Frequently Asked Questions
How do I pick the right merino weight for travel?
Choose lightweight (around 165 g/m2) for active travel and layering, midweight for everyday warmth and versatility, and heavyweight (around 320 g/m2) when your priority is insulation for cold climates. Lighter weights pack smaller and breathe better during activity.
Will merino pullovers stop odor on long trips?
Merino naturally resists odor by trapping odor-causing molecules and allowing them to dissipate; this means you can often wear merino for multiple days between washes, especially the half-zip active styles designed for moisture wicking.
How should I care for a merino pullover to keep it looking new?
Follow the label: many merino garments are machine-washable on a gentle cycle, but hand washing and flat drying extends life. Avoid high heat in dryers and harsh agitation to reduce shrinkage and pilling.
