A high-quality down jacket can keep you comfortable during everything from backyard social gatherings to winter snowshoe adventures. To help us choose our favorites, 10 testers romped across every corner of New Hampshire’s iconic Presidential Range and throughout the Pacific Northwest in 57 insulated jackets, covering more than 300 miles. We took on conditions that ranged from frosty to wet to mild.
