curious what pack you used that you were dissatisfied w/? if you had to do it again, what pack would you chose?
< plan on doing the JMT summer after next
OK, I'm looking at it right now... It says Osprey Stratos 40. Since I have the Large sized one, it holds 42L, not the nominal 40 of its model name.
The mfg. rates it to hold 35 lbs. I didn't weigh my pack, because I knew I was exceeding the weight rating by 10 or 15 lbs (denial? If you don't formally know how overloaded it is, the shoulder straps can't rip out???

The thing about the JMT is this, plans change and situations change. You will definately want to pop out of the JMT at Devil's Postpile Nat'l Monument and take the $7 bus from the ranger station out to the free shuttle bus located at the giant Mammoth idol near the ski lifts. This takes you into town for resupply, whether at Whole Paycheck (Whole Earth Foods) or more likely, Vons. Food resupply at Vons was ever so slightly limited in selection with slightly high tourist town prices, but pay them anyhow. This is definately once in a lifetime type stuff, and not the time nor place to be too cheapskatish.
Pack recommendation: Cannot tell you an exact model. What I can say, is walk into an REI and look at their $200+ 60Liter packs. All of REI's stuff is quality gear.
Get fitted to a quality pack there, and you'll be in good shape.
Other gear I used and recommend for this jaunt:
-Snow Peak Gigapower butane stove. Performed excellent. I used 4x 220g cannisters for the entire trip
-Mountain Hardware 30degree down bag. Don't bring less bag. Storms make everything colder for a couple days, once a week.
-Trek 700 titanium cup. Excellent for coffee & Mountain House
-Mountain House -- avoid the Jamaican entree. hated it with a passion. If you bring freezedried, Tabasco is mandatory. Their Mexican and Chinese and Lasagna ones were very good.
-OR goretex bivy bag.
-those addictive goldfish crackers in the quart rectangular paper sack.
-Bacardi Gold
-cheap lexan teaspoon
-SAK Recruit
-Noxzema(sp?) SPF 70 sunscreen. Buy fresh at the last minute. DO NOT bring last years sunscreen.
-tiny bottle of %100 DEET "Jungle Juice"
-granola bars
-Cliff Bars
-instant OreIda mashed potatos were surprisingly good.
-tortillas+cheese+summer sausage + Tabasco = Excellent fake pizza
I'm 6' and 170lbs. On a diet of 2x 600 calory Mountain House freezedried's plus 4 Cliff Bars plus 2x teabags and an Emergen-C a day, I did OK. This was definately the minimum of food to ALMOST maintain your weight. I lost 6 lbs over the 15 days of the trip.
Bring the smallest, lighted fishing pole you've got. All the prestige high rent fishing is in the first third of the trip, between Tuolumne Meadows and Edison Lake. The absolutely first rate Golden Trout fishing is only found at Sally Keyes lake.
Make damn sure you stop here, and fish Sally Keyes. They are huge (for goldens) and will bite easily on anything. I considered all the other lakes as definately less interesting.
The trail is made of sharp granite frags and moon dust. Getting clothese and body clean in a cold environment was a challenge, to put it mildly. Bring a razor, and shave in your coffee cup once every 3 days. The peeps who didn't, looked like bums! Wear shoes that are hard enough on the bottom that you can walk on jagged granite fragments with impunity. My Vasque trail runners were barely adequate, in this regard.
