I've started decluttering my mountaineering, outdoor, trail running, and running gear. OMM Original Mountain Marathon PHANTOM 25 Phantom 25 Large-capacity vest-style backpack Retail price: 35,200 yen The Phantom series was developed for fastpacking-style mountaineering, as seen in mountain races. The main feature is a unique harness system that reduces pack sway with seven support points. The Y-shaped harness behind the neck fixes the pack's center of gravity to the center of the body = the spine, and does not hinder the movement of the shoulders, allowing for a more natural running form. Even on rough roads, the V-shaped anchors on both sides tightly adhere the pack to the back, suppressing both horizontal and vertical sway. Features: Adjustable back length with titanium pegs ⭐︎Carbon fiber core material EVA resin shoulder belt harness Large back mesh pocket Front bottle pockets x 2 Zippered belt pockets x 2 ⭐︎Duomat sleep mat Reflective logo Hydration compatible Front mesh pocket Notes: Items marked with ⭐︎ are not included in the sale. Weight: 505g Capacity: 25 L Back length: 46-54 cm Fabric: Cordura, 30-denier nylon Color: Black Purchased new about 2 years ago, and used a few times by a family member (male, 164cm, 56kg). When the carbon fiber core material was inserted into the pack during the first use, it damaged the pack's fabric, which has been repaired (photos 18-20). The pack fit the body better without the carbon fiber core material, so it was not used after the second time. Defect: The ⭐︎carbon fiber core material and ⭐︎Duomat sleep mat that were included at the time of purchase are not included in this sale. Other than the fabric repair, I think it is in very good condition. However, as it is a used item with a defect, please refrain from purchasing if you are looking for perfection.
