Funny you mention this, I was searching for bags till I was just frustrated with either options, price, or size. I was looking for a nice pack that would offer a decent amout of storage and not be so bulky. I spent $65 on a hydra pack that looked like would work, but ended up still being a little to small. I was also looking at the Alpinestar backpack but man I couldn't justify spending that much on a backpack. To make a long story short, after I found that the hydrapack was to small I needed a larger backpack and quick for next day to ride to work. Went down to walmart and purchased an Outdoor backpack (that is the brand) back in the camping section for $15, its light and doesn't shift around on me at all, does the job without breaking the bank. Hope this helps you in making your decision. :thumbup:
