A common question seems to be : What's in your bicycle bag?
The bag they are referring to could be my seat bag found under most of my saddles, one of my messenger type bags slung over my back on the way to work or the store, or maybe my Camelbak on the way to the local mountain bike trail.
Here's a deep confession, I have a bag addiction. Come look in my closest and there are at least 4 messenger bags, 4 bicycle specific back packs, hydration bags and then panniers are end less. Constantly the search is on to find the most stylish, yet functional, bag possible.
