That is a good question. Perhaps I should conduct an experiment and figure it out…
But I think it’s probably closer to two liters.

I’m guessing the 100 oz capacity is unzipped. What is the zipped capacity?

Great pack, I love mine. Only used once so far, on a 30 mile ride. LeftLane Sports has it right now in black, for $45. Can’t beat it!

@Jeff and abegold, the zipper is just separated… it didn’t actually tear out of the fabric or anything. Abegold, I will have to give that a try!

As for the zipper inside of the hydration pack, just think of a big ziplock bag with a really burly zipper. Not the ones with the sliders, but the older-school ones.

@maddslacker, as I mentioned in the blog post, when the reservoir is zipped up there is significantly less water storage. I had it zipped at buff creek and on Kenosha Pass, and I ran out both times. Granted, those were really long, pretty hot, rides. If you know you’re going to be out for a long while, I’d recommend opening it all the way up.

@abegold’s second comment, I sweat a lot no matter what I’m wearing, but the back of the pack has raised mesh panels designed to create channels of air flow to cool your back. I’ve noticed that if I have the pack overstuffed (see the blog post), the air channels get pressed pretty hard into my back cutting off air flow. But if I have the pack loaded moderately with the reservoir zipped, the air channels worked better.

Also, I couldn’t find any official stats on the website for gear storage space (otherwise I’d have included it)… the only stat I could find is that the pack measures 18? x 9.25? x 4.25?

What’s the back panel like where it contacts your back, for sweat? Hydrapack had a breathable mesh panel in the past, do they still use it?
Cubic inches or liters of storage?

3 liters, and you still ran out at Buffalo Creek?

When a zipper seperates usually just squeezing the zipper pull with pliers making the distance between the top and bottom of the pull slightly smaller will result in a tighter and perfectly good zipper. This works on any zipper!

So how does the zipper in the reservoir work–is it like a zip-lock or something?

And the busted zipper… did it rip or did it just get off track? I would think if it is off track that might be repairable…
