zipper basics

read what stevenson warmlite thinks about zippers here:http://www.warmlite.com/bags.htm about 1/3 down the page

good point. seems the smaller teeth are less likely to snag the fabric.
and they seem to have a good track record for them.

something that caught my eye on that site...

Both Down and wool can absorb many times their weight, within the fibers, with no effect on insulating ability

true for wool but everything i've ever read says the complete opposite about down; that down loses 90% of insulation value when wet.

Constant source of debate on that topic. Studies show this, studies show that; basic lesson keep your stuff dry!

Not matter what they say Keep your stuff dry... EVEn the modern synthetics which "don't absorb water" are miserable and cold when wet. Its the energy required to evaporate the water that chills you, even if the insulation retains much of its insulating value you're still gonna be COLD.

DOn't ask how I know this...
