Fit & Measurement

The loose, comfortable fit gives your child plenty of room to move around, ensuring a peaceful night's sleep. Thanks to the length-adjustable buttons and foldable cuffs, this sleepwear truly grows with your child. Even if it seems a bit big at first, your child can wear it for a long time.

To find the perfect fit, just measure from your little one's shoulder down to the very end of the extended sock cuffs.

A little tip: Height, not age, is the best way to choose the right size.

Warm hugs, easy sleep

Happy sleepers, happy parents!

This sleep bag is designed for active little ones who are rolling, crawling, and taking their first steps. It allows them to move freely, supporting their development while ensuring a good night's sleep. A clear, functional design makes it perfect for toddlers who love to wiggle but aren't ready for blankets.

Features that make a difference

neck protection

Gentle material, easy everyday care

Seamless design with protected zipper: for ultimate comfort and safety. Soft, snug neck cuff: keeps baby's neck warm and comfortable.

This sleeping bag is made with unbleached cotton and OEKO-TEX® STANDARD 100-certified fabric. It is washable at 60°C for everyday convenience. Close zips and buttons before washing, and always follow the care label for complete instructions.

foldable socks

Foldable: play or sleep, cozy feet

Fold the socks over or extra warmth and snugness during bedtime. Unfold it for unrestricted movement and playtime. Perfect for active babies and toddlers.

The antislip dots keep the kids safe when doing bedtime routine.

easy diaper change

adjustable length

Grows with your baby: adjustable length for extended use

Designed for busy parents, our sleep bag's adjustable length system provides a simple and efficient way to adapt the size, ensuring a comfortable and safe fit for your growing child.

The foot warmers can also be folded up to make the sleeping bag shorter, adapting to the kids’s height.

size xl comes with zipper at the back for easy potty training

Size XL only

Size XL includes a practical, rear potty-training zipper for independent toilet access.

For toddlers, this design thoughtfully supports potty-training independence, allowing them to confidently manage bathroom breaks without waking up mom and dad.

removing the sleeves

Adjustable warmth for the bedroom

The sleeves have also a lighter filling than the main body. Detachable sleeves give you extra flexibility as the room temperature or your child’s warmth needs change.

TOG is a guide: always combine the sleeping bag with suitable nightwear and check that your child is comfortable.

When to use it

For bedtime, naps, and early mornings


This legged sleeping bag is made for children who do more than sleep before and after bedtime. Unfold the feet for brushing teeth, a bedtime story, or a toilet visit. Fold them over once your child is ready to sleep.

For children growing out of a standard sleeping bag


A legged sleeping bag is a practical next step for a child who wants more freedom to move than a traditional sleeping bag allows. It remains a wearable sleep layer while the separate legs support an active bedtime routine.

For everyday use and frequent washing


If a sleeping bag is used often, it also needs to be easy to care for. The 60°C washability makes this style practical for everyday use. Consider keeping a spare sleeping bag for times when one is being washed or dried.

Frequently Asked Questions

What is the difference between a legged sleeping bag and a regular sleeping bag?

A regular sleeping bag has one enclosed section for both legs. This style has separate legs, helping children crawl, stand, and walk more easily during the bedtime routine.

Which size should I choose?

Choose according to your child’s height:

M for 80–92 cm,

L for 92–104 cm,

XL for 104–116 cm.

Always check the neck and arm openings before use. The sleeping bag should not be so large that your child can slip down inside it.

What does 2.0–2.5 / 3.0-3.5 TOG mean?

TOG measures the warmth insulation of sleepwear.

2.0-2.5 TOG sleeping bag is designed for bedrooms of around 16–20°C.

3.0-3.5 TOG sleeping bag is designed for bedrooms below 17°C.

Consider the room temperature, clothing layers, and your child’s individual warmth needs.

* For the temperature ranges shown in the Thickness Table, the lower end of the range requires adding extra layers for warmth, while the higher end is suitable for wearing only a diaper.

My baby is easy to have skin problem, like eczema, what sleep suit should I choose?

For sensitive skin, PureGlow delivers. The sleep suit utilizes 100% premium undyed cotton for both the outer shell and the lining, guaranteeing soft, chemical-free contact with your child. Friendly to eczema skin. The garment is a vegan product.

Can my child walk in this sleeping bag?

Yes. Unfold the feet for easier walking. The anti-slip dots provide extra grip on dry, flat indoor floors. Always supervise young children while they are walking.

Can I wash the sleeping bag at 60°C?

Yes. This sleeping bag is washable at 60°C. Close zips and buttons before washing, and follow the care label for all care instructions.

What is the rear zip in size XL for?

Size XL includes a practical rear zip for children who are potty training. It helps them access the toilet more easily without taking off the entire sleeping bag.

How do I know whether my child is comfortably warm?

Check your child’s neck or chest. It should feel warm but not sweaty. Adjust the sleeves or base layer when needed, and consult the TOG guide if you are unsure.

What materials we use?

Main fabric: 100% undyed premium cotton

PureGlow sleeping bags are 100% OEKO-TEX certified, from all raw materials to accessories such as zippers and washinglabels. OEKO-TEX® STANDARD 100 is an internationally recognized label for textiles tested for harmful substances. It sets the benchmark for textile safety, from yarn to finished product.

What is baby sleep suit? What is the sleep suit for toddler?

A baby sleep suit, often called a wearable blanket or sleep walker, is a safe, blanket-style garment designed for infants and toddlers to wear during sleep.

Key Features and Purpose

  • Safety: It replaces loose blankets in the crib, eliminating the risk of suffocation or entanglement, which aligns with safe sleep guidelines.
  • Design: Unlike a traditional sleep sack (which is a bag), a sleep suit features separate legs (often footed or with ribbed cuffs). This allows toddlers to stand, walk safely, and move freely in their crib or when transitioning to a big-kid bed.
  • Function: It is crucial for temperature regulation. By choosing the appropriate TOG rating (thermal grade), parents can ensure the child stays consistently warm without overheating, leading to more secure and uninterrupted sleep.
