Shell is an ultra-versatile, multi-size backpack with a lightweight, weatherproof, yet minimalist design. Tropicfeel combined the ergonomics and benefits of a large hiking pack with the portability and minimalist design of a daily-use backpack. Shell is adjustable from 22L to 40L thanks to the compression side system of the backpack and the front webbing together with the kangaroo pocket. The compression-based wardrobe system allows you to pack up to 20% more than a typical backpack. It helps the user to feel at home when they are traveling: Just unpack, hang up the wardrobe, hang up your toiletries pouch, and experience a new level of organization.
