CamelBak Octane 8+ Hydration Pack - 2L

Okay, so now I've used this pack for about everything. Biking, skiing, climbing, hiking, trail running and the list can go on and on and on. It's been great for everything! It's really pretty light alone so running with it was no problem. It's comfy enough that biking/hiking was no problem at all. There are enough compartments and expansion that you can fit plenty of gear inside. This was definitely a good find and well worth the dough!

The Octane 8+ is perfect for running and biking. When I`m running in the mountains it stays close to my back and it really is comfortable to run with. You just have to, as mike.mull is saying, get the straps adjusted correctly. When i`m on my bike, whether on the mountains or the road, it works perfectly well. It is not a "big" camelback, and it`s almost aerodynamically designed, which is a positive thing when you are out on your bike. It also has a lot of storage place, I must say I`m a big fan of the expansion system. The only negative thing is that the drinking tube (not the bite valve, the tube that comes out of the hydration pack) is bouncing on the lumbar regions. I use to just turn the whole hydration pack around..

I wore this pack for the Trans-Rockies run (6 days, 106 miles). I was happy with the available space for clothes and gear, the hydration reservoir was adequate, and it's surprisingly comfortable to run with. If you are doing long runs (3+ hours), it's very important to get the straps adjusted correctly. One side too tight or loose will result in chafing at the shoulder straps. Adjusting the drinking tube is tricky also-- the normal arrangement leaves the bite valve bouncing off your sternum.

LOTS of storage space. Fits comfortably while active and doesn't slide around. The only thing I would change would be to have a larger reservoir. I think the they advertise that the bladder should last from 1-2 hours of active use. I'm lucky if I get 45 minutes.

I've had a few camelbaks, both big and small, and I must say this is my favorite. I've also had a couple of other hydration packs, TNF, etc., but this one is my favorite (sounds like I go through a lot of packs, but I have 5 brothers and they get the ones I've slightly used). Every once in a while I run in the ditch on the side of the road 15 miles to the starbucks closest to my house, and this pack is perfect for it. It serves best for any day length or less off road activity (where light and fast is your ultimate end). Pack some zone bars, fruit, water, bike tools, and a rain jacket, and your set to go. If you are going to do something longer than a days length where more clothes might be needed or different layers, I would suggest getting the larger octane.
