When the forecast calls for cold temperatures and plenty of powder, we zip into the 686 Whisper Insulated Jacket and head for the mountains. The infiLOFT synthetic insulation traps precious warmth close to our core, while the helmet-compatible hood shields us from icy blasts. The infiDRY membrane keeps falling flakes from soaking into our baselayers, and the two large Air-Flo vents on the chest give us complete control over ventilation.
