Like that G 02. Wide enough top for a cleaning brush is a must for me. Maybe most of you use just water, but tea and other drinks that can get moldy residues often go into my bottles. That is why I use the wide mouth bottles, and not the bladders.
The cap looks quite sturdy also, with a straw hole that will take a nylon bolt for a cap retainer. Wonder what the capacity is, the recycle #, and the weight, of course. With a little lurking around the drink coolers, will find out.
These could replace my #3 peanute bottles - no word here on #3's yet, though.
