I previously bought the small blue one and it's been super useful! Overall

I previously bought the small blue one and it's been super useful! Overall, I'm really happy with it. If I could suggest one small tweak, it would be adding some extra expansion/pleats to the internal zip pocket so it’s easier to grab stuff out of it. Other than that, it's fantastic!

Good customer service

I bought this bag in June 2026 and just started using it around July/August. It’s only September and the hook for the carabiners is already starting to wear down.

They replied to my email and sent me a brand new one. Andrea was very polite and responsive. Helped me solve the problem super fast.

Hey! I’m really sorry about this. It’s honestly frustrating to have something like this happen after barely using the bag. We’ve spoken, and I’m arranging you a replacement, so hopefully we can make this right. I’m just really sorry you had to deal with this in the first place. Thanks for being honest about it and for giving us the chance to sort it out!

After disassembling my current bucket bag

After disassembling my current bucket bag where I throw everything in without looking…your bag is organized and has a place for everything. It’s taken awhile to familiarize myself with the ‘stuff’ I need to trek throughout the day. It be camping, shopping or working, it’s a handy bag. I am receiving compliments, have referred many to you.

New favorite bag

New favorite bag. Love all the compartments and the materials are super durable! Love the fun rope colors. Rope not the most comfortable because of where the knot sits. Would love to see multicolored webbing options too!

The perfect bag for travelling

I bought this bag for a trip to Japan and it was the perfect bag. It fit everything securely without being heavy and made everything easily accessible. I went for the flat strap, which feels the most practical for me

Love this bag but strap tabs broke

Love this bag: the color, size, functionality and style. My mind is at ease now that everything (chapstick, phone, journal, snacks) have their place. However the black tabs that connect the bag to the carabiners ripped out less than 1 week of use. First one, than the other, which indicated faulty manufacturing. The team sent me a replacement however they recommended I select a different color just in case the batch was faulty. I have been wearing the green color now for a few days and sadly miss the beige. I wish I could have gotten the bag I wanted!

Hey, we know some time has passed, but we realized we never properly apologized here publicly, so we wanted to do that ❤️ I’m really sorry again about the tabs breaking. I’m glad we were able to sort it out with you privately over email and get a replacement sent your way. Hopefully you’ve been enjoying the new one and it’s been treating you much better! Thanks again for being so understanding and for giving us the chance to sort it out.

A very functional bag - probably best to choose flat strap if to use when hikinh

The bag in itself is a must, multiple pockets that allows tu organize items and make it easy to find back (sunscreen, ipods, keys etc). The inly weak point is the rope strap as the knot is not really tight and when hiking or biking, the rope will slide down and needs to be constantly readjusted. I suppose I will have to buy a flat strap…

Awesome!

It’s the bag I’ve been looking for a long time. I wanted something not too big to use on a daily basis and still big enough to hold everything I need (sketching on the go and still place to carry my purse). It’s exactly what I’ve been looking for!!!

I really love this bag! Size is perfect! Sturdy, cool look!

I really love this bag! The size is perfect to fit everything I need on a regular basis such as wallet, phone, waterbottle, pen, lipstick, medication etc. The bag looks cool and it feels really sturdy. Labmono already was on my mind for two years, but now I finally decided to buy myself an early Christmas present :) The size is perfect to wear on days out, cityhopping or spending a day outside with my camera. It's not cheap, but I'm sure it's gonna last a long, long time!

Review of the Labo Mono Sling Bag L

I’ve been using this bag daily and overall I’m very happy with it. I especially like the many well-thought-out compartments, and the main compartment that can be opened halfway – super practical for everyday use.

Whether I’m cycling, shopping, or even going out to a club, the sling bag has become a true all-rounder for me. The material feels durable and the bag is comfortable to wear.

One small drawback: the included carabiners with screw locks caused the attachment loops to fray a little. I replaced them with different carabiners, and since then I haven’t had any issues.

That being said, I’d definitely buy the bag again as it’s functional, stylish, and versatile.
