I've had my Trail Lite Designs Cloud Kilt for a little while now. I'll just say this: get one! The ventilation alone is sweet, the lightness in the pack is sweet, sturdy & excellent craftsmanship, and the black color gives you some modest privacy for the privates when trying to do laundry & don't have extras of things to wash in.
Some missings: (?)
- bug headnet for Sierras
- wind jacket
- Bowie knife (ok, kidding!)
- headwear (for sun protection or warmth) and also for sleeping
- insulation piece (like Nano Puff, etc. )
I highly recommend the Patagucci R1 Hoody. Highly highly. I love, nay, am in love with mine. (my PCT list is at http://thf2.wordpress.com/pct-gear-list/ ).
25 mile days straight off for the PCT is ambitious from what I have heard. Most start off 12-15 mile days for a week or so, then acclimate to higher daily miles. But hey, if you're 17-18, maybe you can slam it! :) I'm starting the PCT in late April '11, see you out there!
