Best Waterproof Storage Cases of 2026

Compared with the Plano 3600, the Pelican 1170 gives up usable space and adds weight, but it brings a different kind of confidence. The interior is 10.54 by 6.04 by 3.16 inches, the shell is rated IP67 and crushproof, and the case weighs 890 grams. It is a compact vault, not a general-purpose box.

We choose it when the contents are fragile enough to need fitted foam and a stiff shell. The Pick-N-Pluck foam lets you shape a bed for a camera, a small drone, or a delicate instrument, and the automatic pressure valve helps the case equalize without pulling water past the O-ring. The double-throw latches feel deliberate: you can see and feel when both sides are seated. That combination is what separates it from a simple dry box.

The compromise is size. At 3.16 inches deep inside, the 1170 leaves little room for a tall item, and the outside measures 11.64 by 8.34 by 3.78 inches, so the 10.54-inch interior is shorter than the shell suggests. We still think it is the right pick for a small, expensive load that needs padding more than volume. The pressure valve is the quiet detail that makes it a travel case rather than a sealed box.

Foam is the reason to look at the Lykus HC-2510 before the plain dry boxes. The case comes with PU foam in the lid and base, and the interior with foam measures 8.66 by 6.69 by 3.62 inches. That is enough depth for a mirrorless camera, a microphone, or a small piece of test equipment, and the foam can be plucked to create compartments.

The rest of the case is built around that job. Lykus rates it IP67 through SGS, the shell is polypropylene, and the exterior is 10.83 by 9.45 by 4.25 inches. At 1 kilogram empty, it is not the lightest compact case here, but the weight comes with a rigid feel and a lid that closes with a solid press. The wrap handle and compact footprint make it easy to carry by hand.

We recommend it for gear that needs both a certified seal and real padding, especially when the case will ride in a vehicle or a boat locker. The interior is deeper than the outside suggests, which helps with a camera body or a small lens, but the case is still a compact unit rather than a full kit box. The foam is what makes the compact size useful rather than limiting.

Twenty-two inches is the outside of the Monoprice case; the inside is 20.1 by 10.9 by 6.8 inches. That gap matters, because this is a large case that still needs a tape measure before you order. The interior volume is listed at 1,497 cubic inches, and the case is rated IP67 for dust and water.

We like the amount of gear that fits inside for the footprint: a telescope tube, a pedalboard, several power tools, or a couple of drones can share the space with foam between them. The customizable foam comes in a block, so you carve out only what you need. The shell is impact-resistant and UV-resistant, which is useful if the case lives in a truck bed or on a deck.

The 11-pound empty weight is the first trade-off. Add tools or optics and it becomes a two-hand carry, even with the rubber handle. The case is not the one you toss in a backpack; it is the one you load once and leave in the vehicle until you reach the spot. That is a fair trade for the amount of protected volume.

We recommend it as the large-case value in this group, provided you measure the interior and plan for the weight. It gives you a sealed, foam-lined cavity at a price that is far below the premium large cases, and the foam is generous enough to protect fragile contents. The interior volume and the foam are the reasons it earns the space it takes up.

The Pelican 1010 is the case we reach for when the valuables are small enough to ride in a jacket pocket. Its interior is 4.37 by 2.87 by 1.68 inches, the shell is crushproof and dustproof, and Pelican rates it IP67 for water resistance. The included carabiner is not a gimmick at this size; it lets you clip the case to a pack strap or a belt loop instead of burying it in a bag.

We like it for a compact camera, a set of earbuds, spare batteries, a wallet, or a few small tools. The rubber liner creates the seal, and the automatic pressure valve keeps the lid from fighting you after a temperature change. The clear top also lets you check the contents without opening the lid, which is handy when your hands are wet. Those are the details that separate a Pelican from a generic plastic box.

The size is the whole point and the main limit. It will not swallow a camera with a zoom lens attached, and the 1.68-inch depth is better for flat items than tall ones. What it does fit, it protects well, and the clear/yellow body is easy to find in a dark bag. The carabiner is the detail that makes it a carry case rather than a box in a drawer.

A familiar full-size hard-case silhouette is the first thing the MEIJIA gets right. It measures 11.65 by 8.35 by 3.78 inches outside, close to the Pelican 1170's footprint, and it comes with customizable foam. The difference is the price: the MEIJIA sits well below the premium case without looking like a toy.

We recommend it as the budget full-size option for a camera, a drone, or a box of small tools that needs padding. The foam is thick enough to hold a compact camera away from the lid, and the empty case is rigid rather than flexible. The latches close tightly, and the shell has a solid feel that matches the case's job. We were also impressed by how much of the premium-case experience survives at this level.

The case is not as refined as the premium picks, but the parts that matter for protection are there: a molded shell, a full foam bed, and latches that close with a firm snap. It is a sensible way to get a full-size foam case without premium-case money. For a camera, a drone, or a tool kit that lives in a vehicle, the MEIJIA covers the essentials without asking you to pay for the badge.

At 1.75 inches deep, the Plano 3440 is a box for what rides in a pocket, not for a camera bag. The outside measures 7.38 by 4.5 inches, and the three cam-action latches pull a Dri-Loc O-ring tight. The lid closes with a firm press, not a zip or a screw-down seal, which makes it quick to open with wet hands. That shallow shape is the whole design: it slips into a jacket or a pack pocket and keeps a phone, wallet, and keys together.

We like it as a secondary case for kayaking, fishing, or a wet walk. It is wide enough for an older phone or a small wallet, and the latches are easy to work with cold hands. A phone, a wallet, and a set of keys leave enough room for a small multi-tool, but not much else. The box is not bulky enough to interfere with a paddle or a rod, which is the point of a slim dry box.

We recommend the 3440 when you want a dedicated valuables box that disappears into a pocket, and the larger Plano 3600 when you need one case for the whole trip. For a paddleboard or a small boat, that slim shape is easy to stow in a dry-bag pocket. The shallow footprint is the reason it comes along when a bigger box stays home.

At 0.78 pounds, the MOOCY 8-inch case is light enough to carry all day without noticing it. The exterior is 8.6 by 4.9 by 1.9 inches, the interior is 7.8 by 3.9 by 1.5 inches, and the body is a hard plastic shell with a gasket. It is a small case, but it is not a tiny trinket box: the interior has room for a compact camera, a flashlight, or a set of small tools.

The pluck foam is the useful part. You can pull out a custom shape for a fragile item, and the foam sits close enough to the lid to keep it from sliding. The built-in padlock holes are a nice extra for a case that might ride in a truck or a shared gear bin. We also like that the foam comes in layers, so you can adjust the depth rather than commit to one block.

The shell is sturdy for its weight, but it does not have the stiff, armored feel of the Pelican cases here. This is a light-duty box for a small load, not a case you stack under heavier gear. The foam and gasket are the right idea; the hardware is where the case feels less expensive. It is a fair choice for a flashlight, batteries, or a compact camera that needs light protection.

We recommend the MOOCY for a small tool kit or a pocket camera that needs a custom foam bed and a lockable lid. It is easy to carry and easy to stow, and the padlock holes add a little security. We rank it behind the more solid small cases here, but the low weight gives it a clear job. The padlock holes are a small touch, but they make it more useful in a shared truck or gear bin.
