The sleeping bag is filled with 150gsm polyester wadding. Its outer fabric is 190T embossed nylon W/R-Cire, and the lining is 190T polyester pongee Cire. The product is therefore a synthetic-filled sleeping bag, even though the catalog name includes “Synthetic cotton.” Buyers specifying natural cotton should distinguish that requirement from this model's polyester insulation and lining.

The sleeping bag measures 215 × 85 × 50 cm and is intended for adults. Its standard length is suitable for people up to 1.8 m tall. For a hiking program, compare that length with the tallest intended user before ordering. The mummy shape narrows toward the foot area, so the buyer should also allow for the sleeper's preferred clothing layers and movement.

Yes, the model is designed for outdoor hiking and has waterproof protection. The nylon shell uses W/R-Cire fabric, and the product is described for wet outdoor conditions. Waterproof protection does not replace site planning: use a dry sleeping platform and shelter, and keep the packed bag protected during transport.

The listed comfortable temperature scale is 15°C to 5°C, with a cold-weather classification for spring and autumn use. Buyers should match the sleeping bag to the expected overnight conditions, clothing, shelter, and individual comfort needs. This temperature range should not be treated as a guarantee for every user or every campsite.

The sleeping bag weighs 1.2 kg and is supplied in an OPP bag. Its single-package size is 45 × 28 × 28 cm. Those figures help distributors estimate packed volume and shipment handling, while hikers can use them to check whether the packed size fits their planned gear space.
