Technical information

Are you feeling restrained or bold? Why is the pocket reversible?

This backpack features a timeless design with a classic shape and structure. We added a removable, reversible pocket on the front so you can change up your style: restrained or bold? It's up to you! Many people often change bags because they get bored with the style - but you don't have to worry about that with this bag.

Comfort in use

Because you need a comfortable backpack when walking or cycling, we designed the straps with a curve to better fit all body shapes and sizes. We also added a chest strap to keep the bag stable on your back, which is super practical when you're on a bike.

Why the Academic line of bags?

Since we can't always wear our sports clothes when travelling to the gym, we created a line of Academic bags to meet the needs of demanding players looking for a high quality bag to carry their belongings in. We also created this line to provide a needed solution that would work well in humid or dirty dressing rooms, made of material that doesn't quickly absorb water and that can be cleaned more easily.


We all have the same problem when packing our sports bag: how do you keep your dirty shoes separate from the rest of your things? The ACADEMIC sports bag features a shoe compartment to conveniently separate your shoes from the main compartment. On the inside, there is a separator for your laptop. The bag also includes side pockets so you can store your water bottle while keeping it close to hand.

ACADEMIC 25L backpack compartments

The bag allows you to keep your sports gear separate from the rest of your things. It features 7 handy pockets, including a main compartment for clothes, a shoe pocket, two pockets for water bottles, one document or laptop compartment, one pocket for valuables like a telephone, and a catch-all pocket for small items.

Carry-on luggage.

This bag complies with the IATA standards and can be used as a carry-on bag when travelling by plane. We nevertheless recommend checking with your airline regarding their current size and weight restrictions.

Dimensions and weight.

Bag dimensions: 46 x 32 x 20 cm.
This bag weighs 748 g.

Eco-friendly design: two-colour dyeing

Dyeing textiles uses a lot of water, and also produces a lot of waste water from the dye baths. To reduce our environmental impact, we only dye every second thread, thus reducing our water consumption and our impact on the water supply. The interior of this bag is made from two-tone fabric (one dyed and one undyed thread), which reduces our CO2 footprint by 11%.
