This is a handcrafted UL backpack, approximately 15L~23L. Basic Specs: Fabric: Dyneema Xgrid Front pocket, shoulder pockets: Power Net Bottom pocket: Venom™ UL Stretch Mesh Back cushion, shoulder cushion: 3D Spacer Mesh Height: 665mm × Width: 235mm × Depth: 140mm Back length: 410mm Backpack weight: Approximately 370g Back pad: Approximately 22g Approximately 15L to the back, approximately 19L including the roll-top, and approximately 22L~25L overall including the pockets. For everyday hiking, I often used the "Yamato Michi MINI2" for both day trips and overnight camping. I liked its usability and comfort, but as I lightened my load, I started to feel that the backpack's capacity was too large. In particular, the MINI2's fabric is thin, and it cannot maintain its shape if there is space inside the backpack. Every time I carried a flimsy, misshapen backpack, I thought, "I wish I had a smaller backpack." So I started making one. I had previously made a "pa'lante" "Simple Pack" (approximately 35L), so I downsized it based on that. When I actually used the prototype, I found areas with poor usability, and I made improvements each time, gradually getting closer to the backpack I wanted. The back panel has 3D Spacer Mesh, and a pad is inside, but it can be removed. Those who are good at packing and don't need it, or those who want to focus on weight reduction, may not need it. The pad inside will be cut with scissors. Please note that the cut surface is not very clean. #SLOTH_HIKE [Search terms] #Mountaineering #Hiking #Outdoor #Thru-hiking #Long Trail #outdoor #Mountains #Gear #Handmade #Handcraft #MYOG #Self-made #Zack #Backpack #Rucksack #Backpack #UL #Ultralight Material...UL/Ultralight Size...11〜25 L
