※ 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, the trend of lighter and more compact mountaineering gear has led to 35-38L backpacks becoming the mainstream choice for tent camping, replacing the 40L class. However, storage sacks designed for 40L packs, like the Hyperlite Mountain Gear PODS, are often too large and inconvenient to use inside a 35L pack. Therefore, we developed storage sacks optimized for the inside of 35-38L backpacks. We've created a series of sizes and types to enable efficient packing. 【Features】 ● Self-Supporting Stuff Sack This sack allows you to store items that tend to get scattered during tent camping, and it can be quickly opened and closed. It has a wide opening for easy access to the contents. ● ITW-NEXUS Cord Lock We use ITW-NEXUS, which allows for one-action cord lock functionality and opening/closing. This combines ease of use with reliability. ● Durable with Thick DCF We use thick 1.43oz DCF to maintain the self-supporting shape. ● Half the Size of Unit Box 35 This is half the size of the separately sold "Unit Box 35." Two half-size units can be perfectly stacked within the Unit Box 35 series. ● Rounded Corners, Sewing + Seam Tape Rounded corners distribute pressure. Sewing + seam tape reinforces the strength reduction caused by needle holes in the DCF fabric, increasing durability. DCF fabric has a characteristic of reduced strength from needle holes. 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 undergo compression and have force applied to the seams. 【STACK35 Series】 Designed for stacking in 35-38L backpacks. The unified bottom allows S/M/L/XL sizes to fit neatly, and it can also be combined with half-size and drawstring stuff sacks. This is a series for UL-oriented hikers. 【Specifications】 Size: Approximately 15 x 13 x 17 cm Weight: Approximately 13g Material: DCF 1.43oz 【Notes】 ・Decorative items other than the product title are not included. ・Price negotiations are not possible. ・Shipped with simple and compact packaging.
