Can the sawyer mini filter screw onto this?

YES!! The solution is easier than you think! Replace the white sealing washer with a thinner one. Ideally about 1mm thick, or between 1/16" and 3/64". May be hard to find, but a few minutes with an Exacto knife and some faucet packing material from the local orange hardware store will have you in business. Just trace the original gasket onto the rubber sheet, cut, and no more leaks! (Warning: the washers used for your garden hose are still too thick......yes, I tried). I can verify no leaks even with the Sawyer flip-cap closed (it wasn't intentional). Cost me nothing (I had the material already), and took me about five minutes of perfectionist cutting.

Where is this made? China? U.S.

It says on the package that it's made in the USA. It also has Seattle stamped on the container itself but I don't know if it's made there.

How wide is the cap? I want to use a Lifestraw through it.

The opening is only about 3/4", a lifestraw will not fit into the opening. You can look into getting a Sawyer mini filter (about $20 at Walmart). The Sawyer has the same thread size as the Platypus bag. Just screw the filter directly to the bag. You can modify the Platypus drink tube to fit onto the clean water side of the Sawyer filter. It weighs 2 oz and can filter up to 100,000 gallons. The flow rate is good as well. Hope this helps.

is there a way to get replacement cap? I bought 2 of these and my Boy Scout lost the cap to one during a flash flood! on his hike?

You can pay between $3 -$6 for a replacement cap. If I were you I would just buy a Smart Water (bottled water) bottle and use the cap off of it. I think there are 2 different types, plain cap and sports top.

Very versatile, very strong, very pack-able and very light - ideal for traveling

Have several of these now. Really good for travelling and taking backpacking. They fold up really small but hold a lot of water - slightly more than the 2 L advertised. They're very strong - I have a Aquamira Frontier Pro and I have to squeeze the Platy Bottle to get a decent flow and the Platy takes my best squeezes with ease. I have full confidence in these nd best of all they dont have a nasty plastic taste.

Platypus bottle

Does what it sets out to, folds down nice and small, lightweight, and carries waterEvery one needing a way to carry/collect water while out on te hills (or anywhere else) can't really go wrong with one of these in their bag.

Fine

The mechanism could be better, but it's the best thing for holding 2 litres of water, when you need it.
