Men's 320gsm heavyweight merino base layer tops: FAQ

Men's 320gsm heavyweight merino base layer tops from Merino.tech are made from superfine 17.5-micron Australian merino wool. Heavyweight 320gsm merino is our warmest weight, built for deep cold and low activity such as winter camping, fishing, stalking and long days on the chairlift.

Merino regulates your temperature, wicks sweat and resists odour, so you stay comfortable for longer and wash less. Orders over £49 ship free across the UK, with 30-day returns.

Who is 320gsm heavyweight merino best for?

Heavyweight 320gsm merino is our warmest weight, built for deep cold and low activity such as winter camping, fishing, stalking and long days on the chairlift. Compare every weight in our merino weight guide.

How should merino base layer tops fit?

Close to the skin without feeling tight. Our tops are true to size: size down for a snug layer under a jacket, or size up to wear the top on its own. See the size guide.

How do I wash merino wool?

Turn it inside out and machine wash at 30°C or lower on a wool or delicate cycle with a wool-safe detergent. Skip fabric softener, dry it flat or on a hanger and never tumble dry.
