In 2014, the last Father’s Day gift I gave my Dad was a lavender polo shirt made with Dri-Fit technology and some khaki cargo shorts for him to wear on the golf course. He loved that shirt so much that he decided to wear it while working and taking my Mom on “hot” dates. He said he loved wearing the shirt so much because it kept him cool and prevented him from sweating so much.
Now, as I reminisce those special times I spent with him, I wonder did the shirt actually keep him dry or was that because the advertising said it would? Dri-Fit fabric is a type of material that is made of a polyester and microfiber fabric. This fabric helps evaporate sweat away from the fabric surface and from your body. As developers have tons of research to support their theory, I want to put it to my own test.
Using the LilyPad Temperature Sensor found on Sparkfu.com, it will determine if the body of a person wearing Dri-Fit clothing increases or stays the same during use.
The sensor detects temperature changes near its surroundings. Sewing the LilyPad on the Dri-Fit garment of a test subject, the sensor will accumulate the data and transfer to the Arduino circuit board and translate the data to code.
Formatting the code would go to the Adafruit Feather nRF52 Bluefruit app. Developed by the woman-owned Adafruit Engineering plant, The Feather is an all-in-one Bluetooth Low Energy board with a native-Bluetooth chip called the nRF53832. 
The Bluefruit acts as a data pipe that can transmit information to your iOS or Android device. The “Check Arduino Temp,” IFTTT applet connects with my Google Docs spreadsheet where the determination of the material does or does not do what is advertised.
