What Our Gearhead(R) Experts Are Saying:"I wore the Merino 260 ZoneKnit Legging on a full day of backcountry laps and never had to adjust a single layer. The zone mapped knit actually vented at the spots where I run hottest, not just everywhere at once."High output days punish base layers fast, and the Icebreaker Merino 260 ZoneKnit Legging is built to keep up rather than fight back. This is the layer we pull on before a full day chasing lift laps or skinning uphill, merino wool doing the regulating so nothing has to get peeled off mid run. ZoneKnit technology maps ventilation to the zones that actually overheat, breathing where it counts instead of blanket insulating the whole leg. A gusseted construction adds real mobility through every stride or turn, and flatlock seams stay flat against skin through hours of repeated movement, no chafing, no distraction from the effort itself.
