Extreme Cold 7A Antibacterial Polar Fleece Jacket – Heavyweight Thermal Mid-Layer for Temperatures Down to -22°F

Experience the gold standard in winter insulation with our Heavyweight 7A Antibacterial Polar Fleece Jacket. Originally engineered to withstand the brutal winters of extreme northern climates, this jacket is designed to keep you warm even when the mercury drops to -30°C (-22°F). It combines advanced textile technology with a rigorous focus on hygiene and skin safety, making it the premier choice for students, commuters, and outdoor enthusiasts who require reliable, all-day warmth and professional-grade protection.

Key Benefits

Advanced 24-Hour Heat Retention:** The specialized high-density fleece structure creates a sophisticated thermal barrier that traps body heat while preventing cold air intrusion. This "temperature-locking" technology ensures a consistent, cozy microclimate around your core for a full 24 hours of wear.

Certified 7A Antibacterial Technology:** This jacket goes beyond basic warmth by offering medical-grade hygiene. The 7A-grade antibacterial protection is lab-tested to inhibit the growth of common bacteria such as Staphylococcus aureus, E. coli, and Candida albicans, keeping the garment fresh and odor-free.

Ultra-Durable & Low Maintenance:** Built for the rigors of daily life, the premium fabric features a professional-grade anti-pilling and anti-shedding finish. It is engineered to maintain its plush texture and structural integrity without thinning or losing its shape over time.

Eco-Conscious & Skin-Safe:** Safety is paramount. This garment comes with a certified zero-formaldehyde report and utilizes eco-friendly dyeing processes. It is gentle on sensitive skin and free from the harsh chemical residues often found in mass-produced winter wear.

Superior Color Fastness:** Our high-quality reactive dyeing process ensures that the jacket remains vibrant and resists fading, even after extensive exposure to the elements and frequent laundering.

How to Use

This versatile garment is designed for multi-functional layering:

1. **As a Mid-Layer:** Zip this fleece into a compatible hardshell or windproof "storm suit" for maximum protection during blizzards or sub-zero outdoor activities.

2. **As Standalone Outerwear:** Wear it as a primary jacket during crisp autumn days or in indoor environments like classrooms and offices where extra warmth is needed.

3. **For School & Sport:** The breathable yet insulating nature of the polar fleece makes it ideal for students who transition between cold outdoor commutes and climate-controlled indoor settings.

Care & Safety

Washing:** Machine wash cold with similar colors. The 7A antibacterial properties are exceptionally durable and designed to survive rigorous cleaning cycles.

Drying:** Tumble dry on low heat or hang to dry. Avoid high-heat settings to preserve the "lock-temperature" fibers.

Storage:** Store in a dry environment. While the fabric is fade-resistant, keeping it away from prolonged direct sunlight when not in use will extend the life of the eco-friendly dyes.

Notes

"After 150 washes, the antibacterial rate remains above 90%."
