US specification Tyvek sheet, for use as a ground sheet. ※The first photo shows it folded. Grommets are attached to the four corners, allowing you to secure it with pegs. It looks cool with the logo, even if you use it for MYOG. The following is the description: ・This is a ground sheet made of English version Tyvek. 　The English version is rarely available in Japan, so you won't see it used by other campers or hikers. I happened to get some this time, so I'm offering a limited quantity. ・Tyvek is a lightweight material with excellent water resistance and strength. ・Sheet size: 91.4cm x 210.0cm, Weight: 121g 　There may be slight variations depending on the individual sheet. ・12mm inner diameter grommets are attached to the four corners. 　They are made of aluminum and may be slightly crushed, so the actual inner diameter is about 10-11mm. I've attached them as securely as possible, but due to the nature of the material, it will tear if excessive force is applied. When removing pegs, etc., please be careful not to pull on the Tyvek itself. Ultralight Hikers Depot
