[at-l] clothes for AT thru hike?

[Tom Mantooth]

I was wondering if someone who has hiked the AT or any other long trail 
could assist me with a question I am  trying to decide concerning the 
weight of various clothes on the AT.

This has to do mainly with winter hiking.  I am starting on March 10th.  
I was wondering if it is better to purtchased lightweight clothes and 
wear more layers that to say use midweight?  I have for example notice 
that 2 lightweight under garments some time weight a few Oz less that 
one midweight.  I have read in a couple of Hiking books that using 
lighter weight clothes and using say 4 leyers instead of 3 is lighter 
yet just as warm because of the cusion of air between layers.

Has anyone had any experience with this?  I would appreciate any 
pointers that anyone can provide.  Since I shall be 71 years old when I 
start I need to keep the old body as comforable as possible but with the 
lightest weight that I use.

Thanks,
Tom
