CS Series

Since establishing the atelier in 2018, blooper backpacks has consistently produced backpacks through a custom-made approach.

In 2026, we introduce a new label: the CS Series.

Unlike custom orders, the CS Series is initiated by the maker.
Using existing models as a base, each piece is shaped by the maker’s accumulated experience and judgment, working with the materials available at that moment.

Every product presented here is made as a one-of-a-kind piece.

We hope it becomes a companion to the activity you believe in.
