Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Rated 5 out of 5 by from Great Yoga top Merino has always been my fav material for Yoga practice. This fit is very flattering, in particular the scoop neckline
Date published: 2023-05-13
Rated 5 out of 5 by from Amaaazinnng I am very impressed! I have the green shirt and I wore it for nearly 3 weeks straight with no washing -my non wool wearing family and friends called me crazy- but this shirt handled it beautifully! The last day I went for a big walk and just got too sweaty. Even hanging it outside overnight didn't help and I knew. It was time. So, off to the wash it goes! ☺️ Super excited to buy it in black! If there were more colours I'd be buying those too! I'm 5'3, 140lbs, and curvy and the medium fit really well and held it's shape for the whole experiment. I do tuck my shirts in generally though so that could have helped it's case!

Rated 5 out of 5 by from Great t-shirt I really like this shirt. I ordered the extra large because I didn't want to use it as a base layer, but as an everyday t-shirt. I am 5'6 145 lbs and 38b chest. The fit is perfect. Not clingy, and not baggy. Just right. And the v neck is just as it looks in the picture, not too high and not too low. I find that wool shirts tend to run small. It's a nice lightweight fabric and should be great for Texas summers.

Rated 5 out of 5 by from True to size [This review was collected as part of a promotion.] Perfect cut for a slim person. Thin, which is good as an undershirt. Might be a bit too thin to wear as a top.

Rated 5 out of 5 by from Great feel and fit [This review was collected as part of a promotion.] Exactly what I was looking for in a shirt. It can be worn daily or out hiking and camping with the awesome benefits of merino. Woohoo! The neckline is lovely too!
Date published: 2023-02-23
Rated 3 out of 5 by from Fit didn’t work for me [This review was collected as part of a promotion.] I ordered a size up since I didn’t want a slim fit. However, the top edge of my bra cups would appear just about the v-neck on this shirt. I tried several other bras and had the same issue, so I decided to return the shirt. I’m sure it’s a great cut/style for others, it just doesn’t work for me.
Date published: 2023-02-23
Rated 5 out of 5 by from Just Perfect Exactly what I was looking for. Slim fit perfect as a base layer when I don't want to wear a long sleeved one.
Date published: 2023-01-27
Rated 5 out of 5 by from Nice (This review was collected as part of a promotion.) Soft and warm. Nice colour too. I like it. I wish they offer more bright color though
