The 'Catamaran' Backpack by Haenska Opens and Closes Like an Envelope

Berlin-based design studio Haenska recently released a new version of its Catamaran backpack. These unique knapsacks are individually handcrafted and come in a variety of colors and style combinations.

Each Catamaran backpack is unisex, providing both a functional and minimalist solution to everyday storage. This collection does a tremendous job of blending industrialism and fashion into one unified piece. The bag is inspired by a traditional envelope and is opened and closed using a recognizable pointed flap. The bag even folds like an envelope when there are only a few things in it, as well as when it is not in use. The Catamaran backpack is also versatile, allowing for different ways to carry it. The bag can be used like a traditional knapsack, or transformed into a purse.
