Dry Bag Upgraded 45L/40L/30L/20L multifunction waterproof dry sack for paddleboarding, kayaking and more
Product description
What it is and why you might want it
This Dry Bag Upgraded is a multifunction waterproof dry sack designed to keep your kit dry and reasonably organised when you’re on the water or out in wet weather. It’s aimed at people who do things like paddleboarding, kayaking or canoeing, but the use-cases go further: camping, fishing, rafting, swimming, and even general travel or storage at home.
On paper, the appeal is that it’s built around practical water-sport habits: you roll the top seal down, buckle it, and you’re trying to stop spray, rain and splashes getting into your belongings. The bag also includes some extra “on-the-go” touches (like a separate internal section for valuables and side carry options), which is the kind of thing that can save time when you’re packing and unpacking on the beach or at a campsite.
The essentials (and the main limitation)
The headline claim is straightforward: it’s described as a 100% waterproof dry bag, with the manufacturer emphasising protection for your equipment across conditions such as kayaking trips, whitewater rain, or being plunged into water. There’s also a useful nuance that’s worth taking seriously: the tip states that the outer layer zip cannot prevent immersion in water for a long time, but it’s “completely fine to just float on the water”.

So, if your plan involves sitting submerged for extended periods, you’ll want to treat this as a roll-top dry bag first and not a “fully safe in long immersion” bag. If your scenario is more like waves/spray, time on the water, and keeping essentials dry during loading and transit, then its approach makes a lot more sense.
Key features you’ll notice in use
What stands out is the mix of waterproof design and day-to-day ergonomics. The back of the bag is V-shaped and transparent, so you can locate items without fully unrolling everything. That’s a small detail, but when you’re wearing gloves or moving between paddle sessions, it can be genuinely handy.
There’s also an internal section intended for valuables, which helps if you’re trying to keep wallets/keys or other small items separate from bulk gear.
On the sides, there’s a new telescoping pocket and grip. The idea is that you can store water bottles and carry them by hand, rather than digging through your main dry section every time you need a drink.



And for the bigger sizes (40L/45L), the shoulder straps are widened to reduce pressure on your shoulders, with a detachable and adjustable length function. That’s a sensible response to a common issue with larger dry sacks: the bag might be waterproof and roomy, but it can still feel heavy once you’ve loaded it.
Tech specs (only what the listing actually gives)

Sizing and who it suits best
This is one of those products where choosing the right size matters quite a bit.

A 20L dry bag feels like the kind of size for smaller essentials: spare layers, a towel, a dry phone pouch (the listing recommends putting electronics in a waterproof bag for multiple protection), and maybe some simple fishing or swimming bits. If you’re packing light and want something that’s easier to carry, it’s likely the most “grab and go” option.
The larger 40L/45L sizes are where you start to feel the weight and bulk during portages or walks from car to water. The wider shoulder straps are directly aimed at that, so if you’re regularly carrying fully loaded kit over a bit of distance, it’s a factor worth weighing.
It’s not the best fit if you only need occasional protection for a couple of small items and don’t want to deal with a larger roll-top workflow.
How to use it properly (the sealing step matters)
The listing is clear about the sealing habit: for a better seal, roll the seal down firmly 3 to 4 times and fasten the buckle. That’s one of those instructions that seems obvious, but with dry bags it’s often the difference between “keeps things dry” and “why is my kit damp?”



A practical scenario: imagine you’ve just arrived at a paddle spot, you’ve got your phone and wallet, plus a change of clothes. You load the valuables into the internal valuables section, roll the top seal down 3 to 4 times, buckle it, then use the side grip/pocket for a water bottle. When you’re ready to move, you can keep essentials separate and avoid opening the main compartment unnecessarily.
Where it shines, and where it may fall short
Where it shines: - For keeping gear dry/clean/organised in typical water-sport and wet-weather trips. - If you value quick item access (thanks to the transparent, V-shaped back) and want an internal area for valuables. - If you’re carrying larger loads and want wider shoulder straps for 40L/45L. - For broader outdoor use beyond paddling: camping, fishing, travelling, and even home storage.
Where it may not be ideal: - The listing’s own tip about the outer-layer zip means you should not treat this like a long-immersion solution with the zip area relied upon. - If you’re trying to “max out” electronics safety, the text recommends extra protection by placing devices in a waterproof bag—so you may want to budget for that extra layer of protection.
Should you buy it?

It’s a solid pick if you want a roll-top dry bag for paddleboarding, kayaking or canoeing, and you’re happy to follow the sealing routine (roll 3 to 4 times and buckle). It also makes sense if you often carry heavier kit in the bigger sizes, because the wider shoulder straps are specifically called out for 40L/45L.
You may want to skip it if your use involves prolonged immersion where the outer zip area would be relied on, or if you only need minimal waterproofing and don’t want the workflow of rolling and buckling.
If your plan is more about keeping essentials dry during time on the water—spray, rain, splashes, and transport—this kind of dry sack approach is exactly what it’s built for.
