Let customers speak for us
from 57 reviewsWell made and cozy!

5'2" 115 lbs, M fit well, not tight. If I wanted close to body first layer, a S might work.

The feel, the thumb loops, and the extra length in arms and torso!

Beautiful look and feel. I love the 100% wool composition in this heavier, non see through weight... sporty and classy!

I am 6' 5" with very long arms and a normal length torso so my big problem is finding shirts with long enough sleeves. Tall sizes sometimes work but then the torso is too long. Since this has the thumbholes, the sleeves are extra long which is perfect for me. The shirt is also very high quality and merino is the best fabric for temperature regulation and warmth. This style is being discontinued but I was able to purchase two; one heather and one solid black.

Excellent. Great fit, war, no itch. Every day wear in cold weather

My size is a Large (extra)Tall. It's rare to find any sweater or base-layer in this size. No other merino base layer is available in this size. The thumb loops allow me to use this as a base layer for cycling, while wearing my favorite short-sleeved bike jerseys. Thanks, Merino 365!

My husband loves his boxer briefs so much I may have to try them myself. Just the right amount of thickness so they are comfortable but dry fast. Best thing I like is they don’t smell. Thanks Merino 365 for an awesome product .

Great color, fit, feel, weight.

I love the color, length and stitching. One of the best quality merino shirts available.

I got two of these shirts and some baselayer leggings and LOVE them all!

So the Rookie at the fire brigade has the locker right beside the door where the fire engine comes out. So if there's a callout during the day, I have to get changed in full view of the general public. I used to hate it till I got these - now I don't care. If I get run over by a bus and the ambos are heading for me with those clothes cutting scissors I won't have the least concern.
Superb quality, beautifully made, warm and cosy. Love the long length.
Very happy with these, super comfy. Keen to see how long they last

The merino fabric is the star of Merino 365
For us it is not about merino just for hiking, trekking, cycling, hunting, fishing, snowboarding, skiing, etc; it is about the power and versatility of natures most amazing fiber.

Merino is incredibly versatile
Wearing merino everyday is easy, the fabric proves to have just as many benefits in the warmer months as the cooler months. We love that merino naturally repels odor and wicks moisture away, among many other benefits. Which is why we wear it 365 days a year.
