XL Kjus Reversible Warming/Cooling Gemini Jacket
Dark side out, it's a lightweight, waterproof, warming jacket. Gray side out, it's an actively cooling, stretchy windbreaker. Pack this one jacket and you're ready for golf, travel, and whatever weather comes your way.
The softest, quietest, stretchiest, lightest waterproof jacket we have ever seen. Don't let the simple good looks of the reversable Gemini Jacket fool you; this jacket is so technologically advanced that it will become the only jacket you grab every time you play golf. Worn with the dark-side facing out, the waterproof jacket absorbs 99% of ambient heat and pushes it into the jacket to keep you warm. Flip it inside out and the light side reflects 49% of ambient heat while the dark side pulls heat away from your body to cool you down. The Gemini jacket provides up to a 10.2°F / 6°C temperature differential without the use of electronics.
