We occasionally get questions from customers about which products will stain from sweating and which ones will not. The answer to that question is not related to specific products but to a number of other things. This is not caused by defective or low quality apparel, it is usually caused by outside factors such as sunlight, perspiration, and humidity; even lotions and body fragrances. We also forgot to mention that if you spill your food on your shirt, oops but we are not talking about that kind of stain. This type of discoloration is more common in the summer months and especially so for people who work outside and in hotter and more humid areas of the country. I have seen it happen to office workers who live in hot and humid climates as well construction workers in dry heat. Some contributing factors are even the water in the area that it is washed in and the body chemistry, which can even be affected by the food you eat. It has the potential to happen to any color, brand or blend, but generally to darker or red based colors such as burgundy, blueberry and lilac. The general way to avoid this is to choose white or another un-dyed color such as ash or natural or use 100% polyester.
One of the best best you can have if you have concern or have experienced this type of staining is to buy a better t-shirt and anymore the go to option is an perfect moisture wicking t-shirt which in most cases will now have an anti-microbial (no more stink) element to it. These type of fabrics are available in many different styles.
