The outer is made of DryVent™, a waterproof but breathable fabric that is seam sealed so even wind-driven rain won't permeate. An essential element to any serious jacket is the hood and the hood of the Quest is made of the same waterproof fabric as the rest. It's also adjustable for a close fit. The synthetic Heatseeker™ insulation keeps your hard-earned warmth inside, maintaining your core body temperature.
It's always worth having a warm mid layer ready for when the weather turns extra chilly, something to wear under your Quest, or as a pullover indoors before the heating kicks in.
