The Columbia Grand TrekTM is a classic Down Jacket, but with modern technology and construction to make it better than ever. For one, it features Heat Shield stitchless baffling, so the 650 fill-power down stays in place, and there are no holes in the fabric. Heat Shield helps the Jacket maintain a higher level of windproof and waterproof comfort than standard down jackets.
Omni-Tech 100% waterproof/breathable technology keeps water out while allowing sweat vapor inside to escape—so you stay cooler and more comfortable. The Omni-Heat thermal reflective lining traps your body heat to keep you warm.
