A feature-packed 35L dry bag for UK waters, but timing and price matter

Yes — if you’re after a well-rated, feature-packed dry bag with a phone case thrown in, the Premium 35L Waterproof Dry Bag Backpack is a solid buy. Still, at the current £39.99 price, it’s probably not the best time to hit “buy now.”

It’s sitting at 4.6/5 from 1,980 reviews. The price has dropped as low as £29.99 in the past, with a highest recorded price of £59.99, so right now it’s 33% under its £59.99 RRP.

First impressions: a practical 35L pack for wet British days

With 35 litres of space, this bag feels just right for a day on the water. You can fit spare layers, snacks, a towel, and the basics without ending up lugging a monster.

The black finish keeps it looking low-key. I find the backpack style handy for shuffling between the car park, slipway, or campsite, especially when everything’s soaked.

For UK weather, that practicality really counts. You’re often dealing with drizzle, muddy banks, and damp kit after a paddle on a lake, estuary, or the coast.

What do the key features actually mean on the water?

The main thing here is simple: it’s a waterproof dry bag meant to keep your gear safe during kayaking, canoeing, boating, fishing, rafting, swimming, camping, and even snowboarding. The brand points out its tough, tear-resistant build, which matters because, let’s be honest, dry bags get dragged over all sorts of rough ground before they ever see water.

The included IPX8 waterproof phone case is a genuinely useful extra. Amazon says it’s worth £8 and has ultra-clear windows, so you’re not just getting a bag — you’re also getting a decent way to keep your phone safe and usable.

That’s more versatile than a standard roll-top sack, especially if you want to check maps, tides, or make emergency calls.

Comfort gets a mention too. The adjustable, padded backpack straps should help with shoulder strain when you’ve loaded the bag up, which you’ll appreciate if you’re hiking from the car to the water or up a beach.

They do mention extra storage options, but honestly, the details are vague, so I’d count that as a small bonus rather than a game-changer.

How does it perform for paddling, fishing, and camping?

For casual or regular water use, 35L is a great all-round size. It’s big enough for day trips and short paddles, but not so huge it becomes a burden.

The tough but lightweight build suggests it’s made for everyday practicality, not ultra-light expeditions.

The real question isn’t whether it keeps things dry — that’s the whole point — but how easy it is to live with. Backpack-style dry bags are much easier to carry than basic cylinder sacks, which makes a difference in the UK where you often walk a bit from the car to the water.

The phone case really adds to the convenience, especially if you prefer one kit setup instead of juggling multiple pouches.

Is the build quality convincing?

The brand says it’s durable and tear-resistant, and they back that up with a 1-year quality commitment, including replacement or refund if something goes wrong.

That kind of warranty is reassuring, especially for a bag that’s likely to see rough use on wet decks and sandy beaches. Still, the listing sounds more promotional than technical, so I’d say the 4.6/5 rating from 1,980 reviews is the strongest evidence of quality here.

Is it good value for money?

At £39.99, the value’s alright, but it’s not a steal. It’s 6.0% above the average price of £37.74, and with a lowest recorded price of £29.99, you could do better if you’re patient.

The included phone case does make the overall package more appealing, especially if you’d otherwise buy one separately.

If you compare it to the Helly Hansen Rider Vest Buoyancy Aid at £41.49, the dry bag’s a bit cheaper, but they’re for different needs: the Helly Hansen is safety gear, this is for keeping stuff dry.

Against the AKASO EK7000 at £56.98, the dry bag is much more affordable and makes more sense if your main goal is dry kit, not recording video.

What should you watch out for?

Biggest heads-up: price timing. £39.99 is above the £37.74 average and a fair way off the £29.99 low, so it’s worth waiting if you can.

Also, take “waterproof” claims with the usual caution. You need to seal closures properly, and no dry bag is totally invincible if you submerge it for ages or overload it.

Bottom line for UK buyers

So, if you're after a 35L backpack-style dry bag right now, this one seems like a solid pick. Plenty of people like it, and those handy extras don’t hurt either.

Honestly, though, if you can hold off and snag it when the price dips closer to £29.99, you’ll get way more bang for your buck.
