With the weather turning cold but the call of the outdoors irresistible, the Tephra Reflect Vest makes sure you aren't left shivering. Hydrodown®, with a 600-fill power content, provides insulation without sacrificing weight. You'll find the windproof Pertex® Quantum shell also prevents ice-cold winds from robbing precious body heat. Extra warmth is also built-in via REFLECT Technology. This super-light and reflective mesh works to reflect heat back to your core. In fact, it keeps you up to 20% warmer when compared to a vest without this tech. Last, but by no men's least, the Nikwax® treatment provides a barrier against wetter weather conditions. This is a vest ready for any outdoor escapade.
