The benefits of merino

Merino wool is a sustainable fabric choice for eco-conscious con-sumers shopping for activewear. Made from the wool of merino sheep it is both renewable and bio-degradable, and thanks to its natural properties it has a range of benefits which include

Carbon-neutral, biodegradable and sustainable
Thermoregulating, wicking and comfortable to wear straight to skin
Lightweight and insulating protecting you from windchill
Crease-resistant fabric which holds its colour and shape
Does not require intensive washing as natural good bacteria help to self-clean wool

Wash care

Thanks to its antimicrobial properties which make it resistant to odour-producing bacteria, your merino activewear will not need to be washed as regularly. We recommend only washing when necessary, and spot cleaning any stains. You can refresh your garment between washes by gently steaming it or a quick hand wash in the sink with cool water.

Hand wash* with gentle detergent, wool, or baby shampoo
Lay flat to dry on a towel
Apply a gentle iron with a slow steam
Do not tumble dry 

*Why we use hand wash only merino wool

Machine-washable merino wool is treated with a heat-resistant plastic, which cracks as it is washed and tumble dried. Aggressive washing damages merino, causing the wool to pill more, lose its shape and appear worn quicker than caring for hand wash only fibres.

Overall, choosing hand wash only merino wool means items last longer and they’re more environmentally friendly.
