Perhaps the best material for sleeping bag vapor barrier liners is the silicon coated 1.4 oz. rip stop nylon used by Jack Stepehnson in the manufacture of his exceptionally light tents. Stepehnson sells this 62" wide material for $10 a yard, or for the the ultimate, $25 per yard for the aluminized material to thwart radiant heat loss. Stephensons 22 Hook Rd. Gilford, NH 03246 (603) 293-8526 If you have ever owned a Stepehnson tent the justification for his high price is clear. His 2.75 lb 2RS mountaineering tent is quite exceptional, albeit without peer in the cost department. Camp 7 used to manufacture VBLs from urethane coated 1.5 oz ripstop, but all urethane will eventually emulsify while the silicon material is stable. VBLs add substantially to sleeping bag utility. Our ski touring experience in the Pacific Northwest suggests about a 12-15 degree advantage -- well worth the weight. -- Richard G. Mitchell, Jr. Corvallis, OR 97331 U.S.A.
