Icebreaker sources high-quality merino wool from New Zealand’s Southern Alps, spinning active layers well-suited for adventures in those very same rugged mountains. Not only do Icebreaker’s BodyfitZONE base layers and MerinoLOFT insulated midlayers have a sustainable storyline behind them, but they’re also some of the best we’ve ever tested.
The wooliest of alpine creatures, merino sheep are evidence that, try as we might, humans can’t always beat Mother Nature at her own game. First of all, merino wool adapts to changing temperatures and fights odor much better than its synthetic imitators—which also happen to be significantly more flammable. Plus, the fleecy merino is lighter, more comfortable and dries more quickly than your run-of-the-mill wool.
This isn’t speculation; it’s science. And while the Active Junky team hasn’t spent much time in a lab, we’ve put in enough cold days of testing Icebreaker layers to attest to these claims. [Editor’s note: Except with regards to flammability—we’ve yet to set our base layers on fire, though we’ll keep you posted if anything changes.]
