The smooth, lightweight performance of the Phase SL Baselayer Bottom offers moisture-wicking performance and cool-weather performance for highly aerobic performance. Next To Skin Fit: ⢠Snug fit increases the effectivity of performance fabrics. ⢠Sized for a baselayer fit. Phase SL: Superlight baselayer performance for highly aerobic interval activities in warm temperatures. Phasic interval system: ⢠Technology system is designed for variable performance during the active and rest phases of standard interval training. ⢠Stage 1: Hydrophobic Phi yarns wick moisture away from the skin. ⢠Stage 2: Phi yarns disperse perspiration across the fabric surface, improving natural thermoregulation. ⢠Stage 3: High moisture dispersal along the surface allows the fabric to dry quickly during rest without impeding the fabric' s warmth retention. Phasic SL: ⢠Double-knit fabric features a special blend of yarns for improved performance. ⢠Wicking yarns pull perspiration away from the skin. ⢠Hydrophobic yarns limit total saturation to improve quick-dry performance. ⢠2.9 oz/ydÂ2 / 94 g/mÂ2 fabric weight.
