I want to buy white T-shirts to wear under white dress shirts. I picked out two but the differences between the two were not obvious so I bought one of each: Men's polyester sport t-shirt. (White) (X-Large) Augusta 790A Adult Wicking Softball Tee - White, Extra Large This is my comparison in hopes it will help others in selecting a wicking polyester undershirt. First, I should say they are entirely different, primarily in fabric. They are cut almost identically, in a standard T-shirt loose barrel style. The difference in cut is that the Augusta brand has slightly smaller arm holes and arms. The width is almost exactly the same, while the Jerzees is about ½” longer. Both have a printed label. The main difference is in the fabric. The Augusta fabric has the traditional look of a hard, somewhat shiny polyester fabric that you’re probably familiar with. The Jerzees fabric looks and feels remarkably like traditional cotton T-shirt fabric – in fact, if I didn’t know otherwise I’d assume it to be exactly that (I wouldn't know how to tell the difference, other than with a flame test). Maybe more telling is the weight. Each of these are XL size. I washed them before weighing to make sure there were none of the fabric coatings which are sometimes applied to aid in machine handling or to yield a better hand feel or appearance in sales. So these have been washed and dried once: 4.7 oz Augusta 7.6 oz Jerzees To tell the truth, I cannot decide which one I like better. I probably won’t know that until I wear them a number of times and then it will mostly come down to comfort. I did ask a friend which she liked better, and she chose the Augusta. I asked what criteria she used in that decision, and she said it looked nicer. Maybe she didn’t like the looks of a shirt that looks just like a T-shirt. My guesses are that the Jerzees, with its more complex and thicker weave, would probably provide a little more insulation for the winter. Conversely, the thinner and flatter weave of the Augusta fabric might be cooler in the summer. It might take me a while to determine if there's actually a noticeable difference. I’m giving both 5 stars because they are as described and look to be well made. I see no problems with either shirt. BTW, and slightly off subject – I’m sure everyone has encountered ring-around-the-collar. I have a very expensive white formal shirt which developed a yellow ring-around-the-collar. I don’t like sending shirts to a laundry … I don’t know what they do but laundered shirts shrink, come back with cracked buttons, and don’t last very long – not a good way to treat a very nice expensive shirt. I don’t think the laundries have any special trick to remove the ring anyway. I was tired of my good shirts being ruined with a non-removable ring. Bleach doesn’t help a bit. So I set out to research the cause so maybe I’d have a chance of figuring out how to remove it. I found out that it is simply skin oil, which accounts for the yellow color. As you would expect, bleach isn’t going to make yellow oil colorless. The only solution is to remove the oil, so that means attempting the difficult task of removing oil from fabric. For a common household product, Dawn detergent seems to be the best – that’s what is used to remove nasty oil spills from unfortunate birds (assumedly without damage). I mixed up a small jar of half Dawn and half water, then using an old soft toothbrush, gently scrubbed the solution into the ring. Let it sit for a few minutes before washing normally. Depending on how bad the ring is, you may have to treat/wash/repeat a few times. Using this technique I was able to almost completely remove the ring from several expensive white shirts I was too embarrassed to wear anymore. I was able to put them, and the formal shirt, back into my active wardrobe. Taking a hint from this, I now try to prevent the ring in the first place by making sure to scrub my neck especially well in the shower to remove as much skin oil as possible before donning a white shirt.
