Well, Abi, here is what I want you to do. I want you to take off your shoes and socks (I assume you are not wearing gloves). Then, hold your feet and hands out in front of you, where you can see them. Now, for each digit, assign a dollar value. Take your time. Whats that pinkie worth? $100? A big toe? $250? Think hard.
Dont think this exercise oddyou are doing it right now. You are hoping to save a few hundred dollars on gear. And in doing so, you are weighing those dollars against body parts. Do you think I am kidding? I have been to Denali, summiting in two weeks in very benign conditions. And it was so fricking cold my internal thermostat was red-lined for two full weeks after I got back to Seattle. You live in San Francisco? You cant even imagine, young lady.
So, no, your Sub Zerowhile a fine pieceis not adequate. Layering a down sweater under it is only a marginal gain (although the down sweater might be a great thing when in the tent). You need a full expedition parka. At least Feathered Friends Icefall Parka ($569). The Rock & Ice ($779) is even betterask me, and you can rent mine, which I bought for the Denali climb and never regretted. Really, nobody makes anything comparable.
And if your feet get cold, then get out the credit card again. At the very least, you need a pair ofScarpa Invernos ($319), an excellent cold-weather boot at a good price. Add a few pairs of expedition-grade socks (SmartWool Expeditions for $20 a pair) andOutdoor Researchs Brooks Ranger Overboots ($160).
That setup will work for you in the Himalayas. Its not a real Lower-48 setupyou have to size the boots for high-altitude foot-swelling, and layered socks.
I dunno what you have for a sleeping bag, but a minimum of a -20 bag is mandatory.Marmots CWM Membrain bag (-40, $679) is the ticket. And two padsa self-inflating pad, and a closed-cell foam pad. Trust me on this.
No, it isnt cheap. But go ahead, start putting dollar figures on those digits.
