The compression tee is a stretch shirt with a greater tensile strength than spandex. The tightness increases the blood flow which carries oxygen to the tissues. The process of wearing compression wear while exercising makes the movements more efficient and the whole routine less tiring.
The tight fit of the clothing increases one’s awareness of body position and self-movement, plus it helps you to improve your movements and your posture. Wearing compression tees reduces the accumulation of lactate in the muscles and stimulates the flow of oxygenated blood to those muscles.
The compression fabric may be composed of microfiber, or it may be a combination of spandex and nylon. In each case the fibers will stretch in four directions to completely hug the body. The compression shirt is made of fabric that breathes, protects against rashes, and may even provide added UV protection.
