SCIENTIFICALLY ADVANCEDThe process of creating the world's best performance materials began with our evaluation of different Poly Microfibre, weaving processes, color dying and air permeability combinations. This process and material development was completed after eight months of exhaustive scientific testing, using a combination of North American and Asian laboratories, the knowledge and resources of our industry experts in textile manufacturing, color-fast companies, sewing facilities and our own desire to create the highest quality performance materials in the world.The result of these efforts has given FIRSTAR the right to claim sportswear's "best of breed" in moisture-wicking, quick dry apparel. Our MST sportswear products perform as well or better than any comparable garment made by any major brand name on the market.THE FIRSTAR PERFORMANCE ADVANTAGEFIRSTAR's exclusive MST (Moisture System Transference) provides an unparalleled functional level of performance clothing for today's active lifestyles and competitive athletic advantage.
