Thanks for the reply Jordan, I appreciate it and have enjoyed reading your other posts as well.
I thought about the phone, but my IPhone has such unpredictable battery life I am sure it would crap out the first day of the trip and my compact camera is hardly any heavier.
The lightweight capilene for sleeping thought was keeping the bag from getting so grubby but I guess that really doesn't matter. Another thought was to have it for backup up in case the merino needed replacing for a day or two.
In your experience will merino base layers hold up , dry fast enough, etc for the entire trip?

Thanks again,
Courtney
