Why Modulith

Old backpack problems, solved once

Slouchy bags, fiddly zippers and buckles, capacity that never matches the occasion — everyday annoyances that deserve a better answer.

Slouchy & hard to organize

Ordinary soft bags have no structure. Load them up and they collapse, turning every search into a dig.

Fiddly to open and close

Endless zippers, buckles and straps mean grabbing one item takes several steps too many.

Capacity never fits the day

A big bag is overkill for the commute; a small one can't handle a trip. One bag rarely covers it all.

The system: base bag with two side modules
The System

3 independent bags, 1 seamless unit

Modulith is a base bag and two detachable side modules. Snap all three together into a single unit, or use each one on its own — configure it however the day demands.

The Base Bag

Built-in laptop compartment, storage shelf and configurable midsection. On its own, it covers your daily commute.

Side Modules — Two Sizes

A larger module for volume, a compact one for essentials. Each works independently as a crossbody or sling, and a built-in expansion layer more than doubles its capacity when opened.

Magnetic Attachment

No zippers or buckles to fight. Strong guided magnets snap modules on and off in one motion.

Core Features

Usefulness is a design decision

Four key design choices that turn "modular" from a gimmick into something you'll actually use every day.

01

H-Frame Construction

An internal structured frame keeps the bag's shape. Layered storage stays visible and upright — nothing collapses into a pile.

02

Modularity

Side modules carry a built-in expansion layer that more than doubles capacity, switching effortlessly between commute and travel.

03

Smooth Tactility

Forget fiddly zippers and clips. Strong magnets guide attachment and release in one satisfying motion.

04

Travel Compatible

Sized to pair with standard carry-on luggage handles — equally at home on a business trip or a weekend away.

Functional Details

Every touchpoint, considered

Fidlock fasteners, magnet piping, YKK zippers, a padded laptop sleeve — the small decisions that make the system feel effortless.

FAQ

Still have questions?

When will rewards ship?

The delivery timeline will be published on the Kickstarter campaign page at launch. Subscribers and backers get every schedule update by email first.

Can I buy a side module on its own?

Yes — side modules are available individually in both sizes, so you can expand an existing base whenever you need.

Are the materials durable and sustainable?

The design follows a "less is more" philosophy: durable materials and a system that adapts over time, so you replace less and waste less.

What's the return policy?

Pledges are managed on Kickstarter — cancel any time before your reward ships for a full refund, and return within 30 days of delivery. See the full Crowdfunding & Refund Policy for details.
