Our ThemoNeutral down mid-layers features FORLOH’s Perf-Weld® technology that ensures exceptional breathability through micro-perforations in the Sonic Weld construction. Perf-Weld™ lets excess heat out when physical demands cause body temperature to rise. This keeps your body temperature neutral and you stay comfortable and drier, all day long.
