The mmo backpack is made with the same size, design, and hardware,
with the only difference being the fabric.

You may have seen names like Slub, Wrinkle, Ripstop, or Cordura Eco in the product titles.
Each name comes directly from the fabric used for that version.

Since every fabric has its own characteristics,
each one creates a slightly different mood and feel.

With a variety of fabrics and three size options,
the mmo backpack offers a wide range of choices.
Being able to wear it differently depending on your style and situation
is what makes the mmo backpack so versatile.

We hope this guide helps with your decision.

Even though we tell ourselves, “It’s okay, the wear just adds character!”,

there are moments when your bag shows the traces of time.

No matter how fresh our first meeting was, there will come a time when a bag, worn and slightly messy from our daily adventures, needs a little cleaning.

While the best approach is not to wash it, if washing becomes unavoidable, hand washing is highly recommended. Here’s how to do it:

(But honestly… isn’t a slightly worn-in bag part of its charm? 🥹)

※ For bags, it’s best to clean only the dirty spots without fully washing.

This helps reduce wear and keeps your bag lasting longer.

Some stains or water marks on the fabric may not come out even after washing.

<Hand Washing 🧼>

① Remove the carabiner.
② For oily stains, lightly rub with a small amount of dish soap.
③ Wash gently with neutral detergent in water below 30°C (86°F).
→ Do not use fabric softener or a dryer!
④ Shake off excess water, blot with a towel, and lay flat to air dry.
→ Do not wring the bag!

<Machine Washing 🫧>

① Remove the carabiner.
② Loosen the front pocket string and turn the bag inside out.
→ Because there are plastic components on the exterior, always zip halfway and turn inside out.
③ Place the bag in a laundry mesh bag and wash with neutral detergent.
→ Use a gentle cycle.
→ Do not use fabric softener or a dryer!
④ After washing, shake off excess water and lay flat to air dry.

💬
At mmo, we rarely wash bags unless they get very dirty. Frequent washing can reduce the fabric’s water-repellent and water-resistant properties.

Above all… that slightly worn look is just part of its natural charm! 😏

Low-fit or standard-fit hats—or even ones you can pull down deep….

which style do you prefer?

At mmo, we offer lightweight low-fit hats and standard-fit hats that suit everyone,

regardless of age or gender.
(Low-fit hats are marked with LOW on the thumbnail for easy identification.)

Not sure which one would suit you just by looking at the product photos?
No worries—we’ve prepared some wearing shots for you. 😌

<Low-fit 🧢>

The low-fit hat features a slightly shallower depth, offering a light and comfortable wear.

<standard-fit 🧢>

The standard-fit hat provides a classic shape that fits anyone, regardless of head size or shape, for a natural, everyday look.

mmo bags are full of little hidden details.
Sometimes you don’t even notice them until later—only to think, “Wait, this was here all along?!”

So instead of finding out by chance later, let’s go over them now—so you can make the most of your bag from the start.

< How to Attach/Detach the Chest Belt & Use the Bottom Buckle >

The chest belt can slide up and down so you can adjust it to the most comfortable position. It’s also detachable.
And here’s a bonus: a small whistle is attached for use in emergencies.

At the bottom, you’ll find a keeper to hold the shoulder straps in place so they don’t dangle—it’s also removable.

On the underside of the bag, there’s a buckle designed to hold bulkier items like a picnic mat or camping chair, making it easy to carry more than just the essentials.

The Boston bag also features adjustable shoulder straps, a detachable cross strap so the whistle can be positioned for right- or left-shoulder carry,

adjustable handle lengths with a buckle system for securing bulky items on top, and a luggage strap!

While these details are similar to the backpack, they have their own unique differences.

Instead of a long explanation, a short video guide makes everything much easier to understand—so be sure to check out the video guide. 🤓

[Your order has been delivered.]

There’s nothing quite as exciting as a delivery notification on a regular weekday afternoon.

And now that the long-awaited item has finally arrived—
shall we unbox it together?

The first thing you’ll see when you open the delivery box is mmo’s quarterly magazine, filled with stories from the brand.

But it’s more than just something to read—it’s designed to be reused in many ways.
You can wrap flowers with it for a casually stylish touch, or use it as protective packing for cups and dishes when moving.

Give it a second life in your everyday routine.

Peek into the front pocket of your mmo backpack, and you’ll find a webbing strap.
Hook the carabiner onto it, tighten the drawstring, and just like that—the shape of your mmo backpack is complete.
(Just a note: attaching the carabiner directly to the string may cause damage.)

Now, let’s pack up the essentials before heading out.

A jacket, iPad, books, pencil case, water bottle, blanket…
Funny how there’s only one of you, but always so many things to bring along.

No worries, though.
With pockets tucked into every corner, your mmo bag brings peace of mind even to the heaviest packer.

mmo’s delivery box is designed without tape, so there’s no extra waste.
It’s neat, eco-friendly, and easy to recycle.

Alright then—time to sling on your new bag and head out!

Packable Clothing Guide

Did you know mmo products aren't just packable as bags—some of their clothing is packable too?

"Packable" means you can fold or roll an item to make it compact, so it's easy to carry or slip into your bag.

When folded, it takes up very little space, making it convenient for travel or outdoor activities.

mmo windbreakers and raincoats are perfect for this: pull them on when it rains or gets windy, and fold them down small to tuck into your bag when you don't need them.

So... how do you pack them?

Alright — I'll walk you through it step by step.

Other apparel items, such as the windbreaker or half raincoat, can be packed in the same way.

The mmo raincoat keeps you covered when the rain comes unexpectedly.

Just unfold it in a snap and head out light and ready.

Packable Bag Guide

Sometimes people ask why there’s no pouch with the bag.

The “pouch” shown on the product page is actually the bag packed down — this bag packs into itself, so no extra pouch is included.

Swipe-snap-stretch!  It’s easier than it looks — just follow along and see how quickly it packs.

Perfect for storage or tossing into your suitcase while traveling!

Not just the backpack — the crossbody and Boston bags can also be packed the same way.
