It’s taken me a month of ordering and returning various shirts to find the right one. I thought I could share this with you guys and save you some trouble if in the market for new shirts.
These shirts are 100% polyester. They are heavy weight material but also soft and comfortable. By far the best shirts I have found.
If your poly shirts have that mildew-y smell immediately upon getting wet:
Put in washer like usual and start the load. Once the washer fills up, open the lid (which stops the cycle, at least on mine) add about a cup or 2 of standard white vinegar. It’s about $2-3/gallon at any grocery store.
Let it sit with the vinegar in the water for a half hour or so, then close the lid to resume the wash.
No more mildew smell. And no, your shirts won’t smell like Easter eggs. The vinegar dissipates before they’re out of the dryer.
No idea how to bastardize this method if you have a front loader so don’t ask. Ha.
