I\'ve been aware of Columbia\'s line of jackets with its touted heat insulating technologyI\'m just a skeptical about its effectiveness and how it compares to the more well-known, tried and true, and more affordable wool fiber/fabricI\'ve always been told that wool is the quot;go-toquot; fabric of choice for winter clothingNow, I don\'t live in the coldest areas in the U.SBut, it\'s still darn cold here in California for my personal standardsIs Omni-Heat Reflective Technology meant for areas like Alaska, Maine, Canada, etc? Can anyone shed light on this? Please provide any good source if availableI don\'t want to take a Yahoo! Answer response by face valueI\'d like to know where you get your information fromThank you.The reason for going to wool is because it breathesreflective clothes are warmer because they have a sheet of
aluminum foil built in but they don\'t breathe and you get all wet from sweatThey are made for much colder places than Ca Put on a sweat shirt, cover it with tin foil then put on a jacket over it.Other related question
