This is a pouch made from 1.0 oz DCF. It has a gusseted bottom, so it's 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, 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 sold 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 (khaki) Body weight: Approximately 7g It uses the same fabric and parts as major outdoor brands, so I think the durability and quality are comparable, but it is a handmade item made by an amateur. I try to sew carefully, but please refrain from purchasing if you are looking for professional techniques or the quality of ready-made products.
