The difficult middle child? Gourdon 25 is a delight actually! We chose to go super clean with the larger Gourdons, to enable you to get out there looking like a pro.

Gone are the days of pots and pans hanging off the back of your sack, or one of those rucksack covers that never really worked. You don’t need the waterproof cover any more, the roll top closure and dry bag design means it can last any shower and even the occasional dunking. One large 25 litre compartment is all you need for all those bits and pieces for a wild camp away from the masses. Taped seams, durable nylon fabric and the simple design means a rucksack weighing under 600 grams. This includes integrated padded rucksack straps, a hydration pocket, chest strap and waist belt. Your companion for adventures in the UK; you never know when it is going to get a bit damp - but it will eventually...

Top notch

Best pack i have ever bought. It hasn't leaked once, really light and at a good price.
The only things I would add are some elastic to tidy the waist straps (soon sorted with some slim black hairbands)
Place to put keys (Using Velcro I secured a clear pencil case inside)
Quality stuff Alpkit.
A tip for those of you that cycle with it. (I do everyday)
Sandwich your D lock between two pieces of cardboard inside the hydration storage pouch. Keeps it from digging into your back and rattling around.

Day in day out ....

I have used a Gourdon 25 as a my bag for cycle-commuting for the last few years. In all weathers, day in / day out. It is without doubt the best rucksack I have ever had for the job. Waterproof, perfect size for my lunch, a book and a change of gear. I love it and would gladly recommend it to any of my cycling buddies.

Perfect piece of kit

Just perfect. Simple. Practical and well made. Great service and good price too.

Spot on

I've used this for the last few years as a do anything kit bag, and most recently as a bag to commute swimming/running stuff to work in. It's robust, simple and highly admired by many people.

Literally the best bag ever

I've had mine for 2 years and I adore it. It is the perfect size for my daily commute and keeps my clothes happy and dry.

Bloody sweat and tear stained but still going strong

I have had this bag for about 4 years and use it every single day for everything from my commuter bag, to the weekly super overloaded shopping run to caving mountain biking

A week in with my Gourdon 25

This is my first purchase from Alpkit, previously an unknown world discovered through reading 'Microadventures'. All I can say is 'where has this bag been all my life'? It's excellent. It's spacious. It's light. It's stylish. I've loaded it up with shopping. I've carried tins of paint in it this week. I've cycled in pouring rain with my work laptop inside, confident it'll still work when I get home.

As a cycle commuter this is EXACTLY what I've been looking for. It swallows all my stuff. This week I've lugged my laptop and associated cabling, a change of work clothes, my lunch, a hefty D-lock and bike repair stuff. Felt totally secure even when out of the saddle riding uphill.

It seems bombproof and has the features you'd want and none of the extraneous stuff. The minimal design aesthetic just looks cool and the kind of thing that ought to cost a shed load more. Having just read 'Microadventures' I'm now planning my own escapades using the Gourdon.

EVEN better, buying from Alpkit gives confidence it wasn't put together in a sweatshop. I'll be back for more stuff if its all this good!

Countryfile features Gourdon 25 as one of the best waterproof products

Counrtyfile pick three of the best waterproof products to feature in the May 2011 issue. Gourdon is one of the top picks.

Genuinely waterproof day-packs are few and far between, which makes Alpkit's excellent Gourdon packs a rare beast
