At the heart of these cold-weather Mens Impact Pac Boots from Baffin is a moisture-wicking eight-layer inner boot system. Hydromax II and B-Tek four-channel hollow-fiber layers keep the foam dry and filter moisture out of the boots. Leather-like chamois Thermaplush is soft and smooth. Vaporized membranes have a silver surface that reflects heat back toward your feet to keep them warm. Timberwolf leather and Diamond-Lite insulated nylon uppers have drawcord-adjustable tops and crack-resistant buckles so you can cinch them tight to keep out snow. Cold-reflecting polyurethane rubber midsoles. Premium polar rubber outsoles provide maximum grip on the ice. Comfort range down to -148F/-100C during active use. Imported. Ht: 16. Avg. wt: 5.4 lbs./pair. Mens whole sizes: 8-14 medium width. Colors: Black, Snow Camo. Type: Boots.
