Handy sling bag
After ordering one for a present I ordered one for myself, as described in the title it’s small but exactly what I was looking for. It will be ideal for when I go walking and to take in holiday, big enough to carry phone, money etc. lots of colours to choose from and looks well made.

Small
Material and quality really good. Loved the teal colour. My iphone14 wouldn’t fit in the back pocket (admittedly has a case on it) and main body felt full with 2 passports so unfortunately had to return. If they did the next size up in the same colour I would have no hesitation in buying that.

Very well made, good quality bag
I have very reluctantly bought a "man bag" - I bought it because following a serious injury I need to use crutches or a wheelchair for 1 - 2 years (hopefully no longer). Fumbling for my phone or wallet while on crutches was awkward and made me feel even more vulnerable than I already do in this condition. So I'm not a big fan of these things. I don't need quick access to hair gel, beard wax or any other male grooming stuff because I'd sooner have needles stuck in my eyes than use them. Oh and I don't have a beard. Having said that, this bag is excellent. It is very well made, spacious, comfortable to wear (either across my chest or back) and the "hidden pocket" is a great idea. I bought three different bags and this was by far the best. One was so small my hands wouldn't fit in the pockets. My hands are large, not XL. I can't vouch for whether it is waterproof as I've not been out in the rain. My wife told me it was a daft colour to buy because it would get mucky, so she scotchguarded it for me. It's holding up fine - better than I am. Maybe I need scotchguard? Anyway - I'm really pleased with it, would happily recommend it and might even keep using it once my vertebrae are fused.

The best bag to take on a trip to London
This bag is perfect for carrying your essential items, phone cards water keys power bank etc. Surprisingly there is lots of room in this little bad. It’s light it’s strong it’s comfortable to put over your arm. I would highly recommend this. Plus it’s secure as nobody can get into it from behind.

It's a good product just getting used to it
First time buy. Wanted something where I didn't have to bulk up my trousers or shorts pockets with wallet phone and keys and be hands free. This item delivers that. I like that it has a secure mechanism for anti theft and has several compartments. The wide strap too doesn't rub or irritate my shoulder/collar bone either. I prefer it to a money bag around my waist as that just gets in that way. It's just a bit bulky on my chest right now so maybe I need to use it more lightly not quite have everything in it

Secure and good size
Excellent buy, just what I was looking for. Secret pocket next to body for security and locking zip. Ideal for travel. Also a good size, can get phone, wallet, e-reader, sunglasses and a camera lens in it, no problem. Very comfortable with adjustable strap. Really pleased.

Good day bag but minor flaws
A decent bag for the price, the "lock" on the zips (effectively a mini carabiner) is a really handy feature and made me feel more secure keeping the bag on my back. It's a decent capacity for everyday items but don't expect to be able to fit any large devices or a water bottle. Being able to switch which side the strap goes is also great. The strap is unpadded but relatively comfortable. The main issue is the front pocket closes via a button that does not stay closed even with nothing or minimal items inside it, making it feel incredibly unsafe to leave anything in there (I have had items fly out).

Ich habe mir die WATERFLY Anti-Diebstahl Sling Bag speziell fürs Radfahren gekauft und bin absolut zufrieden! Lieferung und erster Eindruck Die Lieferung war extrem schnell, das Paket kam gut verpackt und ohne Schäden an. Die Tasche machte direkt einen hochwertigen Eindruck – das Material fühlt sich robust an, die Reißverschlüsse laufen sauber und die Verarbeitung ist top. Perfekte Größe und durchdachte Fächer Ich nutze die Tasche beim Radfahren, und sie bietet genau den richtigen Stauraum, ohne sperrig zu sein. Es passt alles rein, was ich unterwegs brauche: ✅ Schlüssel – sicher verstaut in einem separaten Fach ✅ Werkzeug & Pannenspray – für Notfälle immer griffbereit ✅ Kleine Trinkflasche – findet problemlos Platz ✅ Zusätzlicher Stauraum für Handy, Geldbörse oder Snacks Trotz des kompakten Designs wirkt die Tasche nicht überladen, da die Fächer gut organisiert sind. Tragekomfort & Sicherheit Der Sling Bag sitzt bequem, verrutscht nicht und lässt sich dank des ergonomischen Designs auch über längere Strecken angenehm tragen. Der Anti-Diebstahl-Verschluss gibt ein sicheres Gefühl, da man nicht direkt an den Inhalt herankommt, wenn man die Tasche auf dem Rücken trägt. Fazit Die WATERFLY Anti-Diebstahl Sling Bag ist die perfekte Tasche für Radfahrer, die eine kompakte, gut organisierte und sichere Lösung suchen. Sie bietet genug Platz für das Wesentliche, trägt sich angenehm und sieht dabei noch stylisch aus.

Very happy with the product. Excellent quality. Size is quite small. But a closer look revealed pockets placed strategically just sufficient to carry your bare essentials. On second thoughts, the size is perfect. It will hold your documents (passport, ticket etc), a book, a small bottle of water and one or two small items. It stays snug against your chest and has an anti theft lock. I would strongly recommend this bag.
