Ground sheet made with Tyvek Silver. Comes with a storage bag. Photos are for illustrative purposes. Size: 185cm x 220cm Two sheets are sewn together with a sewing machine to create a width of 185cm. The seams are not waterproofed. The size is the same as the under sheet for the Arai Tent & Ripen Airiz, E-Rise, and Kayariz 3-person tents. Usage examples: ground sheet, luggage cover, backpack cover, sunshade, etc. Eyelets are attached at the four corners. Leather is attached to the eyelets for reinforcement. Thin cords (strings) of 1m are included, so please cut them to your desired size. The color of the eyelets, thin cords (strings), and leather may differ from the sample photos. The Tyvek logo, etc., will be printed on one side. The design and color may change. Although unused, wrinkles and creases are present due to the nature of Tyvek. The material is waterproof, but please note that it is not completely waterproof. This is made by an amateur, not a manufacturer, so please refrain from purchasing if you are looking for perfection. ★ When shipping, it will be folded to fit the A4 size, 3cm thickness of the Rakuraku Mercari delivery service (Nekopos). ★ Tyvek® Silver is a sheet made by vapor-depositing aluminum onto high-density polyethylene non-woven fabric Tyvek®, and further applying an anti-oxidation resin coating to each fiber to prevent aluminum degradation. Unlike other companies' products that simply sandwich a breathable aluminum layer between thin waterproof films, this is a strong building material that does not easily degrade in waterproofness even after long-term use. From the HP of Asahi-DuPont Flashspun Products Co., Ltd. Thank you for your consideration. #Mountaineering #UnderSheet #Ripen Functionality: Lightweight
