Naturehike Ultralight Foldable Waterproof Backpack (30D Nylon) Dry Bag for Hiking & Camping, 18L
Product description
The essentials
If you’re the kind of person who hates carrying a heavy pack “just in case”, this Naturehike ultralight foldable waterproof backpack is designed for that middle ground between day bag and proper dry storage. On paper, it gives you a compact form when folded, then opens up into a small backpack shape with an 18L capacity for hiking, camping and travel days.
The most practical appeal here is the combination of folding convenience and waterproof intent. It’s made from 30D nylon fabric with a waterproof zipper and waterproof adhesive tape to help keep rainwater out of the bag’s finer entry points. That won’t make it invincible in every storm scenario, but for typical outdoor showers and wet transport, it’s the right direction.
Key features that matter day to day

You don’t just get a “bag”, you get a layout that’s trying to make small items easier to manage. The description mentions bilateral gauze pockets for items like cups and tissue, plus an adjustable shoulder strap buckle, so you’re not stuck with one fixed fit. There’s also an included buggy bag (a carry/pack-away bag), which is one of those details you notice when you’re actually packing for a trip.
A big point in the design is the 30D nylon tarp material. The pitch is wear-resisting tear resistance and waterproof performance. In the real world, lightweight fabrics tend to trade some toughness for portability, so it suits lighter, careful use. It’s also quick-dry and handy—exactly what you want when weather changes mid-walk.
What stands out vs other ways to carry


This is aimed at people who want water-resistant organisation without committing to a rigid, bulky daypack. Compared with going fully “dry bag” style for everything, you get shoulder straps and a backpack feel. Compared with a basic lightweight rucksack, the waterproof zipper and taped approach are a key differentiator when you’re moving between wet conditions, car journeys, or damp campsites.

Worth noting though: the term “foldable waterproof backpack” can be a little misleading if you expect a fully sealed dry bag for submersion. The build is described as waterproof with tape and zipper—helpful, but it’s best thought of as rain protection and water resistance for everyday outdoor use rather than a guarantee for extreme water exposure.
Practical use examples
Imagine you’re hiking with a small lunch, a rain layer, and a water bottle. You arrive at a viewpoint and it starts sprinkling. With a waterproof zipper and adhesive tape, you can keep your main contents protected without fumbling with extra coverings. Then, once you’re done for the day, you fold it down to something described as “only the size of the palm” and pack it into the buggy bag—useful if you’re heading to another stop or flying and don’t want a bulky spare.
Another scenario: camping or outdoor travel where you need a compact organiser for wet-to-dry transitions. You can keep smaller essentials in the side mesh pockets and keep the core items in the main foldable compartment.

Who it’s for (and who should skip it)
It makes sense if you want an ultralight, packable waterproof backpack for hiking, camping and travel where storage space matters. It’s especially relevant if you’ll be carrying mostly lightweight gear and you’d rather have something that folds away neatly.


It may not suit you if you’re after a heavy-duty, daily workhorse rucksack that can take constant rough treatment. Lightweight 30D fabric tends to be more about portability than abrasion-proof durability, so if your use involves frequent bushwhacking, sharp edges, or you regularly overload the bag, you may find it a bit too “gadget-like” for the job.
The essentials: spec highlights to check

- Capacity: 18L
- Material: 30D Nylon fabric
- Weight: about 120g
- Waterproof approach: waterproof zipper and waterproof adhesive tape
If you’re choosing based on fit, take note of the mini adjustable shoulder strap buckle, because a little adjustment goes a long way when you’re relying on a compact bag that still needs to sit comfortably.
Mini FAQ
Is it actually waterproof?

The bag is described as waterproof, using a waterproof zipper and waterproof adhesive tape. That should help with rain exposure and keeping water out through fine spots, but it’s sensible to think of it as rain protection rather than guaranteed submersion performance.


How portable is it when folded?
The description says it folds down to a very small shape (described as roughly palm-sized) and is easy to fold, with a low weight that’s intended to be negligible in your overall carry.
What can you store inside?

It’s built around an 18L main compartment, plus side gauze pockets for smaller items such as cups, tissue and similar essentials.
Who is the strap designed for?
Because it includes a flexible adjustable shoulder strap buckle, it’s intended to let you set the strap length rather than forcing one size.
Is it worth it?
A solid buy if you’re looking for a compact, ultralight waterproof backpack/dry-bag style carry for hiking, camping and travel, and you mostly pack lighter essentials. It’s the kind of bag that earns its keep when you need rain protection but don’t want a bulky rucksack taking up space.
Better avoided if you’re after maximum ruggedness or you expect it to handle rough, high-abrasion use day after day. Also, if you need reliable performance under deep water exposure, this is better treated as water-resistant for everyday wet-weather scenarios rather than a specialist, fully sealed dry-bag solution.
