The Spiro Fitness Zero Gravity Jacket redefines lightweight layering through innovative engineering. Featuring polyester faux down padding with nylon lining, it delivers exceptional warmth without the weight—virtually weightless yet highly effective as an ideal mid-layer garment for fluctuating temperatures. The showerproof, breathable construction protects against light precipitation whilst maintaining optimal ventilation, essential for active pursuits in variable weather. Quick-dry properties ensure rapid moisture management, keeping you comfortable during intense training or outdoor activities. The integral hood with super stretch construction provides adjustable weather protection without restricting movement, whilst super stretch sleeves accommodate dynamic arm movements through training and everyday activities. Quilted body panels reinforce insulation where you need it most, concentrating warmth efficiently. The full-length zip enables precise ventilation control and quick transitions between activity levels. Articulated sleeves follow your body's natural movement patterns, eliminating restrictive pressure points during dynamic exercises. Invisible front zip pockets provide secure storage without disrupting the jacket's streamlined aesthetic. Bound hood, cuffs, and hem reinforce high-stress areas whilst creating a polished finish. Thumbholes on cuffs anchor the sleeves during movement and extend warmth coverage. Reflective detail enhances visibility during low-light training sessions. Tag-free construction ensures all-day comfort. Whether you're training outdoors, commuting, or layering for variable conditions, this zero-gravity jacket combines innovative technology with practical performance.
