I was looking for a rucksack that would limit the sweaty back with the commute to work, this rucksack goes partly towards the non sweaty back but where, there is no frame to keep the rucksack away from the back you cannot but help sweating and leaving unsightly marks on your back. Proper dry cycling tops help the unsightly back but for the cost of the rucksack, I would have been better with a framed version that keeps the rucksack away from the back. The airflow system does not work that well, in this rucksack, however, on the positive side I can have a full change of clothing, towel, and lunch in the rucksack and the glow in the dark rain cover and helmet net I find very useful.
Would I buy it again, on the one hand I don't regret buying it, but no, I think the cheaper rucksacks would have sufficed or I would go for a little bit more expensive and purchased a frame version, but I was a bit unsure about the weight with these ones.
