MIYCOO Ultra Lightweight Packable Backpack (Waterproof, 35L, Foldable Daypack)
Product description
If you want a backpack that basically disappears until you need it, this MIYCOO packable daypack is built around that idea. It folds down into its own inner pocket for storage, then opens up quickly when you’re heading out for travel days, camping add-ons, or a hike where you don’t want something bulky.
Key takeaways
On paper, the big selling points are the ultra-light packable design, a waterproof fabric with IPX4 splash protection, and a practical 35L carry size split into 3 compartments. It also includes a wet compartment for separating damp and dry items—useful when you’ve got a rain layer, sweaty clothes, or water-adjacent gear.
That said, it’s not perfect for every scenario. IPX4 is about splashes and light rain protection, not deep submersion. And because it’s designed to pack small, it may not feel as structured as more rigid hiking packs if you’re planning long, heavy loads.
What it’s for (and what it’s not)
This is the kind of backpack you bring when you want flexibility. For travel, you can stash it in a suitcase, pocket, or day bag, then deploy it when you buy more items on the way or need extra room for a day out. For camping or hiking, it fits best as a daypack—think layers, water bottle, snacks, and a small set of essentials.
It might not suit you as a primary “all-day, every-condition” pack if you expect heavy weather, extended downpours, or rough treatment that demands maximum waterproofing and a heavily supportive frame. If your priority is maximum protection against rainwater intrusion or high-load comfort, you may want to look at backpacks designed specifically for those demands.
Where it shines in real use
The foldable design is the most noticeable part once you use it. You can store it compactly, then open it when you reach your destination—no big bag to carry around first. A quick micro-moment: on a travel day, you pack the folded backpack in your suitcase. Later, when you’re out walking and stop to grab groceries or souvenirs, you unfold the 35L daypack and suddenly you’ve got more organized space than a simple tote.
The compartment setup also helps day-to-day organization. Having a wet compartment means you’re not guessing where to stash something damp. It’s a small feature, but it changes how quickly you can pack and repack.
Also, the survival whistle on the shoulder strap is a nice detail for outdoor-minded shoppers—more “nice to have” than something you’ll use daily, but it’s there.

Durability and comfort considerations
The manufacturer emphasizes upgraded zippers and reinforced stress points, which is exactly what you want on a packable bag that still sees daily handling. Still, keep expectations realistic: packable backpacks often trade some rigidity for packability. So if you’re sensitive to how a backpack sits under heavier loads, it’s worth considering whether a more purpose-built hiking pack might feel better.
And remember the waterproof claim is IPX4. That’s good for splashes and light rain, but if you’re walking in steady rain for hours or dealing with puddles, you may still want additional rain protection (like a rain cover) depending on your trip.
Should you buy it?
A solid pick if you want an ultra-light packable daypack for travel, camping add-ons, and everyday hikes—especially when organization matters (dry vs. wet) and you like the idea of storing the backpack in a suitcase or pocket.
You may want to skip it if you need true heavy-rain waterproofing, a highly supportive carry for long, heavy hikes, or a more rigid backpack feel. It’s best viewed as a practical, portable 35L option designed for convenience and versatility, not as a top-tier expedition-style pack.
