Women's Heat-Seal 750-Fill Water-Repellent Goose Down Running Vest

750 Fill Power 95% Water-Repellent Goose Down

 1.1 Water-Repellent Technology: Ultra-thin waterproof film coats each down cluster to repel water molecules, preventing clumping and uneven insulation caused by sweat during runs, maintaining consistent lightweight warmth at all times.

 1.2 Thermal Performance Principle: 30g white goose down occupies 750 cubic inches of volume. Higher fill power means larger, fuller down clusters that trap more stationary air. 750 high fill power delivers outstanding lightweight insulation, forming an efficient thermal barrier against frigid temperatures.

Zoned Dynamic Warmth

2.1 Windproof Front Thermal Zones: Core torso and heart area fully filled with goose down. Sealed bonded fabric with distinctive dot print; baffle-free down-proof construction delivers water repellency and wind shielding.

 2.2 Breathable Side & Rear Zones (Underarms, Waist, Rear Torso): High-stretch fleece knit balances warmth and ventilation for post-sweat comfort. Fine inner fleece retains heat and blocks cold dampness.

 Enhanced Ventilation for Men

Hidden mesh gussets on front and rear panels boost internal air circulation during workouts to vent excess heat and avoid overheating and sweat buildup.
