Many thanks to the Mad Duo and team for adding me as an auxiliary ... 'roo's on the barbie any time you rock up ...
My first item from a bundle of goodies from Propper that I am going to cover is their nicely branded "Limited Edition" Liberty Bottle. I've seen these good looking bottles in the past, but so far, had stuck to either my much loved but slightly unreliable 1L SIGG or the very reliable widemouthed 1L Nalgene.
The Propper Liberty Bottle makes a very nice addition to my collection, and let me tell you why.
Made from 100% recycled metal aluminium, with 100% recylcalable materials in the cap and bottle, the Liberty Bottles are both light, strong and friendly to the environment. Like the SIGG bottles, the Liberty bottles are formed from billet plugs, giving a seamless construction and are lined with a flexible and food grade coating, which ensures no flaking or chipping when the bottle itself is dinged and dented (as may happen with the hard wear some of us are guilty of putting our hydration systems through.
This coating exceeds FDA requirements and provides a non-toxic and non-leaching surface that ensures no heavy metal leaching or porous surface are present for bacteria to build up on, keeping them sanitary for longer.

The bottles are independently lab certified to by 100% BPA free, for those worried about that kind of thing.
The fact that that coating is white means that visual inspection of your bottle for both fullness, and skunge buildup is a lot easier than if it were a darker colour. I really liked this.
Three locking lugs on the rim of the bottle are not obtrusive enough to be a bother when either filling up the bottle, or drinking directly from the lip.
The taper of the bottle also acts to smooth out the pour, much like a wine bottle, all part of the design

At 700ml (24oz) this is a good sized bottle for me when I don't feel the need to carry a whole liter around.

The silicone rubber nipple fits snugly against a ridge on the cap to keep it crud-free, and covers the vent hole when depressed. The lever also acts as a carry handle, and the whole assembly can be broken down to clean all the parts.
The only drawback I've found is that if I've let a cold drink warm up, or hold the bottle around any air-space, the heat of my hand can expand the air inside enough to make it spurt my drink up out of the straw when I flip the top.
Liberty Bottles cutting-edge cylindrical printers have done a great job on Propper's design, laying down graphics you can feel. I really liked that tactile diamondplate addition, and the surface material has taken a few drops and knocks already with no sign of wear.
