【Product Name】 Gregory Zulu 40 GREGORY ZULU40 M/L Size Thank you for viewing. I used this about 10 times after purchase. I am selling it because I am currently using a different one. There are some scuffs on the bottom of the pack, so please refrain from purchasing if you are concerned. How about it for the upcoming autumn mountain season? Please check the photos for the condition of the product!! I really liked the size, which is convenient for both day trips and overnight stays in mountain huts. Also, the back is mesh, which is breathable and less prone to stuffiness!! 【Product Description】 ◦ Season: Model announced in spring 2019 (new model from spring 2023) ◦ Model Name: Zulu 40 (Comes with a dedicated rain cover) ◦ Color: Empire Blue ◦ Back Size: M～L ◦ Capacity: 40L ◦ Weight: 1330g ◦ Recommended Uses: 1-2 night mountain climbing to day hiking ◦ Especially excellent back ventilation (I am personally very satisfied) Also known as the "Rolls-Royce of backpacks" Please feel free to comment if you have any questions or if you would like additional photos.
