Cozy in the cold.

* Winter, wonderful winter! The oppressive summer months are nothing more than a bad memory now. Anything even approaching 50[degrees] we consider a heat wave. The next 12 weeks are to be treasured tike no other time of the year. Every flake of snow, every last icicle, every frigid blast of bone-chilling wind, yes, even every dirty pile of ankle-deep slush--at least as far as we're concerned--is heaven sent.

However, if you're going to take on Old Man Winter--especially the wind, wet, and cold--you had best be dressed properly. That means in layers, and the first layer should be thermal. A number of quality labels--many under the Sara Lee-J.E. Morgan Knitting Mills, Inc., Tamaqua, Pa., umbrella-are out there, including Hanes, Duofold, Arctex, and Morgan Mills. Hanes provides the thermals we all probably know best, the 65% cotton/35% polyester waffle knit fabric with rib cuffs at the wrists and ankles. The reinforced seam construction gives both the crew neck top and ankle-length pants ($6.99 each) longer-lasting durability. (The real breakthrough at Hanes, though, is its no-tag white cotton undershirts, which cost $10 for a three-pack. For years, we've been ripping, cutting, and pulling those annoying, skin-irritating tags from all our garments. No longer.)

Duofold, meanwhile, thanks to its four-way stretch Varitherm thermals, is the perfect base layer for the winter athlete. (In our case, that means ice hockey, jogging, and, when the elements allow, tennis.) It's no wonder that the Team USA luge squad, National Ski Patrol, and Professional Ski Instructors of America all endorse Duofold. The fabrics utilize Varitherm fibers that are engineered with a hollow core, which moves water vapor out, but traps air in to create a highly effective barrier. To further ensure perfect body temperature control, the Varitherm line comes in five variations: single-layer lightweight, stretch single-layer mid-weight, two-layer heavyweight, stretch single-layer heavyweight, and stretch two-layer expedition weight. Each individual--and the outside climate conditions--is different, but the idea is for a lighter and thinner base the more active you are, and a heavier, thicker base when you're out in the extreme cold, but not too active. We heat up quickly and enjoy the frigid air, so the single-layer versions (around $25 each for tops and bottoms) are better suited for us than the two-layer sets (around $35 each for tops and bottoms).

Now, if you really want to...
