Constructed from a technically engineered fiber formation and brushed back for added softness, this performance fleece provides superior warmth. The microscopic "pockets" within the fiber create a thermal warming effect against the skin, while its moisture management capabilities keep you dry and warm. Its dense knit construction and unique fiber formation give it a lofty hand, making it perfect for layering. Designed with spandex, it offers enhanced fit, mobility, and moisture management. Features include a top access fly opening, a HeatFX branded waistband, reduced bulk with flatlock seam construction, and tagless labeling.
