VB Bag Liner

This vapor barrier bag liner is a good choice for increasing the temperature rating of any bag (down or synthetic). By preventing evaportive heatloss the VB bag liner will keep your bag's insulation dry which is especially important for multi-day outings. The aluminized ripstop is no longer available so we now construct these with 30 denier siliconized nylon fabric with a choice between black, red and slate blue.  The VB bag liner features a 36" #3 YKK coil zipper for easy entry/exit and improved venting. An elastic one-hand cinch cord allows you to either keep or release the heat.
