Simple sleeveless base layer design proves that the less is more approach combined with proper fit is a winning combination. The smart design of the S-Phyre base layer features the body panels made of 3D Anatomic material. This lightly perforated fabric is breathable and does a good job at pulling perspiration from the body to the outside of the garment to dry. The side panels have a much lighter and an almost aireated material, that acts as an exhaust for heavy perspiration release and promotes air flow for proper venting. The S-Phyre base layer low-volume and soft for all day comfort. Slight S-Phyre branding to keep the base layer low profile and almost anonymous.
