Lhotse - Equipment

Here is the equipment checklist it was suggested Lorenzo should take.

Lightweight polypro, capalene, or 100wt. Polartech, stretch fabric is best- top and bottom for layering, plus an extra set. 2 sets.
Mid to exp weight polypro, capalene, or 100 wt. Polar tech, stretch fabric is best - top and bottom for layering. 2 sets.
Pile (fleece) coat- 200 or 300 weight polar tech
Primaloft or light down pants or Pile (fleece) pants 200 weight polar tech, full side zips are best (can be lighter pile)
Expedition Down parka and down pants with hood expedition weight down suit is ok also! Extra Down Parka for Base Camp.
Expedition Down Suit, You can get these in Kathmandu but the North Face ones are lighter (and a lot more expensive!)
Gortex jacket and pants or full Gortex suit (best), the lighter weight Gortex is best, side zips on the pants! Wild Things makes a very good lite suit!
3 pair light weight polypro sock liners
5 pair heavy wool or polypro socks
1 pair mid weight to heavy weight poly pro gloves, wind stopper material is highly recommended!
Expedition insulated gloves with shells. Thick Alpine Glove system.
Expedition down, prima loft or pile mittens with shells (super thick), OR, Marmot, Mt. Hardware, North Face brands are all good! Lightweight!
Balaclava or thick ski hat with neck gaiter, neoprene face mask for face protection
Baseball cap or similar sun hat
Good pair ski goggles with UV protection, good for high winds! New, with darker lenses.
Sunglasses with side shields, quality name brand glacier glasses are important! (UV protection/dark). Julbo, Cebe
Everest One Sports or the new La Sportivas Olympus Mons are the best and warmest boots! Available for a reasonable price in Nepal and Europe. Double plastic climbing boots are basically not warm enough unless you use over boots and then they are heavy. Make sure they are not tight, that you can get your finger behind your heel with all socks on and insoles in! Loose is better than tight.
A second pair of lighter single boots for later season BC to C2 trips. Crampon compatible leather.
Regular Shorter gaiters and over boots (highly recommended) for higher up, neoprene over boots are best. Not necessary for One Sports.
Hiking shoes (broken in!), high tops, it's a long trek in!
Sleeping bag rated to -20 plus a sleeping bag rated to -40! Compressor stuff sacks for bags! Down for the high bag. You can use a new-20 bag for up high, but you will be a bit on the cold side. The advantage is its lighter, you will be carrying this. This is what the guides do.
Sleeping pads 1 long regular or guidelite Thermarest for up high on the hill, plus one Super fat, wide, long Camp Rest LE for BC or equivalent.
