I am planning on hiking the Sierra High Route this summer from August 15-September 10. It looks like it will take me about 22 days on-trail, with resupplies in Bishop, VVR and Tuolumne. I will be hiking solo. I've never been on a trip longer than a week, but I have lots of mountaineering experience in the Sierras so I think the technical portions of the route should be in my comfort zone.
I expect that the majority of the days will be in the 60s-70s with lows around 30F most nights, though I will often be sleeping around 10,000' and I expect a handful of nights it will get down to 20F. My main concern is that my Summerlite won't be warm enough. I can bring an REI Sub Kilo instead, with 4 more ounces of down, but at a weight penalty of 10oz. Let me know what you think.
I am also considering swapping the NeoAir for a 72" Ridgerest Solite for durability issues. The weight is the same, but I am worried about the Ridgerest being bulky for scrambling and I don't find it very comfortable.
I will be carrying 7 days/10.5 lbs of food at the most for a total pack weight of about 26 lbs.
Sorry, don't have the weights for my worn clothing, but here is a list:
Patagonia Capilene 1 L/S tee
Patagonia Capilene 2 boxers
REI nylon sun hat
Arcteryx Palisade pants
Smartwool PhD running socks
Scarpa Epic approach/trail running shoes
