※ This listing is for one item as indicated in the title. 【Background】 "The Main Backpack for Tent Camping Shifts from 40L to 35L" In recent years, as mountaineering gear becomes lighter and more compact, backpacks in the 35-38L class are becoming the mainstream for tent camping, replacing the 40L class. However, conventional storage sacks designed for 40L, such as the Hyperlite Mountain Gear PODS, are too large and difficult to use inside a 35L class backpack. Therefore, we developed a storage sack optimized for the inside of 35-38L backpacks. We have created a series of sizes and types to enable efficient packing. 【Features】 ● Self-supporting stuff sack It can store items that tend to get scattered during tent camping, allowing for quick opening and closing. It opens wide for easy access to the contents. ● ITW-NEXUS cord lock is used We use ITW-NEXUS, which allows for one-action cord lock functionality and opening/closing. It combines ease of use and reliability. ● Durable with thick DCF We use thick 1.43oz DCF to maintain the self-supporting shape. ● Stuff sack compatible with Unit Box 35 The bottom is the same size as the separately sold "Unit Box 35." It can be perfectly stacked with the Unit Box 35 series. ● R processing and sewing + seam tape Rounded corners for pressure distribution. Sewing + seam tape reinforces the strength reduction caused by needle holes in the DCF fabric, increasing durability. As a characteristic of DCF fabric, there is a reduction in strength due to the holes from the sewing needles. Seam tape compensates for this, significantly increasing durability. Dyneema tape is very expensive and requires considerable effort, but we consider it an essential specification for items that are compressed and have force applied to the seams. 【STACK35 Series】 Pursuing stackability for 35-38L backpacks. The bottoms are uniform, and even when stacking S/M/L/XL, they fit neatly, and combinations with half-size or drawstring stuff sacks are also possible. This is a series for UL-oriented hikers. 【Specifications】 Size: Approximately 26 x 15 x 23cm Weight: Approximately 21g Material: DCF 1.43oz 【Notes】 ・Decorative items other than the product title are not included. ・Price negotiations are not possible. ・Shipped in simple and compact packaging.
