The MONS ROYALE Ascender Merino Seamless Neckwarmer keeps your neck protected without the bulk or irritation of traditional neck gaiters. This seamless design blends merino wool with Tencel for temperature regulation that works whether you're grinding uphill or ripping downhill, while a thermo-mapped design places warmth and breathability exactly where you need them. When traditional scarves are too bulky and balaclavas are overkill, the Ascender is just right.
