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 25L Drifter Mini 4.0 is our all new day pack & the only model in our Drifter Series that is specifically designed to fit within budget airlines’ 18” tall "personal item" sizers, maximizing the below the seat allowance.

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 an overhead carryon bag (30L Drifter 4.0 or 35L Drifter HD 4.0) and/or checked suitcases/gear bags (surfboard, snowboard, golf, etc.). 

The 25L Drifter Mini 4.0 is our entry level convertible carryon backpack and comes included with 8 modular components:

4x basic compression straps, 2x padded handles, 1x duffle strap & 1x chest strap

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