New! Air-Conditioned Vest (Fan Vest) Ninja Pocketable, LL Size This is a new, unused item. The outer box has some tears. I personally use the L size of the same product. I use it in "turbo" mode during my 1-hour motorcycle commute. Although it's hot, the wind hitting my body helps reduce the stickiness from sweat. Also, because the fan's air flows upwards, it helped reduce the stickiness around my neck during the rainy season. I find it very useful. The battery is small, so it's easy to carry around. Photos are included. However, a drawback is that because the battery is small, the maximum usage time is only 5 hours. Please understand this before purchasing.
