Here is a jacket that helps you stay as warm as you want outdoors. Every NuDown garment relies on NuTech technology to enable you to adjust your ideal temperature using air. The more air you pump in, the more air is trapped between yourself and the garment. The inner-air is warmed by your body. You can release air to cool down or even rely on Argon gas to triple the insulation power (thanks to Argon’s higher molecular density).
