About Greco
What is 【GRECO / Greco】?
A 3D mesh cushion.
Simply put, it's a mesh cushion material used in bedding and other items.
It's a sustainable cushioning material developed in Japan, blended with sugarcane-derived resin.

We've adopted this GRECO cushioning material for the shoulder straps of three backpack models.
They are thicker than typical backpack shoulder straps.
The reason we chose GRECO for the backpack shoulder straps is that

when you wear the backpack, it disperses pressure on your shoulders, reducing the burden.
If you put a laptop, documents, files, PC gadgets, and drinks, it gets quite heavy.
With the thought of making it less tiring when carrying such heavy loads, we adopted GRECO cushioning for the backpack shoulder straps.
When I actually tried carrying two 2L PET bottles, I felt that my shoulders didn't hurt compared to my usual backpack.
It's recommended for those whose shoulders easily get tired from heavy daily loads.
