This is a liquid aerogel that absorbs sweat and keeps you dry during training and competition. It’s not like regular antiperspirant. It’s non greasy, porous and breathable. The aerogel creates a thin barrier that soaks up moisture without feeling sticky. Its great for climbing, lifting, martial arts, and anything grip-based where sweat can mess with your performance. It doesn’t have aluminum or harsh chemicals, stays put through sweat and movement, and washes off easily with soap and water. Aerogel is food grade and non toxic. One bottle gives you about 60 applications.
