RAINSMORE 40L Foldable Hiking Backpack (Water-Resistant) – Lightweight Rucksack for Walking, Camping & Travel

What it is and what it’s for

The RAINSMORE Hiking Backpack is a 40L foldable rucksack aimed at everyday outdoor use: short hikes, walking days, camping trips, and quick travel where you want a proper bag that can also pack away neatly. On paper, the appeal is the mix of size (40L), organised storage (multiple pockets plus a base shoe compartment), and practical “in the field” touches like a waterproof pocket for damp items and reflective tape for low-light visibility.

It’s the kind of backpack you’d choose when you don’t want a huge, heavy expedition load, but you still want enough room to keep things separated—especially if you’re the sort of person who prefers not to mix wet clothing with everything else.

Key takeaways for buying

The headline features aren’t just about capacity. The layout is clearly designed around common walking problems: where to put muddy shoes, how to keep damp items contained, and how to access smaller essentials without unpacking the whole bag.

A few things stand out: - A waterproof pocket meant for damp clothing or towels, to reduce the chance of moisture transferring to the rest of your kit. - A dedicated shoe compartment at the base, so you can swap into regular footwear after your hike without turning the main compartment into a mess. - Elastic straps on the front for quick carry of items like clothing layers, and for stowing trekking poles.

Is it perfect? Not necessarily. “Water resistant” and “foldable” are useful, but they’re also a reminder that this is geared toward practical day-to-day outdoor carry rather than being a rigid, ultra-technical pack for long, harsh conditions.

Where it shines in everyday use

If you’re heading out for a walk and you tend to bring the usual mix—jacket, spare layer, snacks, water, and a few small kit items—this backpack’s organisation should feel straightforward. The main compartment is positioned as your primary space for short trips, with slip pockets to keep smaller items easier to grab.

A small micro-scenario that makes sense with this design: say you finish a damp, muddy trail walk. You can keep wet trousers or a towel in the waterproof pocket, and you can move your shoes via the base compartment. Then you don’t have to dump everything into one wet heap just to get changed.

At night, the reflective tape on the front is a thoughtful touch. It’s not a substitute for proper visibility gear, but it helps your bag stand out in darker conditions.

Comfort and carry: what to expect

Comfort here is handled in the typical “walkers’ bag” way: adjustable breathable mesh shoulder straps are designed to reduce shoulder pressure, plus there’s an adjustable chest strap to help stabilise the load.

There’s also a chest strap carabiner with a whistle described as a lifesaving whistle carabiner. That’s the sort of feature that may feel slightly gimmicky until you actually think about the situations where a whistle could help. It won’t replace common sense safety planning, but it adds a practical layer.

One limitation to keep in mind: the listing focuses on comfort adjustments, not on advanced suspension systems. So if you’re planning long days with heavier loads, you may find you need to be more deliberate about packing weight than you would with more purpose-built trekking packs.

Tech specs you can use to judge fit (from the listing)

Tech specs

• Name: RAINSMORE Hiking Backpack 40L Foldable Lightweight Rucksack
• Type: Foldable hiking backpack
• Capacity: 40L
• Dimensions (fully extended): 32 × 23 × 53 cm
• Dimensions (folded): 24 × 24 cm
• Weight: 0.74kg
• Colour: Black and Blue

The weight is on the lighter side, and that matters if you’re carrying it for travel or you want something that won’t feel like a burden on shorter day walks. The folded size also helps if storage at home is limited.

Durability and weather resistance

The backpack uses tear-resistant waterproof material and mentions reinforced stress points plus premium SBS zips for long-term durability. That’s the set of details you want to look for on something that’ll be zipped and unzipped repeatedly.

On the weather side, it’s described as water resistant rather than fully waterproof. So it’s sensible to treat it as “rain and splash-friendly” for typical outdoor days, not something you’d rely on to protect everything inside during prolonged heavy downpours.

Also, the listing includes side and base adjustable straps for secure attachment of items such as tents, sleeping bags and other gear. That flexibility is useful if you’re packing more than just clothing and snacks, but it also means you’ll want to make sure straps are set properly before you set off.

Is it worth it?

It’s a good fit if you want a lightweight 40L foldable rucksack with organised storage for short outdoor trips and day-to-day travel, especially if you value features like a waterproof pocket for damp items and a dedicated shoe compartment.

You may want to skip it if you’re expecting a highly technical trekking pack experience (advanced suspension for heavy loads, or true fully waterproof performance in extreme conditions). It looks more like a practical outdoor organiser than a rugged expedition tool.

If you’re deciding between carrying an all-purpose bag versus something specifically designed for walking and camping, this sits firmly on the “for the outdoors, but still sensible” side.
