I made a picnic sheet using Tyvek from DuPont. This "Hitoyasumi Ikkyu-san" (Resting Ikkyu-san) is made to a size where you can relax alone, have fun with two people, or squeeze in with three people while taking a break or having lunch during a hike, after taking off your shoes. It's no exaggeration to say that I basically climb mountains for lunch and naps, as I really enjoy my time on the summit (lol). Once I reach the summit, I take out my sheet, quickly take off my shoes, eat my meal, and then stretch out my arms and legs to relax alone. It's the best time. Size when unfolded: 180cm (height) x 100cm (width). When folded: 23cm (height) x 13cm (width) x approx. 1cm (thickness). Weight: approx. 115 grams. (There may be slight individual differences.) I don't have any particular special features (lol). I just cut Tyvek to a size that allows one adult to lie down comfortably. However, the biggest highlight is that I used fabric with the old logo, which is rarely seen these days! Also, I attached a rubber loop to one side, so you can use it as you like, such as preventing it from blowing up by using your removed shoes as weights instead of placing them directly on the sheet, or for hanging it to dry after returning home! *Due to the nature of the material (Tyvek sheet), wrinkles will occur. *Please note that while the material is waterproof, it is not completely waterproof. *The Tyvek logo will be printed on one side. *Please understand that it will be shipped folded small. *The color is generally a surprise when you receive it, but please leave a comment if you have a strong preference. *Each item is made with care, but there may be slight individual differences. Please refrain from purchasing if you are looking for perfection like mass-produced items.
