Altura Vortex 25 Waterproof Backpack



Very waterproof backpack that's big enough for a fully packed commute

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

If you want your bag to be properly waterproof then a roll-top is the way to go, and the Altura Vortex 25 is a solid example of the genre. It has a decent harness and it's pretty comfortable on the bike too.

Made from heavy duty 420 denier waterproof fabric, with fully taped seams, the Vortex features a roll-top closure that buckles at either side to keep things snug and dry.

Like most roll-tops it can be folded over a couple of extra times to pack the bag down a bit if there's not much in it; to guarantee that water won't get in you need to make sure you're folding it over at least twice. Once it's shut you won't be getting any water inside.

I've done hours in the pouring rain followed by a hose-down to get the mud off the bag, with no ingress at all. You could probably take it canoeing and do eskimo rolls and stuff, if that's your thing. So, waterproofing: tick.

Inside there's basically one big 25-litre compartment that's big enough to swallow a change of clothes, your lunch, some tools and more with room to spare. At the back there's a pocket that's referred to as a laptop sleeve, and if you have a small laptop or a tablet then it'll fit fine. I can just squeeze my 15in Macbook into it, although it pokes out of the top a fair way. The sleeve is held in place by Velcro strips so you can take it out if you don't need it.

The main issue with any roll-top bag tends to be finding stuff – because you can't unzip it you always end up rooting around in the bottom, or tipping everything out. One solution to that is to put things in a plastic bag you can pull out if you need to. Generally I've only got a change of clothes, a tool pack and maybe my laptop in my backpack, so finding the right thing isn't too much of a chore; if you're the kind of person who can live out of their rucksack for weeks at a time then you'll probably want something with a bit more internal organisation.

There's a waterproof pocket on the outside that you can put a phone in, and a mesh pocket to hold a lock or your gloves, or other small stuff. And you get helmet hooks for attaching your lid to the back when you're not wearing it. If you're tucking down a bumpy hill then it's possible to lose stuff out of the mesh pocket, so don't put anything important in there. Like, for example, your keys. Just saying.

The harness is well-padded and comfy, with a sternum strap to keep it secure on the bike and a removable waist strap too. The back pads have air channels to try to keep you cool, and they do a decent job; the back's not the airiest I've used but it's not bad, and it's not uncomfortable against your back. The top of the bag sits low enough that it doesn't tend to interfere with your helmet, unless you've filled it really full.

Overall the Vortex 25 is a likeable bag that's very well sealed against the weather. If that's your main concern then it's certainly one to consider.

again they do a very similar simple bag which I have used for the past 18 Mnths without getting my clothes/laptop wet on my comute .laugh 

£30 but it has no outside attachments but do you need them ? 

Lomo one is in day-glo yellow which 'contrasts' with my cycling gear so you stand out rather than a black rucksack smothering your day-glo jacket yes

Lomo one has large refelective strips down the back which again catch the attention of following drivers (hopfully) 

and NO Iam not employe by Lomo

Lomo do a very similar one for 1/3 of the price:
I got one as a freebie at a race last year that has been great.
