Please check the profile. This is an outer pack for a super rare hydration pack with the old Gregory logo, which was only released for a few years. If the size is right, hydration packs from brands like Camelbak and Patagonia can be used. Condition: Relatively good condition for its age. There are no holes or noticeable stains. The coating is not flaking off. There is a slight smell typical of old bags, but it can be somewhat removed by putting in an air freshener or odor remover for a few days. [Size] Please refer to the images. There is no noticeable damage on the surface. I think those who are used to vintage clothing will be able to use it without any problems. Please check the images and consider purchasing. Price negotiations are accepted, but significant price reductions will be blocked at my discretion. Please purchase at a physical store if you are sensitive or have allergies. Please refrain from purchasing if you do not understand vintage or used items. I am also selling other bags (Gregory) etc. Here → #BSBJB arcteryx outdoor products eastpak Nike New Balance The North Face Patagonia Berghaus Marmot Snow Peak Columbia Montbell NANGA Mountain Hardwear Manastash Arc'teryx Mountain Equipment Millet Woolrich Sierra Designs Haglofs Chums Mammut Snow Peak ALDIES Outdoor Research KAVU KAVU Mountain Equipment L.L.Bean Outdoor Gramicci MSR Camp Outdoor 1FCDbesidetop2
