Sitka Heavyweight Hoodie - Fleece mid-layers often come with a lack of efficient moisture transfer limiting the performance of subsequent layers. Sitka solved this problem with a unique waffled construction that accelerates the movement of sweat through the system, preventing it from building up on the inside. The channeled insulation provides some additional warmth, and Polygiene technology controls odor building making this an incredibly versatile mid-layer, that can also function as an outer layer.
