      Actually, after it was stiched to the shell (or liner as the case may
      be), and then both layers were attached together, there really was
      no shifting. We will see though how it works on the nylon, which
      is more slick. Right now its on cotton muslin which "sticks" to the
      insulation. I'll keep that in mind, thanks.

      Sure, it will be good to compare. I will have the top layer be a
      ripstop nylon, which should breath enough to let it evaporate.

      I also considered putting in some "drain holes" in the outer shell
      near the lowest point of the depression under my weight. The
      idea being to have small drains for condensation to escape, but
      still not let the wind wisk away all my accumulated heat.

      Not sure yet if I will do it though. I'll try w/out first.

      Not really, I guess I assumed it didn't add much volume so it
      wouldn't make much difference to remove it before I put on
      the SnakeSkins. I'll have to give your idea a try though and
      see what kind of difference it really makes. Thanks.

      They do sell Primaloft as follows:
      Weight Thickness Price
      Quilted Sport - 1.8oz/yd - 0.4" - $5/50/yd
      Unquilted Sport - 3.0oz/yd - 0.6" - $6.00/yd
      Unquilted Sport - 4.0oz/yd - 0.8" - $8.00/yd
      Unquilted Sport - 6.0oz/yd - 1.2" - $11.75/yd

      They also have Hollofil II for $5.50/yd, Polarguard HV at 1.5" thick
      for $10.50/yd.

      A correction in the SilNylon, its in 65" width bolts and is $9.50/yd.

      They're 1.9oz rip stop is $6.00/yd for 60" widths, Micro denier
      ripstop, 1.4oz, is $8.50/yd.

      10% off 10-19 yards bought from the same roll, 20% off for 20 or more
      yards from the same roll.

      If you like fleece, this is your store. Every imaginable kind I have
      ever seen. I really don't work there, but I sure love browsing there.

      If you make it to Portland, then you'll need to drive another 90
      minutes to Corvallis to get to the store. They're open for walk in
      business Tues-Sat, 9;30-5:30, or phone orders Mon-Sat.

      Really, I don't know anyone who works there and I don't make a
      comission, I'm just really impressed with thier selection.
