11. Tropicfeel SHELL Backpack: Best Expandable Carry-On Backpack
Every now and then a new travel backpack catches my eye simply for its unique and innovative design. The Tropicfeel SHELL Backpack is definitely that bag.
The innovative 3-in-1 adaptable design converts the bag into three different sizes: 22L (Daily), 30L (Weekend), and 40L (Adventure). If you’re looking for one simple bag that does it all, you’ll appreciate this one. The Tropicfeel team wanted to combine the ergonomics of a large hiking pack with the portability and lightness of an everyday backpack. I’d say they succeeded.

The bag also has a clamshell opening that folds open like a suitcase, and inside you’ll find its unique inbuilt wardrobe system. You can store your belongings in different compartments of the wardrobe system, and then simply hang the bag in your hotel closet or on your bed. Voila, everything is within easy reach.
And other than all those fun highlights, you’ll find that the Tropicfeel SHELL Backpack still has all the features that come standard with a great pack, including weatherproof material, an adjustable sternum strap, a hip belt, and a straps holder to help tuck away stray straps.
