Yeah, the Sea to Summit Big River Dry Bag is known for being pretty durable.

It's a go-to for a lot of folks who need to keep their stuff dry in wet conditions, like kayaking or hiking through rain. From the manufacturer's description, it's got a waterhead rating of 10,000mm, so it's good for rain and splashes but isn't meant to be completely submerged.

Our research shows that it's really effective at keeping gear dry as long as it doesn't go under water.

So, for things like rafting or hiking in wet areas, it should do the trick. Just keep in mind it's not designed to be held underwater, so water might sneak in if you try.

As for holding up against wear and tear, people seem to like how tough this bag is. It's made with materials that resist scratches and damage.

When you roll and close it properly, it seals out water nicely, even in bad weather. That said, it's best not to test it by submerging it for long periods since that could push its limits.

So, if your adventures involve some water exposure but you're staying above the waves, the Sea to Summit Big River Dry Bag could be a good fit.

Just stick to the guidelines and avoid dunking it, and you should be all set.

If you're checking out the Sea to Summit Big River Dry Bag, knowing what sizes are available can definitely help you pick the right one for your adventures. From our research, this dry bag comes in quite a few sizes: 3L, 5L, 8L, 13L, 20L, 35L, and 65L.

So whether you need something small for your phone and keys or a much larger bag for a full set of gear, you're covered.

They're all made with the same durable and water-resistant TPU-laminated nylon fabric, according to the manufacturer's description, which should handle most outdoor situations involving rain or splashes. Just a heads up though—the bag isn't designed for full underwater use, like being fully submerged for a long time, so keep that in mind based on what you plan to do.

It should be perfect for activities like kayaking or hiking where you might encounter some rain but not deep water.

A lot of people mention how durable and practical the bag is—great for things like kayaking or rafting—although, they do note it's not the best if you're looking for something that can be submerged completely.

So if that's what you need, you might want to check out other options. Otherwise, this dry bag sounds like a solid choice for keeping your gear dry during all kinds of outdoor adventures.

So the Sea to Summit Big River Dry Bag—specifically the 8-liter one—is solid when it comes to dealing with rain, splashes, and most of the usual wet stuff you run into during activities like kayaking or hanging out on a boat deck.

It's got a 10,000mm waterhead rating, according to the manufacturer's description, which is pretty strong for keeping water out when it's not fully submerged. But keep in mind it's not made for going underwater completely.

From what we've found, this is more than just a manufacturer precaution. People who've used it often say it does a great job keeping things dry in rainy conditions or when attached to a kayak.

Its fabric is tough 420D nylon with a TPU coating, which can handle rough environments and keep things from soaking—as long as the bag itself isn't submerged. The seams are reinforced too, so a bit of rain isn't going to get inside.

However, if you decide to dunk it underwater, water might start to seep in eventually. Some folks have mentioned minor leaks when it was submerged, and that's backed up by professional reviews emphasizing it's not meant for diving into the water.

To get the best out of its water-resistance, make sure you roll the top tightly at least three times before clipping it shut. That's pretty important for keeping your stuff dry inside.

If you expect the bag to go underwater often, you might want to check out dry bags made for full submersion—they're out there if you need them.

In short, if you want something durable and reliable for keeping gear dry above water, the Sea to Summit Big River Dry Bag is a good pick. Just be aware of its limits with full submersion and think about what you need in a dry bag before choosing.
