FAQ

Frequently Asked Questions

Is merino wool itchy?

No. We use superfine merino fibers (17.5–19.5 microns) that feel soft against the skin — nothing like traditional wool.

How do I wash merino wool?

Machine wash cold on gentle cycle with mild detergent. Lay flat to dry. Avoid fabric softener and bleach.

How long does shipping take?

Orders ship within 1–2 business days. Standard delivery takes 3–7 business days within the US. Shipping is free on orders over $49.99.

Do you ship internationally?

We currently ship within the United States only. International shipping is on the way — subscribe to our newsletter to be the first to know.

What is your return policy?

How do your sizes fit?

Is there a warranty?

Yes — every MERINNOVATION item is covered by a 1-year warranty against defects in materials and workmanship, no matter where you bought it. Register your warranty to speed up future claims and get a one-time 20% discount code.

I bought on Amazon — does the warranty apply?

Absolutely. Keep your Amazon Order ID (format 123-1234567-1234567 — you'll find it under Returns & Orders in your Amazon account). Returns of Amazon purchases are handled through Amazon according to its policies, while warranty claims come straight to us.
