Lightweight and practical gear that could save your life

The most common mishap to befall hikers in the Southern Appalachians is getting lost, which isn’t necessarily life-threatening if you’re prepared. Here are five common sense items—that weigh less than a pound combined—to keep in your pack on every outing.

THE WRINGER Columbia Heat Elite Jacket Columbia claims its Omni Heat jackets will keep you 20 percent warmer than similar jackets without the lining. It sounds gimmicky, so we put it to the test in sub-freezing adventures.

Columbia’s new Omni Heat technology combines 60 grams of synthetic insulation with a liner that’s covered with tiny mirrors designed to reflect and trap your body heat. The Heat Elite has a sleek, athletic cut, but it claims the warmth of a thicker parka. It’s an attractive combination for people who like the warmth, but not the bulk, of a puffy.

Columbia is basically repurposing the old emergency blanket technology developed by NASA in the 60s, which has been shown to trap 90 percent of your body heat using the same reflective concept. To avoid moisture buildup, Columbia placed a wicking material between the reflective dots in order to release some of the body heat and moisture you create when skiing or hiking in the cold.
