Waterfly Crossbody Sling Shoulder Bag (Small Chest Bag) – Lightweight daypack for walking, hiking and everyday carry
Product description
The essentials
A small crossbody sling bag from Waterfly, designed for carrying your essentials without the bulk of a full daypack. On paper, it’s aimed at day-to-day errands and lighter outings like walking or biking, where you want easy access to your phone, wallet and keys rather than rummaging through a larger bag.
The standout idea here is the chest/bust-facing carry. That typically makes it simpler to keep important items within reach while you’re moving about. It also leans into an everyday “grab and go” feel: phone in the chest pocket, wallet and keys in the main area, and smaller items sorted using the extra pockets.
That said, it is still a small sling bag. If you’re the type who likes to bring a lot (extra layers, larger gadgets, bulky tech), this may feel limiting even though the layout is well thought out.
Key features
The bag’s size is listed as 37.5 x 20 x 9 cm and it’s described as weighing 250 grams, so it sits in the “lightweight carry” category. The main compartment is said to have 3 sections, plus a key hook—useful for keeping keys from being lost at the bottom.
There’s also a front pocket, and additional storage on the shoulder strap area, including a Velcro pocket. Combined, this multi-pocket approach is meant to help you stay organised without needing a separate organiser pouch.
For the chest pocket, the description calls out space for a mobile phone and an iPad sized device (it notes “less than 240 x 170 mm”). That’s a practical detail worth taking seriously if you carry an iPad rather than a smaller tablet.
What to know about comfort and carry
Comfort matters with sling bags, and Waterfly includes straps that extend to 100 cm, with 2 D-shaped buckles. The straps are also described as interchangeable between left and right, which can help if you prefer a particular side for wear.
The bag is described as having breathable, thick padding and adjustable straps to improve day-to-day comfort. It’s the kind of setup that can work nicely for short to medium walks—especially if you don’t want a heavy backpack pulling on your shoulders.
One limitation to keep in mind: adjustable comfort helps, but if you’re carrying heavier items, a small chest sling won’t behave like a proper hiking pack. It’s more “essentials on the move” than “load-bearing”.

Where it shines (and where it may fall short)
If you’re after a compact crossbody sling for daily life, this bag makes sense. The multi-compartment main pocket, key hook, and extra pockets on the front and strap are all practical features for keeping the usual items—phone, wallet, keys, and ID—separate and easy to reach.
It’s also framed as suitable for walking, dog walking, biking, hiking, travelling, and everyday use. For example, on a dog walk you can keep your phone and ID in the chest pocket, keys clipped on the hook, and smaller extras (like a card or small item) in the strap pocket—so you’re not digging around when you need something quickly.
Where it may not be the best match is if you expect lots of storage depth. Even with compartments, the overall size is clearly compact, and that can mean less room for bulkier items. It’s a sensible choice for essentials, but it can feel cramped for larger “day out” loads.
Is it worth it?
A solid pick if you want a lightweight crossbody sling that’s organised for everyday essentials, with a chest pocket designed for a phone and a tablet up to 240 x 170 mm, and a multi-pocket layout that helps reduce rummaging. It suits people who walk, cycle, or do casual hiking and prefer quick access over carrying a larger backpack.
You may want to skip it if you regularly carry bigger devices, need substantial space beyond wallet/keys/phone, or you’re looking for a more load-carrying hiking bag rather than a compact sling.
Worth checking before you buy: whether your iPad size (and any other items you carry) fits the stated pocket limits, and whether the strap length and left/right carry option works for how you like to wear it.
