Those would be YOUR burly legs, Jason. Mine are slim and trim. Quite fetching, actually. Mrs. Gear says so.
November to March is the cold time of the year, so I’d layer up. Thinking a base layerwool, no question. Patagonia’s Men’s Merino Wool 3 bottoms ($90) are ideal. A little more than mid-weight bottoms, so they’ll be good for cool to cold conditions. Excellent thermal regulationeven if wet you’ll be pretty warm.
I’m okay with synthetics, as well. They’re a little lighter and dry more quickly. REI makes a nice heavyweight bottomthe Heavyweight MTS Bottomfor $35 (on sale at press time for under $20). So price is a factor as well. But I do like wool.
Often, you’ll be able to just wear a pair of shorts over the bottoms. But for the wet of winter, you’ll want some sort of shell over the bottoms. The very basic setup would include Marmot’s Full Zip Precip Pants ($90). More than adequate pants, and hard to beat at the price. Best if you’re not doing a lot of real aerobic stuff.
Nicer but more expensive? Mountain Hardwear’s Typhoon Pants ($180). Made with Gore-Tex Paclite, a very light, breathable, rainproof material. Fabulous over a nice pair of wool bottoms.
