Down Underquilt for Hammock – Selva 300 | Cumulus

Description

Cumulus Selva 300 – Premium Down Underquilt for Hammock Camping

The Selva 300 is a high-quality, oval-shaped down underquilt designed for hammock users who want reliable insulation during cooler seasons. Intended for two-season use, this underquilt offers a superb balance of warmth, weight, and packability. It can also serve as a light sleeping bag or top quilt when placed inside the hammock. Thanks to its optimized construction and premium materials, the Selva 300 guarantees comfort, even when the temperatures begin to dip.

Advanced Design for Maximum Thermal Efficiency

The H-shaped chamber structure combined with a differential cut ensures the down stays evenly distributed while minimizing cold spots. Compared to its lighter sibling, the Selva 120, this model provides significantly more insulation, making it suitable for more demanding conditions. The 10 longitudinal down-filled chambers prevent down shifting and sagging, maintaining loft and warmth throughout the night.

The oval shape is not only ergonomic but also ensures quick and secure attachment to a wide variety of hammocks. The underquilt spans the full length of a standard hammock, offering complete thermal protection from head to toe.

Premium Materials Inside and Out

Selva 300 is crafted from Pertex® Quantum DWR, a technical fabric known for its lightweight, durable, and down-proof properties. Both the outer and inner layers weigh just 29 g/m², contributing to the quilt’s outstanding warmth-to-weight ratio.

The insulation comes from ethically sourced Polish goose down, boasting a fill power of 850 cuin, ensuring exceptional compressibility and thermal performance even in low temperatures.

Smart Suspension and Fine-Tuned Fit

Ease of use is a hallmark of the Selva 300. Its shock-cord-based suspension system includes adjustable cords at both short ends, secured with cord locks, allowing you to fine-tune tension and positioning for a draft-free setup. The system is compatible with all lightweight camping hammocks.

Hanging loops are integrated for convenient storage and drying after use.

Compact and Lightweight for Efficient Packing

Despite its warmth, the Selva 300 remains light and compact, making it an ideal choice for backpackers, thru-hikers, and minimalist campers. It compresses down into a 4-liter stuff sack, measuring approximately 22 × 16 cm.

Whether you’re headed for a spring trek, a breezy summer night in the forest, or autumn adventures, Selva 300 is the perfect companion to ensure a warm, restful sleep in your hammock.
