Why do you line your pack?

To keep my stuff dry.

What kind of bag do you use?

Depends on which pack.  For the smaller, I use a plastic trash compactor bag. 
I made a sealed silnylon liner for one.  I use a heavy duty contractors 
clean-up bag for my large one.

They say the newer backpacks use waterproof fabrics making the trash bag liner 
unecessary.

I have assumed that the goal of the waterproof fabrics was to keep the bag 
fabric itself from soaking up water and getting very heavy.  Want a real eye 
opener?  Take an older style pack, empty it, weigh it dry, soak it in water, 
dump out all the water you can, and reweigh it.

I suspect taht the all the stitching in a pack can't be effectively sealed, 
given all the stresses that a pack is subjected to.  Even if it could, I 
suspect that the weight of the sealant would approach the weight of a plastic 
bag.

BTW -- Do you how to tell if a pack is waterproof?  If a half-hour after a 
storm you open it and find a gallon of water in the bottom.  Which gets me to 
why I put drain holes in the bottom of my pack.
