Hi all
I am new to the forum and i'm sure it's been asked before but hope you don't mind me asking again
I'm about to take delivery of a defy 1 in approx 3 weeks and i will be using a rucksack to commute to and from work. I shall be carrying shirt/socks/lunch and a few cycyling tops etc. I should therefore not need a big rucksack...what do you recommend? it needs to fit well to the body will little movement and the less sweat the better...thanks
