And neither one of those will filter sufficiently. You need to add chemicals after the Frontier - all it gets is the largest stuff aka cysts and protozoa.

The Life Straw you can look up reviews for - but there is likely a Big Reason it isn't available at REI or any of the usual vendors for ultralight hikers.
