleep. According to the Federal Trade Commission (FTC), bamboo that has been processed to make soft fabric no longer has the same qualities as bamboo. While it’s commonly marketed as moisture-wicking, its breathability is compromised due to the heavy processing it undergoes. Organic cotton maintains its natural breathability for a safer, more comfortable sleep.

3. Organic cotton is particularly durable 

We get it, babies grow out of things VERY quickly - so why invest in premium sleepwear? Our range of swaddles and sleeping bags are designed to last several years and multiple children - in part because they are made with organic cotton. 

Known for its strength and durability, organic cotton maintains its softness and shape, wash after wash. Unlike bamboo, it won’t pill, shrink or wear thin over time - offering long-lasting comfort to be (lovingly) passed down to younger siblings or kiddies amongst your friends and family.

4. Organic cotton is more sustainable than bamboo

Bamboo is commonly misconceived as a sustainable option. In reality, while bamboo can grow quickly, the processing it takes to turn them into a soft, wearable fibre is not as eco-friendly as some might assume - which requires harsh chemicals to break down the plant’s tough fibers. (goodonyou.eco)

Organic cotton is grown without pesticides and from non-GMO seeds, through eco-friendly farming practices that require fewer resources and without harmful chemicals. By keeping agricultural land free from pesticides, it also helps to maintain soil fertility for generations. When you choose organic cotton sleepwear, you’re not just protecting your baby - you’re making a healthier choice for the planet, its people, and future generations. (goodonyou.eco)

When shopping for organic cotton baby sleepwear, it's important to look for the GOTS (Global Organic Textile Standard) certification. GOTS ensures that the fabric is truly organic, free from harmful chemicals, and ethically made from farm to finished product. By choosing GOTS-certified organic cotton, you can trust that your baby’s sleepwear meets the highest standards for safety, sustainability, and quality - giving you peace of mind while your little one sleeps soundly.

5. It’s naturally warm for safer sleep

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 , we're excited to offer Bamboo Rayon sleep bags in Nest Designs Spring  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. 

Whether you're looking to improve efficiency, reduce costs, or stay ahead in the market, Custom Baby Sleeping Bags can offer significant value, and you can make better choices tailored to your specific needs.
