Got my 3L bladder today.
It fits great in my CamelBak Trailblazer that I've had for years. It has 2 holes coming out of the bladder section, which works great for the drinking tube and the pump.
My old Platypus bladder was working great, but I was intrigued.
The Geiger is very well made, as was previously mentioned. Fittings are top notch, as are hoses, etc.
Very well thought out, and very well made.
I didn't think not having to suck would matter, but walking around the house with it on, it really is nice, and makes a difference.
One of the coolest things is that I can remove the pump and drinking tube from the bag without feeding them thru the holes in my pack, and remove the bladder for cleaning. It's pretty rad.
The only "con" I can think of, is that when pumped up, it can round out your pack a little. Before, my bladder would kind of mold to by back. With the Geiger, you can feel it a little. But a little loosening and adjusting of the straps fixed that.
Because of my stupid post office, I didn't get the filter yet, but that part was the selling point for me.
I think it's cool to be able to essentially never run out of water.
Will this thing filter pee?
Anyway, Geigerrigs are sweet.
EDIT: Oh, and when I emailed Geiger about the post office sending the filter back, he responded immediately and said he'd take care of it. GREAT customer service.
