I honestly love this sling way more than I expected. There’s too much to explain in text, so I broke it all down in the video.

It’s quite light and I like how the magnets close. It can rip across the neck if your collar is too low, the adjusting is done through a loop that can get a bit big but it’s not so bad

Love the material and the look. I take this everywhere from work to the gym.

- bag exceeds quality in closing magnets and material

- the strap does slip and self adjust a bit

ES:01 ESSENTIAL SLING 1.2L

Good material and workmanship!

This bag has everything I want from a sling, with two minor issues: 1. I'd make the magnetic clasp a little more powerful, so that it has a more overbuilt and sturdy feeling 2. I don't like that the key ring is inside of the sealed compartment, so that I have to unzip the inside to grab keys. The loop plastic also feels a bit flimsy. Again, overbuilt would feel more reassuring.

Great shape and feel to the bag overall, just wish the smaller details matched the overall reliability of the materials.

ES:01 ESSENTIAL SLING 1.2L

Phone. Wallet. Keys. Done. Keeps me from overpacking, keeps me moving. No junk, no clunk

Tossed it in the rain, spilled coffee near it, carried it on the bike. no leaks, no fluff. H₂ORIZON fabric handles everything. Zippers and magnets still tight. It’s lean, functional, and feels built to last.

Snap the edges together and you’re done. No fiddle with zippers, no stuck sliders, no hitting your knuckles trying to open it. That MAGNASEAL works smooth every time.

No flashy logos, no noisy fabric. Just a clean, black sling that does the job quietly. I like that. Doesn’t broadcast “look at me”, just silently carries what I need.

Fits all I need.

Light as hell, small footprint yet handles rain, rough surfaces, daily commuting.

Rain, snow, sweat -> doesn’t matter. Sling stays dry inside.

I’ve been carrying the ES:01 daily. Wallet, phone, keys, AirPods — all fit easy. Feels solid, weatherproof and light. The magnetic seal snaps shut fast. No fuss, just works.

Nothing wasted on design. It doesn’t scream “gear bag”, but it handles my daily essentials without bulk. Fits under a jacket, stays tight

Strap buckle snaps tight, seams feel strong, material has real toughness. It’s clear they didn’t cut corners.

Let me start by saying: I like the bag. Nice materials, nice closure, nice buckle, and it's small and looks good.

The sizing listed is all over the place. On the site it says 1.2L, but on the bag it says 0.7L. What should be believed?

Also, it was a missed opportunity to make the interior zipper pocket just a tiny bit bigger to fit a passport with a sleeve; as-is, it will only fit the passport by itself (and just barely).

Also, it gets a bit awkward if you store your phone in the bag, as there's barely any room to store anything else. You pretty much have to choose between using the zipper pocket or front mesh pockets as you can't really use both unless you're only storing cash or tickets in one of them. For example, I can't realistically put my phone + airpods + card wallet in this bag without taking the airpods and phone out at the same time (because the airpods case wont fit in the mesh pockets if the phone is in there- it has to sit at the top or bottom of the phone).

I find myself still putting my phone into my pants pockets as a result.

I think there's further refinement to do with this bag, such as adding a tiny amount of additional material for expansion purposes. I think it can be done without making the bag appreciably bulkier. it really is a question of millimeters at this point. Still, I like this bag better than the "3L" bag because of the design and angle of the straps.

The opening and the design make it so that you can really only fit a wallet and keys in it. it is a very nice design and material though. It becomes quite expensive if you buy from Europe as you’ll be lopped with another 35 euros of duties on top of the price.

Its perfect if you do not carry a lot of things. I personally carry just my phone, airpods, keys and phone in there and thats pretty much all that fits.

このスリングが大好きです。とてもスタイリッシュで、すぐに取り出せます

Great materials and innovation. Would buy again.

ES:01 ESSENTIAL SLING 1.2L

Opening and closing this thing is a joy. cant go back to using zippers on my old slings.

Got mine launch week here in LA. I wanted something small and clean that didn’t scream ‘outdoor gear’ or ‘tech bro.’ This nails it. The strap buckle is fast, the pockets make sense, and the main compartment is just big enough for my essentials without tempting me to overpack. It’s light enough to wear all day but feels like it’ll last forever. Already replaced my old crossbody. Great if you dont need to pack a ton.
