This is an emergency evacuation sleeping bag type bedding made with Tyvek® Silver, featuring high thermal insulation (heat retention). It achieves breathability, low cost, and lightweight.

The DuPont(TM) Tyvek(R) Software ESB (Emergency Safety Blanket) is an emergency sleeping bag made from high thermal insulation materials. *What is Tyvek(R)?* Tyvek(R) is a non-woven fabric developed by the American company DuPont. It is lightweight, durable, breathable, and used worldwide in applications such as moisture-permeable waterproof sheets for buildings. Source: https://www.tyvek.co.jp/ **Features** - **Thermal Insulation** It uses Tyvek(R) Silver, which has an aluminum coating applied to the soft-type DuPont(TM) Tyvek(R). In addition to its soft texture, the aluminum coating helps retain body heat, ensuring warmth. - **Breathability** Moderate breathability. - **Lightweight** It is light and does not create a feeling of pressure while sleeping. - **Space-saving** It folds down small, saving storage space. - **Low Cost** By adopting a single-layer high-performance non-woven fabric and reducing the materials used, it achieves low cost. Traditional blankets require washing and repacking after use, but this product is disposable, eliminating those costs.

basic information

【Insulation】 ● It has insulation properties equivalent to or greater than that of a blanket. ● When combined with a blanket, it has insulation properties equivalent to those of cold-weather sleeping bags. 【Breathability】 ● It has approximately 160 times the breathability compared to disaster-use aluminum vapor-deposited film. ● Even in cold environments, condensation inside the sleeping bag is less likely to occur. This helps reduce moisture from sweating on the skin, preventing the onset of hypothermia. 【Weight and Dimensions】 ● Approximately 300g each (25cm long × 12cm wide × 7cm high) / 20 pieces per box, approximately 6kg (34cm long × 48cm wide × 22cm high) 【Washing and Repackaging】 ● Not necessary. (For personal use, please dispose of it after a certain period of use.) 【Disposal】 ● Please dispose of it in accordance with the regulations of your country and local government. *DuPont(TM) and Tyvek(R) are trademarks or registered trademarks of a subsidiary of DuPont in the United States.
