Alpkit Gourdon 25 drybag rucksack



A do-it-all bag that offers excellent protection against the elements, simplicity and outstanding value

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

We'd all agree that it can be pretty morale-sapping to grind your way to work through wind and rain, whether it's a blustering headwind in summer complete with sudden heavy showers, or driving rain and howling winds on a winter's morning. But the sucker punch is delivered when you find your change of clothes and your pork pie wringing wet in the bottom of your bag. The trick is to be prepared, and the Alpkit Gourdon 25 dry bag rucksack is certainly a good first line of defence against the elements.

Alpkit produce all manner of outdoor kit, from torches to tents and everything in between. Their dry bags and rucksacks are some of their best known and sought after pieces of kit. They're particularly popular because they're adaptable, hard wearing, and can be used across a range of different sports and activities, cycling being a key one.

The first thing to point out about the Gourdon 25 is its simplicity. There's one main 25 litre storage compartment with a buckle-fastened roll top, and a narrow pocket that can accommodate a 1L hydration pack. That's it. It weighs less than 450g.

For a bag that's so simple it's surprisingly comfortable to wear. The shoulder straps are padded, and there's a thin waist strap and sternum strap that keep the bag securely in place when you're in full flow on the bike.

The vacant hydration pocket contains a removable padded section that gives the back panel some extra structure and makes it comfortable against your body. This is something other bags of a similar design often lack, and you find yourself being jabbed in the back by the contents of your bag. No such problem with the Gourdon.

The main compartment is big enough that you can easily fit in spare shoes, a change of clothes, packed lunch and a loaf of bread. Easily enough for the average commuter or day tripper. The top of the bag pinches together and rolls shut before being fastened with a durable buckle; this can then be fastened to the bag with two toggles.

The single large compartment makes things easy – just throw everything in – but the lack of pockets can be a drawback if you want somewhere to store smaller valuables. A separate pouch is the simple solution, though that means shelling out extra.

The version we tested contained a clear plastic window down the length of the bag. This is optional and only included on two of the colourways available. It's really handy if you've stuffed your bag full and can't remember if you've included your dry socks for the office. No need to open the bag and fish around, you can find out at a glance. It's not so god if your y-fronts or expensive valuables find themselves pressed up against the window for all to see... You can find yourself spending extra time 'tactically packing'.

The bag is constructed of Taslan Nylon, a water repellent and durable material used across a wide range of outdoor equipment and clothing. It's also lightweight and quick drying, making it ideal for this kind of bag. The seams of the bag are all taped too, giving great peace of mind that you're not going to arrive at the office with a soggy change of clothes. The nylon is pretty hardwearing, but if you do happen to nick or tear it then Alpkit provide you with a few handy iron-on patches for repairs.

There are four colour options available: the Flo Yellow we've reviewed here, Black, Kelp (dark green) and Chilli (red). Only the Flo Yellow and Chilli versions have the transparent window, the other two have solid material outers.

Daytime visibility is great with the Yellow and Chilli options, but the Black and Kelp aren't great choices for standing out on the road. There are no reflectives and nowhere to hang or strap a light, although the Gourdon isn't a cycling-specific bag so maybe they can be forgiven for these omissions.

So far, so good. And, even better, the Gourdon will set you back just £22.50, an absolute steal. If that wasn't enough value for money then Alpkit will throw in free delivery, a 123-day returns policy, and a three-year warranty. That's pretty much the dictionary definition of value for money.

I have had two of these.

The first was 20 litre but it split in the end as it wasn't quite big enough for my purposes, in it's defence I really did kick the arse out of it on a daily basis for two years including mountain biking.

I bought a second stealthy in 25 litre and the extra 5 litres makes all the difference, it's been used day in day out for the work ride, shopping, walking and generally dumping anything in it. Again this one is two years old and gets thrown about a lot - it's started showing small holes here and there so it will be replaced soon.

For the money they are very good commuting and outdoors bags as they remain genuinely water tight for a fairly long period of hard use, more if you use the patch kit included.

Great bag--very practical

fenix | 8 years ago

The OverBoard is nearly three times the price....

I just got a wide strip of 3M reflective to stick down the back of the bag. Cost under a quid.

Great bike for all sorts of activities - waterproof.

I did an adventure race with a conventional rucsac - 12 hours plus in pouring rain and it soaked up the water like a sponge. Next time I'd use the Alpkit.

Awesome bag,

Personally I'll stick to my Over-Board rucksack if I need this amount of capacity - it comes with reflective strips, an internal pocket for valuables, an external mesh pocket and bungee straps and no window to show off my kecks (yes I read the bit that said it was optional)

Most of the time though I use a much smaller/cheaper pack (an Aldi special) with my clothes inside a dry-bag (a plastic bag works well too!)

Although the Over-board is more than twice the price...

I'm a big fan of Alpkit's stuff (and I promise I've not registered just to post that!) - I've got the Stealthy Gourdon (as they call the black one) and it does exactly what it says on the tin. It's a well-priced drybag with comfy straps.

The roll top and the 'gaping maw' style of packing does mean a faff if you're taking things in and out, though, even if you do add some sort of packing system.

My yellow Gourdon 20 has been on bike commuting, MTB, hiking, mountaineering, picnic-ing and general lugging duties for about 3 years. It has thrutched up greasy limestone chimneys in the mountains, been covered in mud so much that it's hard to tell its original colour and been out in rainstorms so heavy that I may as well have jumped into a lake. It hasn't missed a beat and is still, amazingly, waterproof (if a little scruffy). Alpkit make really good stuff in general.

Not a rip off, worth every penny.
Had my 25 for 2 years and still going strong, no broken buckles or any issues at all, you wont find a lighter waterproof bag, its comfortable and doesn't move around, another good thing about the bag is you can roll it down to reduce the size quite allot so for those days when you are not carrying allot it can become more compact. I have also even ironed on some ebay reflective panels to my bag so it looks like a 'hump cover', highly recommend this for light to medium lugging. Will get another whenever it disintegrates.

Great minds - I did exactly the same to my black Gourdon 25, and it worked perfectly this winter. This is a superb bag, and the second one I've owned - getting about 1.5 years out of each one.

However, I've now replaced it with an Overboard 20L - which offers the same capacity (carries laptop, clothing, shoes, washbag, lunch), but with better padding and more features (handy external mesh pocket & internal zip pocket) for not a lot more. It also suits me better as it's shorter than the Gourdon, which I found rubbed my lower back when full - I'm quite stocky.

I've got the smaller one, had it a few years and it's a great all round bag. Served me well up mountains, and down the beach as well as carrying my togs to work. The smaller one also has two pockets on each side and elastic cord to compress it if it isn't quite full.

My only criticism is the faff opening and closing, a zip would be so much easier, but I guess a lot less waterproof.

bloody rip off
