I wasn’t convinced with the lack of the pockets too before I bought it. I used to use an old North Face Hammerhead for ages. It had plenty of pockets, much more then the Deuter.
But after I made my mind and got the Race EXP I’ve never looked back. It’s just got one compartment (with a section for hydration bladder), where I stuff a pump, inner tubes, small bag with my tools, food (I eat a lot…), extra clothing – and if I need more room an all-around zip extends the capacity for extra 3 litres.
Small zipped pocket is good for wallet, phone, keys, small bits and pieces. Two side mesh pockets are roomy: normally one takes a handful of gels, the other a bottle of lube and one or two bananas.
Even when the bag is very heavy (like on “office clothes changeover day”) it is still amazingly comfortable to carry – no matter what and how you stuff into it, the area that goes against your back feels always the same – and that is the best feature if this rucksack!
