I know that this opens up a can of worms in the "what to wear" category, but I don't head up to 14K without 1) some thin waterproof shell 2)an insulating layer to wear under it, ie, a down sweater or lt fleece (I have worn this combo down to 26F). Keep in mind that for MW85, Whitney seems to be a quick morning workout
for most people, it is an all-day into the early evening trek that ends with one being either tired or near-exhausted.
I agree, MW85, I don't pack a closet, either. For a 3-day Whitney b-back trip (that included an overnight on the summit at temps of 19F) pack weighed 21 pounds, and I did not have to compromise on warmth (it was late Sept with a huge storm that hit less than a week later)
