This is a roll-top stuff sack made from 1.0oz gray Dyneema (Cuben Fiber). It is made of a material that is excellent in waterproofness and strength, lightweight, and suitable for outdoor use. It is also quite thin and you can see through it to some extent. It is convenient for organizing items or for attaching to your backpack for easy access. This product is not completely waterproof as the seams have not been waterproofed. You may notice unevenness in the fabric fibers, and small wrinkles may appear during production or use, but it will become softer and more familiar with each use. Size: Approximately 39.5 cm (height) x 21.5 cm (width) Weight: Approximately 19g Wrinkles from import, production, or shipping will be present. We strive to make our products with care, but please understand that they are handmade before purchasing. *Items other than the stuff sack in the photo are not included in the product. *If you purchase multiple items, you may receive a discount on shipping.
