Dry Bag Upgraded 45L/40L/30L/20L multifunction waterproof dry sack

What it is (and why you might want one)

This Dry Bag Upgraded is a multifunction waterproof dry sack made to keep your kit dry and organised when you’re on the water or dealing with wet conditions. It’s pitched at people who paddle (paddleboarding, kayaking, canoeing, rafting) but it also expects a wider life: camping, fishing, swimming, hiking, travel and even as storage at home.

On paper, the main selling point isn’t just the claim of waterproofing. It’s the practical design touches aimed at day-to-day use: a V-shaped back that makes items easier to spot, extra internal space for valuables, and side features for carrying and access. That mix matters because with dry bags, the “hard bit” is often not sealing the bag—it’s living with it while your hands are wet, you’re on a break, and you need your phone or water bottle quickly.

Key features that change how it feels in use

A few design elements stand out as “useful, not gimmicky”. The back of the waterproof bag is V-shaped and transparent, so you can find what you need without totally guessing. That sounds small, but if you’ve ever had to rummage through a fully sealed dry sack with limited time, you’ll understand the appeal.

There’s also an additional inner bag for valuables. Again, not a guarantee of protection by itself, but it gives you a more sensible way to separate “things that must stay dry” (like electronics or documents) from bulk items.

The sides add more practicality. The dry bag includes a telescoping pocket and grip on the left and right sides, which can be used for water bottles and to carry by hand. If you often end up with a bottle you want within reach, that’s the kind of detail that makes a dry bag feel less like a bag you only use once you’re already soaked.

For the larger sizes (40L/45L), the shoulder straps are widened to reduce pressure on your shoulders. This is aimed at heavier carry loads—exactly where dry bags can become uncomfortable.

Waterproofing: what’s strong, what’s worth understanding

The headline claim is 100% waterproof dry bag performance, with the important caveat mentioned in the description: the outer layer’s zipper cannot prevent immersion in water for a long time, but it’s fine to just float on water.

That distinction is worth taking seriously. If you’re planning for prolonged submersion, you may want to rethink expectations or plan extra protection for electronics. For shorter, realistic water scenarios—rain exposure, wet launches, splashes, and floating—this style of waterproof sack is often used as a “keep things dry enough” solution.

The suggested tip is also practical: to ensure a better seal, roll the seal down firmly 3 to 4 times and fasten the buckle. Dry bags live and die by sealing technique, so if you’re someone who doesn’t like fiddly steps, this might feel like a learning curve.

Capacity choices: 20L to 45L, but choose with your load in mind

You can pick among 20L, 30L, 40L and 45L versions. In general terms, smaller capacity suits lighter day trips—think swimming kit, a change of clothes, or basic fishing essentials—while the larger sizes are for bulk carry when you’re packing more than just the essentials.

But there’s a catch: larger doesn’t always mean easier. With any dry bag, big volume can tempt you to overpack, and if you end up with heavier items, comfort and access become more important. The widened shoulder straps on 40L/45L are helpful, yet you’ll still want to pack with weight distribution in mind.

Who it suits (and who may want to look elsewhere)

It’s a solid match if you want one waterproof bag that can handle both active outings (paddling, camping, rafting) and everyday storage. The transparent/V-shaped back and the internal valuables pocket suggest the brand expects you to use the bag beyond a single “emergency” role.

You may want to skip it if your priorities are very specific: if you need protection specifically during prolonged immersion, the description notes that the zipper on the outer layer cannot prevent long-duration immersion. Also, if you’re the type who hates rolling seals and fastening buckles every time you access the bag, you might find the system slows you down.

It’s also more in the “multifunction, outdoors-and-travel” lane than a specialist piece of gear designed for one extreme use case.

Getting the most out of it (practical tips)

Before your first proper outing, do a dry run. Practise rolling the seal down 3 to 4 times and fastening the buckle firmly—this is the step most likely to decide whether your kit stays properly protected.

When packing electronics, the description recommends placing the device in a waterproof bag for multiple protection. That’s a sensible approach because dry sacks mainly protect the bag interior, adding a secondary layer for phones or sensitive items reduces the risk from imperfect handling.

A micro example: say you’re paddleboarding and you want a bottle and phone accessible. You can use the side telescoping pocket/grip for your bottle, and keep your phone in the internal valuables area (ideally inside another waterproof sleeve if you have one). When you’re ready to move to a resting point, you’re not digging through everything to locate your essentials.

What to check before you buy

Since this is sold in multiple capacities, double-check which volume you’re selecting for your typical trip. If your usual load is closer to essentials, 20L/30L may make more sense. If you’re carrying heavier and bulkier kit, 40L/45L will likely feel more practical.

Also, consider your water conditions. The included guidance suggests it’s fine for floating and everyday wet exposure, but it’s not positioned as a long-duration immersion solution.

Final verdict

It’s worth considering if you want a multifunction waterproof dry sack with practical access features (V-shaped transparent back, inner valuables section, and side pocket/grip) and you’re happy to seal it the recommended way. It makes particular sense for paddleboarding/kayaking/canoeing days, and it can carry over to camping and storage at home.

You should probably avoid it if your use case involves long periods of immersion, or if you don’t want to rely on rolling the seal and fastening the buckle each time.
