Love BRANWYN or pay nothing

Not sure about wool?

Merino is super soft like cashmere!

It works equally well to keep you cool & dry in the summer as it does to keep you warm & dry in the winter.

We know you'll love it! But just in case you don't, we’ll give you a full refund.

The First Try Guarantee applies to US orders only and does not apply to "Bundle & Save."

1 Year Warranty Replacement

Our seamless Merino bras and underwear are designed to hustle as hard as you—lasting 2–3 times longer than cotton or polyester.

And if it doesn't hold up in the first year of normal* use from the date of receipt? We’ve got your back (and your top drawer) with a free replacement.
