I climbing Mount Kilimanjaro in August. I have been skiing before but never in sub-zero conditions. Will two layers of long underwear under two layers of fleece and a waterproof, windproof shell jacket be enough to handle the cold at over 19,000 feet? Or do I really need to get down or something like it? Steve Moorpark, California

I think you're close to having what you need, but you might want to beef up your cold-weather kit. If I were heading to Kili, I'd start with a layer of mid-weight long underwear, such as REI's Midweight MTS crew top and bottom ($30 each; www.rei.com). Next, a layer of good fleece, around 200 or 300 weight, such as Mountain Hardwear's Monkey Man Jacket ($115; www.mountainhardwear.com). And a good waterproof-breathable shelltop and bottom, which you indicate you already have. Starting from scratch, I'd probably go with L.L. Bean's Mountain Guide Gore-Tex XCR Jacket ($279; www.llbean.com), then Marmot's PreCip Pants ($70; www.marmot.com), although the pants might end up being "sacrificial" given the sometimes rough conditions on Kilimanjaro. But they'll work fine.
I am inclined to suggest you pack along a light down-like piece. It doesn't have to be terribly exoticPatagonia's Micro Puff Pullover ($145; www.patagonia.com) would be fine. But it'll add an excellent layer in case it's both cold and windy when you summit. It's also a useful ski-layering piece for when you're back home.
Of course, a good selection of warm gloves and hats also is essential.
Still, cold aside, the main thing will be your reaction to altitude. Don't rush the trip and take time to acclimate. Good luck!
