I am selling the highly popular mont-bell Fanblow Vest. This is the latest model, purchased in June of this year. It has only been used three times and is in near-new condition. It comes as a set with a dedicated fan (19V compatible) and a dedicated battery (19V compatible). Currently, it is already sold out on the mont-bell official store, and it is difficult to obtain this product this season, so this is a great opportunity for those who have been looking for it. Please note that returns and price negotiations are not accepted. I am committed to a smooth and secure transaction, so I hope that those who understand this will purchase it. 9/24 Addition: Shipping will be on weekends and holidays due to work commitments. * The number of days until shipping has also been changed. 10/4 Addition: Due to the buyer's circumstances, the transaction was canceled, so I am relisting it. Thank you for your understanding. The following is a copy from the official website: This vest is designed to be used with a dedicated fan and battery, making it ideal for activities during hot weather. The structure allows air drawn in from the fan to efficiently pass through the back of the collar and the sides, promoting the evaporation of sweat and allowing you to stay comfortable. The asymmetrical placement of the fans is designed to avoid interference with shoulder straps when wearing a small backpack. A breathable 3D back panel is also included on the back, creating an airflow path. The 3D back panel is removable and can be used separately on a small backpack.
