Frequently Asked Questions
Is merino wool comfortable in hot weather?
Yes — superfine merino is breathable and regulates temperature, wicks moisture and resists odor, making it surprisingly comfortable for warm evenings. Choose a lightweight knit and check garment weight (the picks here use about 165 g/m2) for best summer performance.
Should I pick merino or a polyester blend for sweaty evenings?
Pick merino if odor control, natural feel and temperature regulation are priorities. Choose a polyester-spandex blend if you need maximum quick-drying performance, stretch for activity, and easier, low-effort care.
How should I care for these polos to keep them breathable?
Follow the label: synthetic blends tolerate regular machine washing and drying on low, while merino benefits from gentler cycles, cold water, and flat drying to maintain loft and fit. Avoid harsh detergents and high heat to preserve breathability and shape.
