What type of jacket to buy to keep yourself warm this winter
The Weather Channel • • technology
Key Points:
- The warmth of a winter jacket primarily comes from its insulation fill trapping still air, not from the outer fabric or thickness, with loft (fluffiness) being a key measure of its heat retention ability.
- A tightly woven outer shell is essential to block wind, which can quickly strip away the warm air trapped by the insulation, making the jacket effective outdoors.
- Jackets must balance waterproofing and breathability to keep you dry without trapping sweat, as moisture inside the jacket compromises insulation and warmth.
- Newer jacket designs incorporate reflective linings that bounce body heat back to the wearer, enhancing warmth without sacrificing breathability by using patterns or dots instead of full coverage.
- The best winter jackets combine trapped air insulation, wind-blocking shells, and breathable waterproof membranes, with modern materials enabling lighter, thinner, and warmer layers than in the past.
