I love my convertible nylon pants [convert to shorts by zipper]---I have four pair and wear them most of the time. Shorts may get you by in Texas in summer but up here in the NW, nights get cold. And for that reason, I always pack my LLBean poly fleece pullover, which is cozy warm, yet dries very quickly.

My Outdoor Research hat is nylon & polyester, has a brim, and is extremely cool [in the thermal sense <img src="/forums/images/graemlins/wink.gif" alt="" />]. It folds up easily and can be packed away. The crown is some type of mesh that really breathes as well as being very quick drying.

Underwear for me would not suit you---- <img src="/forums/images/graemlins/blush.gif" alt="" />

Socks: Smartwool or Wool/synthetic blend socks made for hiking [they hug your feet in the arch, don't slip around, so help prevent blisters. My favorites are from EMS and LLBean.
