My personal experience is that Pur is one of the better brands. My
recomendation for Pur is either the Hiker or Explorer. These both have
Pur's highest rating for removing "bugs". I recomend them because their
pumps work very easily and I have not experienced any problems with them.
Another nice feature is that there is available outlet with activated
carbon in it that will attach to both popular stiles of Nalgene bottles.
(narrow and wide mouth)
The one pump I cannot recomend is the First Need pump. This is because I
had troubles with it clogging very very easily. With the Pur pump, it does
not clog easily, and if it does, you can take it apart and remove the clog.
The Fist Need filter needed to be backwashed, and that made it work about
1 more gallon before it needed to be backwashed again. BTW, the water was
rather clean. With the Pur Explorer witch I own, I have pumped water out
of mud and have had no problems.
Overall, Get the best pump you can afford. I understand that some pumps
now claim to be able to remove viruses. They do this by having some kind
of chemical in the filter, such as Iodine or Chlorine, and these pumps run
out quicker. You will want the pump with the smallest pore size (about .4
microns now, I think).
Allways remember that you should have a backup plan. This could be boiling
for 1-10 min. (depends on who you talk to) or the other option is chemical
purifiers, such as Iodine. One word about Iodine. If you get the tablet
forms, they expire very quickly. Once you open them, they go bad in about
a month. My suggestion is to use what I saw at Philmont in 1991. Polar
Pure is a product that has iodine crystals that you keep dissolved and
under water, thus they keep fresh longer.

The best chair I have found has been the camprest. They are comfortable
and somewhat packable. My other suggestion on this would be useful if you
use an self-inflating pad. ThermaRest offers a air mattress cover that
will convert your 3/4 or full lenght, 1" pad into a chair or lounge. I
have not used these, but have seen them and they look very well built. I
know I have not had any trouble with my TermaRest pad since I bought it for
Philmont in 1991, so I would assume that their chair would be good too.
Hope this helps,
