Beneunder Women’s Air-Down Lightweight Outdoor Jacket - CL004

Experience the next generation of outdoor warmth with the Beneunder Women’s Air-Down Jacket. Designed for the modern adventurer who demands performance without the bulk, this jacket utilizes proprietary "Air-Down" technology to provide superior insulation in a sleek, lightweight profile. Whether you are navigating a damp morning hike or a windy city commute, the CL004 offers a sophisticated balance of "Medium Warmth" and high-tech weather resistance.

Key Benefits

Advanced Air-Down Technology:** Unlike traditional down that loses its loft when wet, our proprietary Air Bloom material maintains 95% of its fluffiness even in high-humidity environments. This ensures consistent warmth regardless of the weather.

Triple-Layer Heat Locking:** Engineered with a specialized three-layer system—comprising a heat-generating layer, an insulation layer, and a temperature-locking layer—to trap body heat effectively.

Volcanic Rock Particle Infusion:** The fabric is integrated with three-dimensional volcanic rock particles that can boost temperature retention by up to 6.9°C, providing an extra shield against the chill.

Weather-Ready Protection:** Stay dry and comfortable with Grade 4–5 water and stain repellency. The high-density construction also offers professional-grade windproofing (23.4mm/s) to block out biting gusts.

Ultra-Light & Durable:** Weighing only approximately 540g and measuring just 2.5cm in thickness, this jacket eliminates the "puffy" silhouette. Despite its lightness, it is built to last with a high abrasion resistance rating of over 18,000 rubs.

How to Use

This jacket is optimized for "Lightweight Outdoor" activities and daily transitions. For best results:

1. **Layering:** Wear as a standalone outer layer in temperatures between 5°C and 15°C. For colder conditions, its slim 2.5cm profile makes it an excellent mid-layer beneath a heavy parka.

2. **Activity:** Ideal for hiking, trekking, or urban commuting where mobility is essential. The breathable 10L/m² fabric ensures you stay warm without overheating during physical exertion.

Care & Safety

Storage:** To maintain the structural integrity of the Air-Down fibers, store the jacket in a dry, ventilated area. Avoid long-term compression in small bags to preserve the maximum loft.

Maintenance:** While the fabric is highly wear-resistant (18,000+ rubs), avoid contact with sharp jagged edges to maintain the integrity of the water-repellent coating.

Cleaning:** Use mild detergents to preserve the specialized volcanic rock particle infusion and the 3-layer locking system.

Notes

The CL004 is specifically engineered to ensure "95% loft retention in high humidity environments," making it a more reliable choice than traditional down for coastal or rainy climates.
