[Waterproof] Sidekick 20 "Backpackable" Expansion Bag (Successor to the XS Base Pack model)

Take your extra gear with you, just as it is.

The Sidekick 20 is a 20-liter expansion bag compatible with Enduristan’s proprietary expansion system, ESI (Enduristan Standard Interface).

By adding 20 liters of storage, it is perfect for when your travel gear increases, such as camping equipment, extra layers, or food.

Increase your capacity only when you need it.

That is the charm of the Sidekick series.

Wear it as a backpack when you reach your destination

The greatest feature of the Sidekick 20 is that it can be used as a backpack.

By attaching the included 4-point harness, you can carry it as a daypack.

Moving through a ferry terminal.
Walking around a town.
Carrying gear to a campsite.
Use it just as it is after taking it off the bike.

This is a feature unique to the Sidekick 20 within the Sidekick series.

The capacity you need, right where you need it

Because it attaches quickly to ESI-compatible products, you can expand your storage to suit your travel style.

“I want to pack just a little bit more.”

In such moments, you can add 20 liters of storage space, while still being able to detach it and return to a lighter configuration when not needed.

Furthermore, it is equipped with additional ESI interfaces on both sides, allowing you to attach other expansion bags like the Sidekick 01.

Practicality in true Enduristan fashion

The transparent pocket allows you to see the contents at a glance, and the external drawcord provides quick storage for items like gloves or wet clothing.

Naturally, it features a completely waterproof, dustproof, and mudproof construction.

You can use it without worrying about rain or mud.
