[pct-l] 30 degree bag on the JMT in September?

[dude at fastmail.ca (dude)]

It depends on several things:
* do you tend to sleep "warm" or "cold"?
* will you be using a tent or tarp? (if a tent, what kind and will 
someone else be in the tent with you?)
* is the bag clean and fluffy and still as warm as it was when new?
* some bags tend to perform better or worse than rated, do you have any 
experience with yours?
* do you have extra clothes you can wear to sleep if you get cold? (ie: 
down jacket, fleece, long underwear)

Having addressed all those issues, I have been on the JMT in September 
twice(98 and 2001) and both times it was relatively warm: high 20's or 
low 30's at night.  Most of the JMT is at higher altitudes, so only 
getting down to the 30's is really warm.  Both times on the JMT, I used 
a two-person tent and slept in the tent with another person, which 
helps warm up the tent.  The last time I was on the JMT, I used only a 
small down blanket that I had custom made at www.nunatakusa.com that 
weighs only 14oz.  The night that I was the coldest was the night at 
VVR in the hiker's tent.  The other nights I was warmer, and one of 
those was just out in the open with no tent.


peace,
dude
