Ive been hearing a lot about merino wool base layers, such as Icebreaker. What are your thoughts on this fabric? Is it a suitable alternative to synthetic fleece layers for a mountain climb such as Kilimanjaro? Iain Solihull, UK

But the wool worn today is far better than those rare Air Force trousers. Icebreaker (www.icebreaker.com) products, for instance, are made from merino wool, which is exceptionally soft and itch-free. Plus, there are little natural pores in the fiber that help add insulation, while also allowing wool to absorb a great deal of moisture before it feels wet. Merino wool also is durable, and, like the pants I recall so well, its comfortable across a wider temperature range than synthetics.
I have three Icebreaker shirts of various weights and sleeve lengths. I use them mainly as a base layer for winter bicycling, skiing, and climbing high peaks such as Rainier. Ibex (www.ibexwear.com) and SmartWool (www.smartwool.com) also make excellent wool-based apparel. For warm weather I still tend to prefer Patagonias Silkweight Capilene (www.patagonia.com) and shirts made from CoolMax (available at stores such as L.L. Bean and REI).
Anyway, when wearing a wool base layer, I need about half the total clothing of other people Im with. And I dont need to constantly adjust my layers; I can go with a base layer and maybe a light shell.
The one downside to woolen clothing is its price. Icebreakers very useful Skin 200 Mondo Zipa long-sleeve shirt in a light wool materialis $68. Other pieces are more. That compares to $30 to $40 for most synthetics. But, is it worth it? Overall, Im inclined to say yes. That goes for your Kilimanjaro climb as well. You dont need to pack a half-dozen woolen pieces, but two or threemaybe a lightweight tee and a mid-weight, long-sleeve shirt and bottoms would certainly be useful.
