The Spearfish has a flexible frame with vented temples, a TPR nose piece, and TPR temple ends. Designed to contour with the natural curvature of the head, the Spearfish maximizes all-day wearability and comfort. The BH2253PFT also features a PFT lens. Thanks to its chemical and physical properties, Performance Fog Technology is a permanent coating that prevents the formation of condensation on the lenses by absorbing the humidity drops. \nEach dozen is packaged in a retail-ready box.
