I always take backpacking 2 to 3 days
2 socks smartwool add 1 pair for each extra day
2 ex officio underware breifs
mid weight fleece pants
mid weight fleece jacket
light weight capaline long underware top and bottom
gortext shell jaacket
2 short sleeve shorts not cotton
ex officio zip off pants
1 pair nylon shorts
1 pair boxer shorts
this is what I take in summer and winter if I get cold I can wear it all if I have to but it never gets that bad.
