that's why I recommend hikers use something like a MSR miniworks or the MSR=
 waterworks.  These filters do not have a outlet hose.  You just screw a na=
lgene bottle into the filter.  When there is only one hose to worry about, =
you have half the problems.  I have a PUR Scout with a nalgene bottle attac=
hment.  Only one hose.  I think that this is a feature that all thru hikers=
 should insist on when filtering. The screw on nalgene bottle is a must for=
 filtering.  This should be the standard.  With the bottle attachment you n=
ow only need 2 hands to filter water.  The 2 hose thing makes filtering so =
inconvenient/unsafe/slow that it is no wonder that many hikers choose not t=
o filter.

With 2 hose system, you stand your bottle on the ground and you then have t=
o worry about your bottle falling over.  And it ever forces you to stand in=
 awkward positions to keep the bottle from falling over.  All that is a thi=
ng of the past with the screw on.

Pass it on.
