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.
World record-setting Ironman Triathlete
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.

United StatesGreat product- used it while skiing as a first layer and worked really well to keep me warm
United StatesFits really well and seems durable
United StatesIt's a snug fit. Almost could double for training leggings to work out in. Not quite as warm as I'd expect so don't wear it by itself if you were expecting full on thermals. Works with a pair of shorts for outdoor use too.
United StatesThey are excellent as pajamas. Just the right weight and super comfortable.
United StatesWhat's usual? Fits, feels good, doesn't smell after 2 days, looks good. I have everything from Tee Shirts through Crews, Sweatshirts to Long Underwear... all right on!!
