With a blend of hiking tech and waterproof power, the Monashee ULLR Helly Tech Boot allows us to hit the trail all winter long. Premium suede and moisture-repelling synthetic team up with Helly Hansen's proprietary Helly Tech Performance membrane to keep feet unbelievably dry, even while hiking through mud and snow. When the path becomes icy, slushy, or uneven, rugged HH Max-Grip soles keep us upright on slippery trails.
