The FastBack 70LS Hydration Pack lives comfortably just left of center on the back of your seat. It's the solution for lowracers and other hard-shell bikes & trikes with limited tire clearance, as well as Bacchetta EuroMesh seats. Stow away a 3L CamelBak Bladder or some gear. Get the Double Century instead and wield another pack of power! Have a 70LS already? Get the 70LS to Double Century Upgrade Kit and boost your capacity!

Some disappointment
Bag works good but I’m disappointed that it wasn’t insulated.

Easy to install, works like a charm
I bought this for my Azub SIX, and the instructions were easy to follow. I am using it with a Gregory 3L water bladder, which fits in nicely. All in all, very happy with this purchase!

ICE VTX Bag
It took a while to figure out the best way to attach this to my ICE VTX. In the end it works well and can carry spares, tools, wallet, cell phone etc

Well made, quality piece of gear
Sadly, the 709LS is not specifically designed for the ICE Adventure HD, so there are challenges to be met. I've done some work arounds and have it useable (tho I really need a longer drinking tube, but that's a different product). However I think there's room for improvement in the way I have it slung. Having said all that, it's a quality piece of gear and, given the 105 degree summers around here, I'll probably get the Double Century Expansion Kit.

Excellent bag. Highly recomended!
I bought this bag so that I could carry a 70 ounce hydration pack on my Challenge Fujin SLII, and it works perfectly. It securely holds my hydration pack low on the left side of the bike and out of the way of everything else. I could not be more pleased with this bag. Excellent product!
