      >The Apache by Western Mountaineering - Reviewed by Dave Hicks

      >This week's test conditions were as follows:
      >Area: SW VA
      >Three nights sleeping out, or in an open shelter, at 3040 to 4128 feet -
      >e.g., no additional warmth factor from a tent.
      >Minimum temperatures recorded at near by weather station (which was 10 - 20
      >miles away and at 2000 feet): 37�F, 39�F, & 39�F. Assuming a temperature
      >drop-off for terrain, I am guessing that the accurate minimum temperatures

      >Max Wind Speed 14.96 mph

      >3rd night:
      >Wind Speed 4.87 mph
      >Max Wind Speed 9.21 mph
      >Gust Speed 17.26 mph

      >Field Outing Results:
      >Sleeping comfort seems to be the product of what temps you're conditioned
      >(both long term and short term). So, it is not just are you a hot or cold
      >sleeper. A 20� night in the early Fall after hiking up a sweat in a tee
      >during the day will feel cooler than a 20� night in mid winter. [Think
      >about the heating and cooling comfort setting on an
      >air-conditioning/furnace.] That said, I was on the edge of my comfort zone
      >this outing - note this was w/o any additional insulation inside, or
      >the bag. I suspect that were this mid-winter, rather than an early cold
      >snap I would have been toasty. In any case, I could have easily added
      >layers, set up my tent, etc to have survived 20, or more, degrees lower.
