3 Standout Lightweight Montbell Pieces | A 28 g Wallet, a Camera Wrap and a Pouch, Honestly Reviewed

2026.02.06

Do you have gear you bought for hiking that somehow ended up in daily use? Montbell — the Japanese outdoor brand — makes a number of small, light, easily overlooked things that are dependable in town precisely because they were built to a mountain specification.

Cashless payment is the norm now, and in Japan the My Number national ID card is absorbing the driving licence too. As what we carry shrinks naturally, lightness stops being a specification and becomes something you feel every day. And with prices rising, more of us are looking for things that are genuinely good and last, rather than merely cheap — which is exactly where Montbell's mountain-tested small goods come into their own.

Here are three "grown-up lightening" items I've used hard and can no longer do without, in the mountains or in town. Compact companions that slip into daily life however you decide to use them.

Going light really means not having to think about what you carry

Say "lightening the load" and most people picture shaving grams. But what using these three actually taught me is that the real benefit of lightness is making fewer decisions.

Because they're thin and light, they can simply live in every bag. So the question of whether to bring them today never comes up. You forget things less, and you stop feeling like you're managing your possessions at all. Function-first gear in the Montbell mould lightens your head as well as your bag.

1. Flat Wallet: the right wallet for an era when your phone pays

First, the Flat Wallet (¥2,600 at time of filming).

What it is

It is very thin. It measures 9.2 × 10.8 cm and weighs 28 g. A bifold or a long wallet has thickness built into its structure even when nearly empty; here the cards and notes simply stack flat. There's a single coin compartment on one side, so it doesn't bulge even reasonably loaded. It takes up to six cards.

The material is ballistic nylon — the same shell fabric that balances strength against weight elsewhere in the range. There's a good spread of colours to choose from.

Actually using it

The leather wallet I'd been using weighed about 64 g with its contents. Leather is heavy in itself. The Flat Wallet, loaded, is light enough that I genuinely wonder whether I picked it up.

What I hadn't expected is how pleasant it is that the structure won't let you overfill it. Try to push more in and you know immediately that you've overdone it, so receipts don't accumulate and unused cards quietly drop out. Mine holds a credit card and my My Number card. Now that the card can carry driving licence details as well, it's got smaller still.

With most payments now electronic, the case for a substantial wallet has weakened. Your phone does the paying and the wallet is the backup — accept that and this thinness makes complete sense. It fits a flat pack pocket, a small shoulder bag, a jacket or trouser pocket without getting in the way, so the thought "small bag today, better leave it" never arises. Using the same wallet always means never leaving it behind.

One note: in the mountains, huts and rural transport still often want cash. As a wallet holding a minimum of notes, this thinness strikes the right balance.

Who it's for

• Anyone mostly cashless who wants a smaller, lighter wallet
• Anyone who wants one wallet for both mountains and town
• Anyone whose wallet fills up with receipts and cards

2. CLIMABARRIER Camera Wrap: wrap it, sit on it, protect it

Next is the CLIMABARRIER Camera Wrap M (¥2,000 at time of filming). "Camera" is in the name, but using it only for cameras would be a waste.

What it is

It looks like a square of cloth, roughly 50 × 50 cm, but there's a soft cushioning layer inside. That's Montbell's CLIMABARRIER: a windproof, breathable film sandwiched between fabric, which gives it warmth and a lot of stretch. So you can fold it or roll it without worrying about it. Because it has no fixed shape the way a case does, it doesn't care what you wrap in it.

It comes in black, blue and red, in three sizes: S, M and L.

Actually using it

Wrapping a camera or a lens is the obvious use, but wrapping a bottle of seasoning, something breakable, or an iPad — anything you'd rather not put loose into a pack — turns it into proper padding. When a dedicated case is overkill but bare isn't right either, this is what fills the gap.

The other big thing is that it's waterproof. Wet ground, snow, a cold bench: you can put it down without a second thought. In the mountains that's somewhere to set gear while changing a lens; in daily life it's a damp table, or a day you're wearing something you don't want marked. The moment you need to put something down, out it comes. Wrap, spread, wrap again — one cloth does the whole cycle.

Less a dedicated tool than a piece of reassurance you carry around with you.

Who it's for

• Anyone who wants to protect a camera or a device without a dedicated case
• Anyone who wants to set things down on wet ground without caring
• Anyone after a protective cloth that isn't tied to one purpose and takes up no room

3. U.L. MONO Pouch: it gives everything in your bag a home

Last is the U.L. MONO Pouch M (¥3,000 at time of filming). It's about as simple as it looks — a thin bag, nothing more. But since I started using it, my bag has stopped descending into chaos.

What it is

It weighs about 30 g and holds 1.4 litres. Empty, it's nearly as thin as a single piece of cloth, and it packs into the palm of your hand. The strap adjusts, and the section that sits on your shoulder is widened to spread the weight — long for everyday use, tight for hiking. There are plenty of colours.

Actually using it

Honestly, it doesn't look like it holds much, but the fabric is soft and swells to fit what's inside, so the feeling isn't "it won't fit" so much as "it settles in." Power bank, phone, earbuds, lip balm and eye drops, a drink, tissues, regular medication, the camera wrap from earlier, a mirror — all the small essentials go in.

Where it works hardest is inside a bag, as a bag-in-bag. There are no rigid dividers, and yet everything acquires a fixed place, and because it adds no thickness it doesn't fight the rest of your load. Stack things on top of it and the bag keeps its shape. Change bags and you move the pouch across as a unit, which means fewer things left behind.

In the mountains it's snacks, a headlamp, a camera, gloves; in town it's devices. The contents change but the pouch's job doesn't: gather things together so you don't have to search. That's all it is. And being thin and light is exactly what lets it live permanently in your bag.

Who it's for

• Anyone whose small items get lost in their bag
• Anyone using several bags who wants to move the contents in one go
• Anyone looking for a bag-in-bag that's light and doesn't assert itself

What I've settled on: quiet things you reach for most

These three aren't so much things you'd be stuck without as things whose presence you stopped noticing. Compact gear doesn't stand out, and yet it's often what gets used most.

Getting my wallet down to 28 g lightened my thinking too — an odd claim, but it's surprisingly easy to feel once you try it. Next time you sort out your bag, it might be worth asking of each thing: is this light enough that I could just leave it in there?

I hope one of these becomes another permanent resident in your bag.
