Waterfly 25L Hiking Backpack Daypack with Rain Cover – lightweight rucksack for day hikes, travel and camping
Product description
The essentials
A daypack is only useful if it keeps your kit organised and comfortable once you’re a few miles in. The Waterfly 25L Hiking Backpack Daypack is built around a multi-pocket layout, with a carrying system meant for longer time on your shoulders and an included rain cover for wet-weather days.
On paper it sits in the “practical day hiking and short trips” bracket rather than heavy expedition territory. If your priority is stuffing everything for 1–2 days into one bag, grabbing snacks and essentials quickly, and not stressing about light rain, it’s the sort of rucksack you could genuinely live with.
That said, it’s worth tempering expectations: with a 25L capacity you’ll still need to pack with purpose, and “water resistant” doesn’t automatically mean it’s waterproof for deep, sustained downpours.
What makes it different (and where it helps)

The headline feature here is the multi-compartment design. The bag uses a main compartment plus two front pockets, two side pockets, two bottom pockets, and an anti-theft pocket. The anti-theft pocket is positioned as a place for valuables like an iPad, credit card, cash and a passport.
In everyday use, that kind of layout matters more than people expect. For example, on a short walk you can keep your phone or small items in a front pocket, water accessible via a side pocket, and then reserve the main compartment for your spare layer, snacks and any light rain gear. It’s also the sort of setup that helps when you’re moving between travel and outdoor time and don’t want everything mixed together.
If you like the idea of having “zones” for your kit, this design approach makes sense.
Comfort and carry system
Comfort is handled through an ergonomically designed carrying system. The shoulder straps are described as soft, and there’s a thickened back pad intended to provide support and distribute pressure. A chest buckle is also included to help keep the bag stable as you move.



The strap and back padding use elastic sponge elements, while the back panel is supported by breathable mesh. There’s also mention of a gap in the middle of the carrying system to encourage ventilation around the waist area.
Is it perfect? Not necessarily—comfort is always subjective, and without fit measurements or load guidance it’s difficult to guarantee how it’ll feel for every body shape. But for day trips where you’re wearing the pack for stretches rather than continuously, the features described are aimed at making that experience feel less tiring.
Materials, durability and cold-weather notes
The trekking backpack uses strong nylon-thread construction, with reinforcement at joints and the buckle made from cold-resistant materials. The brand claims it can withstand low temperatures down to -40℃ and still be usable normally.
This is a notable selling point if you often head outdoors in cooler conditions, or you simply want a pack that doesn’t feel fragile when the weather turns. One limitation to keep in mind: colder-than-usual conditions don’t automatically solve every durability concern, so it’s still sensible to treat it according to expected daypack use and avoid overloading.

Weather protection: rain cover included
An additional rain cover is included and intended to protect the rucksack from getting wet in heavy rain. That’s a practical detail, particularly for UK-style weather where plans can change quickly.
Still, it’s “for heavy rain” rather than a guarantee of full waterproof performance in every scenario. If you’re expecting persistent, driving downpour or you carry electronics that absolutely can’t get damp, you may want to use internal protection (like a dry bag or separate waterproof storage) alongside the cover.

Who it suits (and who should think twice)
It makes sense if you want a daypack for outdoor sports and short trips—especially if you like being able to separate items quickly. The listed scenes include travel, short hikes, camping, hiking, and cycling, alongside a wider set of activities. It’s also a good fit if you carry valuables and would rather have a dedicated anti-theft pocket for documents and smaller items.
It may not be a great match if you’re packing for longer trips where you need more volume or specialist compartmentalisation, or if you prefer a fully waterproof system where every seam and closure is designed to keep moisture out without relying on a rain cover.
Also, if you’re the type who needs a lot of gear for technical climbs or dense multi-day kit, 25L can feel tight—this is more day-first than “everything and the kitchen sink”.

Is it worth it?
The Waterfly 25L Hiking Backpack Daypack is worth considering if you’re shopping for a straightforward daypack with organised storage, a comfort-focused carry system, and an included rain cover for changeable weather. Its multi-pocket approach and anti-theft pocket for documents and valuables are the kind of practical details that can genuinely improve day-to-day usability.
You may want to skip it if you need guaranteed, all-conditions waterproof protection, or if you’re shopping for a larger, longer-trip pack where 25L simply won’t give you the packing room you want.
