Wow, that hydrapak looks like it would have been a much better deal. Sure I have 50% more space and waterproofness, but your pack at $30 costs about what I paid for the hydration bladder. The $80 for my pack definitely doesn't seem like such a good deal now as it did when comparing to the $200 list. Oh well. Live and learn I guess. Hopefully, I'll get the fit adjusted right and get used to the dampness of my back as I really love the get on the bike and go nature of backpacks as much as I never wanted to admit it. Throwing a backpack in a folding basket or on a rack and bungeeing it in place isn't that much more work, but I just like the simplicity of hopping on and going.
