The Pure 18 shirt is ideal for warmer days as a stand alone layer or as a base layer with the Pure 18 Lightweight Jacket. This poly blend 4 way stretch shirt is heavier than your standard base layer garment providing an optimal weight and performance balance. The DWR treated fabric creates a breathable water resistant membrane to keep out moisture. The integrated vented facemask can be worn in the front for quick access or tucked away when not needed. Sized with a loose fit for added air flow and an extended hem and arm length for extra sun protection, the Pure 18 Tactical Hoodie is ideally worn on its own, next to skin in warm conditions.
