[pct-l] water carrying capacity / frameless backpacks

[Ellen Shopes]

A basic rule that works for many people in the desert is to plan about 1 
liter per hour of hard exertion.  This applies to temperatures in excess of 
about 80-85 degrees.
Another good way to get an idea is to weigh yourself before and after 
exercise, to gage how my sweat/water loss you accrue.  The record (measured 
in a physiology lab with a guy maximally exercising in a suit designed to 
capture all his sweat)  was right at 2 liters/hour.  The subject was not 
able to sustain this level of exertion for very long.

I would highly recommend that you do some desert hiking and get a sense for
how much water you need to stay hydrated. I found hiking in Grand Canyon
that when its really, really hot, I need up to 3 liters in the first half
of the day and 4 in the second half. I adjust down from there, depending on
anticipated temperature. Others seem to get by with less.

I have seen the effects of dehydration on a fellow hiker, and the situation
can become serious very quickly. As a result, I usually err on the side of
carrying too much water.

Hello Lenny,

I've sectioned-hiked from Anza to near Mather Pass with a frameless Golite
(I forget the name of the model) that weighs about one pound.  I've carried
40+ pounds in the desert, including eight liters of water in a couple of
stretches (four two-liter soda bottles), with no problem.  (In retospect, I
could have got by with six liters; if you hike faster than my 12-15 miles
per day, you might need even less, but IMO it's always best to carry a
little more than you think you'll need.)  Also, a medium-sized bear
cannister fits perfectly (horizontally) in the bottom.  In sum, I reommend
it without hesitation.

Hello,
I was wondering about water in Southern California, and specifically how
much carrying capacity is recommended.?

How did it feel after a resupply, carrying close to 30 lbs with the little
Golite Breeze??  <snip>
