Okay, I’m way behind the times here: I know that most of you who use the Sawyer Squeeze filter use Smartwater or similar bottles. I’d never tried them (I liked the Evernew bottles.) One of the problems I’ve had with both the Sawyer and Evernew collapsible bottles is that they’re difficult going on impossible to fill horizontally from a shallow stream. (They fill fine if you have a small falling-water source.)

My question: since the Smartwater-type bottles are more rigid, are they easier to fill horizontally from a shallow stream?
