The Spada Crucible Baselayer Crew Leggings are base layer long johns made from lightweight fine-knit polyester with elastane, with a soft, brushed interior to trap heat and aid moisture control. The super-smooth outer surface allows outer garments to glide freely over the base layer, and lightweight stretch mesh panels running down the inseams improve airflow. The jacquard branded soft elasticated waistband gives superior comfort and a custom fit, and the open hem construction gives truly comfortable wear with true-flatlock seams.
