As always, Jack Stephenson's products are not for everyone,
especially those expecting to leave anything at all to their
children.  (We don't -- enjoy it now Annie).  His new tent fabric
is silicone (not silicon) treated, but in a way different from
the urethane materials.  The urethane's ripstop fabric contained
filler fibers to which the urethane adhered when applied from one
side.  The silicone ripstop is different fabric, without fillers,
onto which the silicone is coated on both sides.  It does not
adhere to the fabric, but to the coating on the other side of the
fabric through the intercies in the warp and woof.  So both sides
are "coated" but in fact form a bond throuth the material, the
fabric itself is inherently stronger, and the silicone is not
subject to deterioration from moist storage.  I is also
supposedly more UV resistant and a bit lighter with a higher
vapor pressure.  All in all super stuff, or so it sounds.  My
tent is 5 hours old so I can't tell you how well it will wear,
though it weighs an honest 4lbs. 7 oz on a postage scale and that
is the 3rs, the three+ person with large side windows and big
doors.  This is not a canoeing/kayaking tent but well suited  for
climbers and ski touring where weight is critical.  When paddling
we principally use VE24s now (the Guide model is great with the
extra thick floor and the SS zipper sliders and no vestibule to
collect black flies). The best ever was the Pole sleve Oval, but
no longer made.  Many tent manufacturers don't understand arctic
travel and make large dark colored door way panels and insist on
vestibules.  Stephenson will sell his silicone coated fabric to
those who wish to make VBL, or will make them for you for a hefty
price ($100 I think).  Stephenson says the silicone fabric has
completely outclassed the urethane stuff he used to use and that
is still in use elsewhere.  Time will tell, but his reputation
and our experience suggest that the materials he selects are the
very best.  Call and chat if inclined.  We use VBLs on all winter
trips but do not attach them to the bag or build them in as was
the case with Stephenson's bags.

Happy paddling (and skiing soon).

And anyonw going to the Bahamas this Xmas?  We would be glad to
see you.

Rich, Eleen and Annie
