This is the most comfortable pack I have owned so far. I use it for day hikes and it fits everything I need. It is stable, very adjustable and the hydration bladder is extremely easy to use. It could use a couple more internal pockets to keep smaller items together and from settling at the bottom.

I don't actually own a Blowfish; I borrowed one. It was the first time I used a hydration pack. I can't review the hydration portion because I didn't use the reservoir; I'm not crazy about the concept because they seem to take too much effort to clean, and standard waterbottles are so easy to clean-I just unscrew the top and let them air dry.
What I CAN comment on is the fit and capacity of the Blowfish.
I used this for a one-day, 13 hour bike ride. Here's what I fit in it: various bike tools (except for tubes and tire levers), spare cables,lube, brake pads, chain links and pins, wallet, eyeglasses, two full waterbottles, 2 sandwhiches, 2 PowerBars, a candy bar, tights, armwarmers, two 8oz. cans of soda, and a 20oz. bottle of soda.I removed the reservoir since I wasn't going to use it.
This thing fit so well: it didn't sway when riding out of the saddle, the waist strap is so thin it didn't pinch my waist like my fanny pack does, it had plenty of pockets to organize my stuff, reflective striping and a strap to hold a flashing taillight; the shoulder straps were comfortable and easy to adjust; the sternum strap kept the load from pulling on the shoulder straps, and it sat in just the right spot on my back.
With all that I fit in the pack, I never even used the accordian-like expansion feature, but I was glad it was available.
I was just in awe of the amount of stuff it held without feeling bulky and without interfering with riding by flopping around.
I borrowed this because the lumbar pack I ordered from another company did not arrive on time for my ride. I am so pleased with the Camelbak that I'm returning the lumbar pack I ordered and I'm going to buy a Camelbak of the same size or larger, even if I don't like the hydration feature; the pack alone is that useful.
The only con I can think of is I wish there were external pockets you could access without removing the pack, something that would hold a sandwich and/or sunglasses, perhaps.
