recommend me a back pack
 

That is small, light, tough and high quality. I just need to hold a few things. I have north face borealis right now, its a quality bag but just overkill for what i need

thanx

I have a camelback fourteener. Remove the bladder, room for a change of clothes and food for the day. It's also vented across your back.

Klick fix Rixen & Kaul, KLICKfix Adaptersysteme Fahrradzubehör, Solingen, Taschen, Körbe, Werkzeug has a few backpacks that you only have to wear once you get there .
riding the bike, it clips onto a few brackets of theirs , you can fit on either handlebars or seat post..
