- DIXXON Mr Horsepower Flannel - Mens XL - Like new condition. May not have ever been worn. **I have a large collection of DIXXON flannels, party shirts, and Bamboos that have been purchased between 2020 and 2025. The photo of the flannel/ party shirt/ bamboo in question is the stock photo. There are simply too many shirts in my collection to post a photo of every single one. If you would like actual photos, please send me a request. All offers will be considered.
