Nike NRG ISPA Convertible Pants DD3796-247 Size: XL These are Nike convertible pants. The gray section can be detached with the zippers below the knees. I purchased these a few years ago, but I haven't worn them much, so I'm selling them. I've worn them about 3-4 times, so I think they are in good condition, but please check the images for detailed product condition and actual measurements. Please understand that these are used items. Please refrain from purchasing if you are looking for a perfect item or are very particular about condition. Please take a moment to read my profile before commenting or purchasing, as it contains information about price reductions and important transaction details.
