Made from Tactel / Lycra® for best comfort and performance and "cool 'n' dry" comfort. A "double thickness" pocket is formed over each breast to firmly hold the carefully shaped plastic inserts in position. Inserts easily removed or fitted while Cool Guard is being worn. They do not touch the skin. Guard inserts Made from soft but strong Polyethylene. Insert extends around under arm for added protection and to better locate the insert in position. Six sizes available. The complete Cool Guard offers protection against painful knocks. Also excellent for Jogging where breast weight can cause shoulder strain. Cool Guard supports the breasts and holds them firmly in position in their natural shape. Most sports bra's merely pull the breasts tight against the chest. Proudly made in New Zealand.
