Convertible. Modular. Carryon Approved. 

The Drifter 4.0 Series of carryon travel backpacks is the culmination of 10 years of continuous improvement resulting from rigorous team testing & extensive customer feedback.

The 30L Drifter 4.0 is our original rugged weekender travel backpack strategically designed to maximize budget airlines’ smaller overhead compartment while also fitting below every airline seat*. 

The bag quickly converts from “backpack mode” to “duffle/carryon mode” with the roll top designed to cover up the shoulder straps, resulting in a more manageable experience when traveling with multiple bags, such as a personal item backpack (28L Ambassador 2.0 or 25L Drifter Mini 4.0) and/or checked suitcases/gear bags (surfboard, snowboard, golf, etc.).

The 30L Drifter 4.0 is our mid level convertible carryon backpack and comes included with 9 modular components:

4x economy compression straps, 2x padded handles, 1x duffle strap, 1x chest strap & 1x velcro divider

Maximize your carryon allowance and skip the checked luggage carousel with SOVRN Republic travel backpacks.
