"The OG" 12 valve Cummins Short Sleeve Tee

We brought back the original Thin Air Diesel shirt from 2015. A very popular and requested item. Use it for formal events, weddings, graduations, Bar Mitzvha's, showing Powerstroke and Duramax guys why they are sub par, or (our favorite) just a rag to check oil. 

NOTE- These do run smaller in size after a wash. We suggest ordering a size larger than you normally wear. 

100% cotton so you wont catch on fire doing hot wrench or metal glue stick activities (no guarantees)
