The Tropic uses a multilayered Tricore material that includes a flexible and fast-drying skin-out chest panel. Well shaped to provide both comfort and range of motion. Seams are glued and blind-stitched on exterior layers, and having no interior stitching adding to the comfort. A 360-degree smooth-skin neck with adjustable Velcro closure seal is paired with excellent O-ring seals at the wrists and ankles. The zipper is reinforced at its base. Segmented Trilastic kneepads.
