How to Choose a Synthetic Jacket
Synthetic insulation can be found in technical mid-layers, stand-alone jackets, and puffy parkas. Unlike down fill, synthetic insulation will insulate even when wet. It's also less expensive. For hanging out on belay or cruising town in the cold all you need is warmth. If you're skiing, backpacking, or climbing, weight and fit become more important in choosing an insulated jacket.
