[pct-l] Sleeping bag help, please

[Kit Hepburn]

Hello,

I am planning to join my thru-hiking boyfriend for a couple of weeks in
Northern California, hopefully the section that passes through Mount Lassen
National Park.

I'm totally undecided as to what I will need for a sleeping bag.  I tend to
sleep cold, and last weekend when camping in Keno, Yukon, I was miserable
in my current synthetic bag that is rated to 32F.  I think the temperature
was close to freezing that night (I was close to freezing, at any rate).  I
am contemplating investing in a good down bag that would be more suitable
to average Yukon conditions but also useful for my PCT section hike--maybe
a 15 F (-10 C) bag.  Would something like this be total overkill for
Northern California in July, or just right for a cold sleeper?

Please weigh in!  I really enjoy reading all the pctl emails, and am very
excited to get to experience a section of the trail.  Any advice will be
greatly appreciated.

Cheers,

K.
