Smartwater bottle alternative discovery

OK I gave up on uploading an image, but these ecos soap bottles fit the sawyer squeeze and sports cap to a smart water bottle. They weigh 42gram without stickers as 1lt smarts weigh 27grams. For a little over a half ounce, the bottle retains it’s shape after squeezing, as my smart water bottle barely holds water from how crushed it has become. Plus it is a rectangle shape which might ride in a front or side bag pocket better.

Nice shape and size, but something under an ounce would be ideal. Every time I’m in a store I look for a square or rectangular cross-section plastic bottle that’s no heavier than a smartwater bottle and has the right threads, but no luck so far. It would also be nice to find a 1 ounce, 1 liter bottle with a wider cap (like the Gatorade caps) for use as a pee bottle.

Square or rectangular bottles are pretty much assured to be heavier. Simple geometry tells you that it takes more plastic to enclose 1 liter of water in a rectangular bottle than in a round one. Plus the round bottle can have thinner walls since it does not require structure to hold its shape.

Nice find, but I would be leery of lingering soap tastes – yuck.

@paul-1, the surface area of water is the same when it is not compressed?

Why not use an Evernew bag? 900ml weighs(29g) less than the bottle and is very easy to squeeze for Sawyer filtering.

36g for 1.5L,
