Imagine a sleeping bag that combines advanced technology with sustainability, providing comfort in cold weather while being lightweight and easy to carry. Here's why the ATEPA ELEMENTS 450 Coldmaster™ Down Mummy Sleeping Bag is perfect for your next adventure:
3D Box Quilting: Expertly designed to optimize down fluffiness and thermal insulation. The three-dimensional structure ensures maximum warmth by forming a breathable cavity between layers, enhancing insulation while reducing overall weight.
Unique Down Blend: Filled with Coldmaster™ Down, 450 grams of high-performance down and cotton blend—55% premium 90/10 down and 45% ball cotton. This combination offers the warmth of down while minimizing moisture absorption, ensuring you stay cozy in all conditions.
Durable Yet Lightweight Fabric: Made with 20D nylon and 15D nylon that is both tear-resistant and water-repellent. This high-density fabric reduces the weight of the sleeping bag without sacrificing durability and is easy to clean.
Perfect Fit: Sized at 220×80-55 cm (86.6×31.5-21.7 inches), the bag fits most standard sleeping pads, providing a snug, insulated experience while reducing cold spots.
Comfort-Oriented Design: Features include a 3D foot compartment that conforms to your body, a drawstring hood for warmth, and arc quilting that reduces the movement of filling, preventing cold spots even when you sleep on your side.
Eco-Friendly & Sustainable: The sleeping bag uses renewable ball cotton, a recycled material that is environmentally friendly. The unique down mix is designed for high resilience, lightweight comfort, and superior warmth in tough outdoor conditions.
Adjustable Comfort Levels: With a comfort rating of 6°C (42.8°F), a limit temperature of 1°C (33.8°F), and an extreme rating of -14°C (6.8°F), this sleeping bag offers versatile performance across a range of temperatures.
