+1 Andrew on the rain/wind pants. Rain at altitude is often very cold. Even after it stops, the brush is dripping. Your pants will be soaked within a few dozen yards, then it wicks upward. I take off and store my hiking pants and wear just the rain pants. That way, I have dry pants for use in camp and to start the morning's hike. Hypothermia is a very real danger in the Rockies, especially so due to the almost constant wind, and it is scary just how fast the temperature can drop when the sun gets behind the ridge.
You can depend on the following on the CT, so gear up accordingly or suffer through:
– it will rain, often heavily (especially in July and August)
– it will get windy, often for long periods
– it will be hot at lower elevations and in many long, open areas (segments 2, 18, 19)
– the sun's rays will be intense, especially above tree line.
Here's what I carry for clothing on the CT – both worn and carried. I've used every item at one time or the other.
