Thanks for the post yeti, I had been waiting for them (guyot designs) to get more backpacker bottles in. I just ordered another one for another kit I have which puts me at 3. I have 1 that I carry everyday for work now and removed it from one of the kits and need a replacement.

I don't know about the standard bottles from them, I know the back packer can rattle with a cup due to the taper design but I had bought a carrier from US Calvary that keeps it quite, but a bandanna around the bottom will do as well. I have boiled water in these bottles and the one I carry to work has several dents from me dropping it on concrete but still remains water tight with no cracks and still going. It's like a battle bottle. I like how they keep the water cold for a long time even being non insulated. I did a quick search as well and could not find the link as well.
