## Description

Fabric: Spandex/Lycra Applicable gender: neutral/male and female Product features: Use this mask to simulate high-altitude training in plain areas. In a high-altitude environment, the air is thin, the oxygen content is low, and the blood cannot absorb oxygen normally as usual, so the heartbeat will speed up. Training under this ring can strengthen vital capacity, diaphragm, heart load intensity, anaerobic threshold, etc. So when you return to a low altitude environment, your athletic performance or training will improve, so generally some people will go to high altitude for training.
