Choosing your child's first school backpack is about much more than design. Every child has a different body shape, height and individual needs. That's why BAAGL offers two backpacks designed specifically for first graders – AIRY and AIRY PLUS.

Both models were developed in cooperation with physiotherapist Mgr. Iva Bílková from FYZIOklinika to support healthy posture and comfortable everyday carrying. They are suitable for children from the first year of primary school. While they share many features, each model is designed for slightly different needs.
So, which one is the right choice for your child?
What do AIRY and AIRY PLUS have in common?
Whichever model you choose, you'll get a backpack designed with children's comfort, ergonomics and safety in mind.
Both models feature:
- ergonomic breathable back panel,
- fully adjustable shoulder straps,
- chest and hip belt for better weight distribution,
- intuitive Fidlock magnetic buckle,
- durable, high-quality materials,
- reflective elements for increased safety.
Both backpacks are suitable for children starting primary school and help support healthy posture from the very first day.
AIRY – An Ultra-Light Backpack for Smaller Children
The AIRY backpack is an excellent choice for children with a smaller or slimmer build.
Its biggest advantage is its ultra-lightweight construction, helping reduce unnecessary strain on a child's back. Combined with its ergonomic design, AIRY provides excellent comfort for everyday school use.
"AIRY is lighter and fits smaller children perfectly."
Mgr. Iva Bílková, FYZIOklinika
AIRY highlights
- ultra-lightweight construction,

If you are looking for a light backpack that won't weigh your child down, AIRY is an excellent choice.
AIRY PLUS – More Space and a Backpack That Grows with Your Child
The AIRY PLUS builds on the AIRY model while adding several practical features. It combines the benefits of a classic backpack with those of a traditional school satchel.
Its key feature is the Grow adjustable back system, which can be adjusted to four different height settings as your child grows. The backpack also includes a lightweight aluminium back support that helps maintain its ergonomic shape.
A reinforced base provides better stability, and inside children will also find integrated notebook folders that help protect school books from getting creased.
Another practical touch is the insulated lunch pocket, which helps keep snacks fresh for longer.
"AIRY PLUS offers a sturdier construction and more storage space. As a physiotherapist, I especially appreciate the lightweight aluminium support and the adjustable back system, which allows the backpack to grow together with the child."

Every Child Is Different
There is no single "best" school backpack. The right choice is the one that fits your child's body comfortably, sits correctly on the back and can be properly adjusted.
"Every child needs a slightly different type of backpack. The most important thing is that it fits the child's body, feels comfortable and can be properly adjusted using the adjustable straps."

Frequently Asked Questions (FAQ)
What is the difference between AIRY and AIRY PLUS?
The main difference lies in the construction. AIRY is ultra-lightweight and ideal for smaller children. AIRY PLUS offers a larger capacity, a sturdier construction and the Grow adjustable back system, which can be set to four different height settings as your child grows.
Is AIRY PLUS also suitable for smaller children?
Yes, but if your child is very petite or of smaller build, AIRY usually fits better. Every child is different, so we always recommend trying the backpack on and adjusting it properly.
Does AIRY PLUS have more space than AIRY?
Yes. AIRY PLUS offers a larger capacity and a more practical interior organisation. It suits children who need to carry more school supplies, or parents who prefer a roomier backpack.
What is the Grow adjustable back system?
Grow is an adjustable back system that lets you set the back height to four different settings as your child grows. This way the backpack fits well on the back for longer and adapts to your child's changing build.
Will AIRY PLUS last longer than AIRY?
Thanks to the Grow adjustable back system with its four height settings, AIRY PLUS adapts better as your child grows. That does not automatically make it the better choice for everyone, though. For smaller first graders, the lighter AIRY model may be more suitable. What matters most is that the backpack matches your child's current build and sits correctly on the back.
Which model is lighter?
AIRY is the lighter model, designed with the lowest possible weight in mind. That makes it an excellent choice especially for children with a smaller build.
Are both models ergonomic?
Yes. Both AIRY and AIRY PLUS were developed in cooperation with physiotherapist Mgr. Iva Bílková from FYZIOklinika. Both models have an ergonomically shaped back panel, adjustable shoulder straps, a chest and hip belt, and support proper weight distribution.
What school year are the backpacks suitable for?
Both models are designed for children from the first year of primary school. When choosing, we recommend taking your child's height, build and individual needs into account above all.
How do you adjust the AIRY or AIRY PLUS school backpack correctly?
Adjusting the backpack correctly is just as important as choosing it. The shoulder straps and the chest and hip belt should be set so that the backpack sits close to the back and the weight is evenly distributed.
With AIRY PLUS, you also need to set the Grow adjustable back system correctly. Only a properly adjusted backpack can make full use of its ergonomic features.
