This is a pouch made from 1.0 oz DCF (Dyneema® Composite Fabric). It has a gusseted bottom, making it convenient for storing small items needed for mountain trips or travel, as shown in the third photo. It's also sized to fit a paperback book. If you have a strap, you can attach it to the loops on both sides and use it as a sacoche. ※ As shown in the photos, due to the nature of DCF fabric, there may be wrinkles that occur during the manufacturing process. ※ Seam sealing is not applied. This item is being offered at this price as a prototype. How about it for hiking or a quick outing? Fabric: 1.0 oz Dyneema® Composite Fabric Zipper: Water-resistant zipper YKK® Aquaguard (Black) Weight: Approximately 7g This item uses the same fabric and parts as major outdoor brands, so I believe the durability and quality are comparable, but it is handmade by an amateur. I strive for careful sewing, but please refrain from purchasing if you are looking for professional techniques or the quality of a mass-produced product. #Dyneema #CubenFiber
