The Columbia Heat Elite Lite jacket is built to withstand almost any weather conditions with warmth but not the bulk. With Omni-Heat® technology the thermal interior silver dots reflect and retain your natural body heat to keep you 20% warmer than a regular lining. These silver dots are bonded directly to the interior fabric whichs eliminates the added bulk of a separate lining. Omni-Shield® advanced repellency treatment repels rain and stains. Articulated elbows and two-way comfort stretch provide added comfort and ease of motion to your daily activities. Long, vertical pockets are strategically placed to provide an alternate location for warming hands when backpack straps would otherwise block entry to the hand pockets.
