Naturehike CW700 CNK2450WS048 Natural Down Sleeping Bag, Size M — Overview and Features

Naturehike CW700 — a warm and functional yellow-gray sleeping bag designed for camping and hiking in cold weather. The model is intended for use in winter and cold off-season, ensuring comfortable sleep at low temperatures. Manufacturer: Naturehike. Product type: Camping & Tourism > Tourism > Sleeping Bags.

The CW700 guarantees protection from hypothermia in a temperature range from -1.7°C (comfort) to -7.9°C (maximum), with an extreme temperature according to the scale of -26.2°C. This temperature rating allows for planning trips even on harsher nights when reliable insulation is crucial.

The outer material of the sleeping bag is water-repellent 20D nylon, which is durable and wear-resistant, silent, and helps repel water and dirt. The lining is made of soft, pleasant-to-the-touch nylon, which maintains a comfortable microclimatic atmosphere inside the sleeping bag and wicks away excess moisture from the body.

The insulation is duck down with a density of 700 g/m² and a Fill Power rating of 650FP. This combination ensures effective heat retention even in variable weather conditions, and the quilted down distribution structure prevents the formation of cold spots.

Design and functional details:

• The hood is width-adjustable, allowing for tight insulation of the head from drafts.
• A flat base with an expanded footbox provides freedom of movement and avoids a cramped feeling.
• The YKK zipper with two sliders allows for ventilation adjustment — partial unzipping from the top or bottom prevents overheating; full unzipping transforms the sleeping bag into a blanket or a soft mattress.
• A Velcro insert near the zipper protects against zipper snagging and hair getting caught in the fastener.

Dimensions and weight: when unfolded, the sleeping bag measures 210 x 75 cm, corresponding to size M; after packing, the volume is Ø20 x 42 cm, and the product weight is 1074 g. Official manufacturer's warranty — 1 year.
