      Backpacking Background:
      I'm in Montana where I'm enjoying the summers and becoming re-
      acquainted with winter. Now that I'm back above the snow line, I'm
      attempting winter camping and snowshoeing. I'm a lightweight
      backpacker mentally, if not always in practice. I've gotten my
      summer multi-day pack weight down to 19 lb (9 kg) with a tent, but
      winter backpacking is still new to me, and my winter pack weight
      hovers around 25 lb (11 kg).

      H2O Amigo Description:
      The H2O Amigo is a gravity-fed water filtration system. The system
      uses a carbon filter cartridge with a 2 micron pore that is
      advertised to remove 99.8% of waterborne contaminants.

      Field Information:
      I tested the H2O Amigo in Montana, Wyoming and New Zealand in
      temperatures from 35 F to 70 F (2 C to 21 C) and at elevations up to
      7500' (2300 m). I filled the Amigo from streams, rivers, and lakes.

      Experience with the H2O Amigo:
      I really enjoy the H20 Amigo. After the bag is filled and hung, no
      effort is required to filter the water. I really appreciate having
      extra water storage at camp, and the nozzle is great as a faucet for
      washing hands and dishes.

      Filling the H2O Amigo:
      The quickest and easiest way to fill the H2O Amigo is by submerging
      it into a water source. As the weather got colder, this became less
      enjoyable. Not only did my hands get wet, but when filling from
      lakes I had to wade a few feet out into the water to get to an area
      deep enough to submerge the bag. My hands and feet got quite chilly.

      Filtering water:
      After I was clued into the fact that the H2O Amigo hose can connect
      directly to a Platypus, I had no problems filling my hydration
      bladder. I collapsed the bladder to get the air out, hooked the
      filter to the nozzle on the bladder, and turned the filter on. I
      didn't have to worry about the filter hose dragging in the dirt and
      didn't have to watch the system to make sure water didn't overflow.
      Water filtered into the Platypus until it was full and then stopped.
      I just had to remember to turn the filter off before disconnecting
      the hydration bladder.

      Hanging the bag:
      I never had any problems finding a place to hang the H2O Amigo. I
      tend to camp in wooded areas with plenty of trees and could always
      find a branch the appropriate distance off the ground. I didn't have
      to use additional rope or a carabiner to secure the bag, but carried
      them along on trips just in case. When I did camp in areas with no
      trees, like Joshua Tree National Park, there wasn't a backcountry
      water source to filter from anyway, so I carried enough water for the
      whole trip and didn't worry about filtering.

      Filtering rate:
      The lake I filtered water from in New Zealand was full of silt and
      gave the pre-filter a workout. It also reduced the flow rate of the
      cartridge considerably from 0.70 L per min (24 oz per min) to 0.40 L
      per min (14 oz per min). After backflushing the cartridge for one
      minute using the flush bulb and my sink, the cartridge flow rate
      increased to 0.52 L per min (18 oz per min). I don't mind the slower
      rate of filtration. In camp I always have something else to do so
      waiting a few minutes for the water to filter is not a hardship. The
      cartridge filters well at this slower rate, and I can't tell how much
      life is left in the cartridge. There isn't any indicator besides the
      flow rate to tell when a cartridge is used up.

      As the weather got colder, I was very careful not to let the filter
      cartridge freeze. I made sure to empty the cartridge at night and
      store it in my tent. I didn't have any problems with water from the
      filter getting my gear wet, but sometimes I got a little overzelous
      in blowing water out of the cartridge. I would blow on the nozzle
      where the unflitered water goes in. My hiking partner commented that
      when I got giardia and he didn't we'd all know where it came from.

      The H2O Amigo has born my abuse very well. The bag looks like new.
      The handles show some scuff marks, but are still sturdy. The stuff
      sack's seams are intact. The hoses are fine. The one mark of wear
      is on the cartridge. The arrow sticker indicating which side the
      contaminated water goes in and which side the clean water comes out
      is showing some wear. The other stickers on the cartridge that give
      the name of the product and manufacturer's website have held up
      fine. The directional sticker is paper while the other stickers have
      a plastic coating. Paper stickers don't like water, and this one is
      peeling off. When it's gone I will have to rely on the small
      words "in" and "out" stamped into the plastic to tell me which way to
      place the hoses.

      The H2O Amigo is great. No pumping required. The Amigo filters
      while I'm doing other things, provides excellent water storage in
      camp, and is very useful as a tap. I wash my hands and my dishes
      more thouroughly when there's such a readily available water source.
      Thanks to ULA equipment for providing such a useful piece of gear.

      No pumping.
      Nice to have a spigit around.

      Challenge to fill the bag without getting wet.
      Directional sticker is peeling off.
