Convertible. Modular. Carryon Approved. 

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

The all new 25L Drifter Mini 4.0 

is the only model in our Drifter Series that is specifically designed to fit under the seats (and, more importantly, in the 18” sizers) of even the most budget of airlines, serving as the ultimate "personal item" allowance, freeing up another space for an additional overhead carry-on bag.

The bag quickly converts from “backpack mode” to “duffle/carryon mode” with the roll top designed to unroll and 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 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 removable basic compression straps, 2x removable padded handles, 1x removable messenger strap & 1x removable chest strap

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