FAQ
Women's zip-up merino thermal base layer sets: FAQ
Women's zip-up merino thermal base layer sets from Merino.tech are made from superfine 17.5-micron Australian merino wool. A zip-up merino top lets you open the zip to dump heat on a climb or in a warm room, then close it again when the wind picks up.
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 zip-up merino best for?
A zip-up merino top lets you open the zip to dump heat on a climb or in a warm room, then close it again when the wind picks up. Compare every weight in our merino weight guide.
How should merino thermal base layer sets fit?
Both pieces should sit close to the skin without restricting movement, because a base layer only wicks sweat when it touches you. The top and bottoms come in the same size; if yours differ, use the set builder. 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.
