1.1 Water-Repellent Down Technology: Each goose down cluster is coated with an ultra-thin waterproof film to block water molecules. It effectively prevents down clumping and uneven heat loss caused by running sweat, maintaining consistent lightweight warmth at all times.
1.2 Thermal Mechanism: 30 grams of 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 premium lightweight insulation, forming an efficient thermal barrier against frigid temperatures.
Zoned Dynamic Warmth
2.1 Windproof Warm Core Zones (Front & Back): Goose down fills the core torso and heart area for maximum heat retention. Sealed bonded fabric features distinctive dot patterns; baffle-free down-proof construction delivers water repellency and wind shielding.
2.2 Breathable Ventilation Zones (Sides, Underarms, Waist, Rear Torso): High-stretch fleece knit balances warmth and airflow to keep you comfortable post-sweat. Inner fine fleece locks heat and repels cold dampness.
2.3 Sleeve Windproof Zones: Woven panels cover upper arms for wind protection; high-stretch fleece knit on forearms ensures unrestricted movement.
Enhanced Ventilation for Men
Hidden mesh gussets on front and rear panels boost internal air circulation during workouts to expel excess heat and avoid overheating and sweat buildup.
