A great new jacket has released from Manastash for Fall/Winter 2011. The outdoor brand presents the Mammoth 4-Way Jacket, which is about as functional as it gets. It comes with a zip-in reversible vest, which can also be worn separately. Furthermore a pretty crazy patchwork pattern is featured on the upper, along with a removable hood. No matter what weather condition, the jacket should be doing its job. OiPolloi has it in stock now.
