FAQ
About Merino Wool
What makes merino wool different from regular wool?
Merino wool comes from merino sheep and has much finer fibers than traditional wool—about 18-24 microns compared to 30+ microns for regular wool. This makes it incredibly soft, non-itchy, and comfortable against your skin. It's also naturally moisture-wicking, temperature-regulating, and odor-resistant.
Will merino wool make me too hot during workouts?
No! Merino wool is naturally thermoregulating, meaning it keeps you cool when it's warm and warm when it's cool. The fibers wick moisture away from your skin and allow excellent airflow, making it ideal for intense workouts in any season.
Is merino wool itchy like regular wool?
Not at all. Our premium merino wool has ultra-fine fibers that feel soft and smooth against your skin. Many customers say it feels even softer than cotton or synthetic materials.
Why does merino wool resist odors?
Merino wool has natural antimicrobial properties that prevent bacteria from building up—bacteria that cause odor in synthetic fabrics. You can often wear merino pieces multiple times between washes without any smell.
Product Care
How do I wash my merino wool activewear?
Wash in cold water (30°C/86°F or less) on a gentle cycle with wool-specific or mild detergent. Avoid fabric softener and bleach. We recommend washing after every 2-3 wears rather than after each use, thanks to merino's natural odor resistance.
Can I put merino wool in the dryer?
We recommend air drying to preserve the fabric's natural properties and prevent shrinkage. Lay flat to dry away from direct heat or sunlight. If you must use a dryer, use the lowest heat setting for minimal time.
Will my merino wool pieces shrink?
When cared for properly (cold water, air dry), merino wool should not shrink significantly. Hot water and high heat can cause shrinkage, which is why we recommend cold water washing and air drying.
How often should I wash my merino wool activewear?
Thanks to merino's natural odor resistance, you can typically wear pieces several times between washes for normal activities, or after each intense workout. This actually extends the life of the garment compared to washing after every single use.
Fit & Sizing
How does merino wool fit compared to synthetic activewear?
Merino wool has natural stretch and recovery, so it moves with your body without being restrictive. Our pieces are designed with an athletic fit that's not too tight or too loose. Check our size chart for specific measurements.
What if the size doesn't fit perfectly?
We offer free exchanges within 30 days of purchase. Simply contact us and we'll send you a different size—you don't need to send the original back until you receive the replacement.
Does merino wool stretch out over time?
Quality merino wool maintains its shape well. While it has natural give for comfort and movement, it returns to its original shape after washing and drying.
Sustainability & Ethics
Is your merino wool ethically sourced?
Yes. We work only with suppliers who follow strict animal welfare standards, including mulesing-free practices. Our merino sheep are raised in humane conditions with plenty of space to graze naturally.
How is merino wool more sustainable than synthetic activewear?
Merino wool is completely biodegradable and renewable. Unlike synthetic fabrics that shed microplastics into waterways with every wash, merino wool breaks down naturally at the end of its life. Plus, you can wear it multiple times between washes, reducing water usage.
Where is your merino wool sourced from?
Our merino wool comes from farms in New Zealand and Australia that meet our strict standards for animal welfare and environmental stewardship. These regions are known for producing the world's finest merino wool.

Can I wear merino wool for high-intensity workouts?
Absolutely! Merino wool excels at moisture management and temperature regulation, making it perfect for everything from yoga to HIIT workouts to long runs. Many professional athletes prefer merino for its performance benefits.
Is merino wool good for sensitive skin?
Yes, merino wool is naturally hypoallergenic and much gentler on sensitive skin than synthetic materials. The smooth, fine fibers don't irritate skin like coarser fabrics can.
How does merino compare to synthetic materials for athletic performance?
Merino wool offers superior odor resistance, better temperature regulation, and moisture management without the clammy feeling that synthetic fabrics can create. It also doesn't retain odors like synthetic materials do over time.
