After years of development, we’ve been able to combine the power of activated carbon with the benefits of Merino wool in our new Cold Fusion Catalyst technology. The Underguard Base bottom delivers a one-two punch that is effective at reducing your stink while preventing odor from forming at the fiber level. The merino blend also yields excellent warmth when wet and durability that is unmatched.
