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 hiking 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, there may be wrinkles due to the nature of the DCF fabric that occur during the manufacturing process. ※ Seam sealing is not applied. This item is being offered at this price as a prototype. Perfect for hiking or a quick outing. Fabric: 1.0 oz Dyneema® Composite Fabric Zipper: Water-resistant zipper YKK® Aquaguard (Dark Brown) Weight: Approximately 7g This item uses the same fabric and parts as major outdoor brands, so the durability and quality are comparable. However, this is a handmade item made by an amateur. While I strive for careful sewing, please refrain from purchasing if you are looking for professional techniques or the quality of a mass-produced product.
