ok, so I had my bag out for a good long ride last weekend (middleburg, the plains road, winchester, etc.). The upside - it works great for those few small items you need to carry and makes getting gas, etc. way easier than a backpack since you don't need to remove anything to get to your wallet, etc. It stays put at highway speeds and you can't tell it is there when you are on the bike. The downsides - I was right about the zippers. They are cheap and a little bit hard to work so you have to be careful with it when opening and closing. I'm used to burly zippers and these are kinda flimsy so I open and close it gingerly since I don't know how well it would survive a zipper jam if I catch the inside material. The external biner and key ring holder thing are not confidence inspiring so I don't use those. I got some compliments from other riders that like the idea of a fanny pack when riding, but feel like tools walking around with one. They said this one looks vaguely tactical so the thoughts of the others was that it was a step up from a fanny pack. Now that I have tested it and it works for me, I would pay more (2-3 times as much) for a really well constructed one. If anybody knows where you can get a "good" one let me know. I would really like something in ballistic nylon or burlier cordura with waterproof zippers or at least mil grade YKKs. That being said, I am keeping it and will use it regularly until I find the same thing in a bit higher quality.
