Agricultural polyethylene film, 0.03mm thickness, 135x210, 78g Recommended for those who are UL (Ultra Light) oriented. The size is perfect for a 2-person tent. You can enjoy yourself without worrying about dirt. Higher waterproofness and lighter than Tyvek sheets. Compared to Tyvek, it is overwhelmingly compact and easily fits into any small backpack. Please refer to photos 2-5 for size reference. When packing up, putting it in a Ziploc M makes it easy to carry. (Photos 6 and 7 are for illustrative purposes.) When using with a solo tent, fold it to increase thickness or cut it to your desired size. If cut to 90cm width, it will weigh approximately 50g. It will significantly contribute to gram-saving on challenging mountain climbs, touring, and backpacking trips. As this is cut by an amateur, the edges are as expected. Fine dust may adhere due to static electricity, but it is new. Please understand. I will cut it slightly longer. I also have 0.05mm thickness available. This one is more durable due to its thickness and is easier to use in rocky tent sites. For toughness: 0.05mm For small size and lightness: 0.03mm Please consider based on your intended use.
