I'm a teacher and a dry days commuter. I have a Vaude Office bag pannier which until now has proven a beautiful buy.
However sometimes I need to go shopping or take extra stuff to school and I have been looking for an extra bag. I have read all the posts on Arkel Bug and I simply love it but it is a bit expensive.
I've also been looking at backpack with a mesh which keeps the back pack away from your back allowing for air to cool you down avoiding sweat. This sort of backpack I could also use for longer mountain bike exits. Has anyone tried this? Does it work? I don't want to arrive to my school with my back dripping sweat, I ride in my work clothes and that's rather uncomfortable.
