Easy Care
Rocking my Unbound Merino V-neck… having an every-day outfit I feel good in reduces cognitive fatigue and allows me to put all my focus on the people I love and the things I want to accomplish.

There was no way I could have possibly traveled as lightly as I did without my Unbound Merino gear. I still can’t believe that these clothes feel so good and really don’t smell after so many days worn consecutively; it’s just awesome.

Unbound Merino performs as promised, and has totally simplified how I pack when I travel the world. The shirts are AWESOME and the underwear feels like having your balls cradled by the hands of angels.

I’ve worn the Unbound Merino t-shirt for most of the 18 days I’ve been travelling through Hong Kong and Thailand. Super impressed that this shirt does as promised, it doesn’t smell at all despite no washing for 18 days!

12 days backpacking with same t-shirt & still fresh! @UnboundMerino really came through with their kit.

These are the greatest. They can stand up to a Texas summer!
Excellent pair of undies. Run a bit small so you may want to size up.
I bought a 3-pack of the Black Merino Boxer Briefs and they are truly awesome. Cool and comfortable.
I utilized this underwear on a recent trip to Peru. The garments were very comfortable and super durable. I would highly recommend them as essential travel wear!
