Reviews

A perfect base layer

"This long sleeve merino is perfect for cool, cold or rainy weather under a fleece or shell or light rain jacket so you don’t get sticky. Also good open in warmer weather when sun protection and wicking desired. And wont melt to you if hit with IED. Though I haven’t tried this out yet. A tighter weave than I have experienced in other merino wool base layers. Less prone to contact wear and holing I think. I easily washed in sink and dried quickly."

— Tim L. (5/5)

Can't spray it with permethrin, poor durability

"Several things first I'm 6' 175 lbs fairly in shape dude and had to go all the way down to a small to get one that wasnt baggy on me. Secondly apparently you can't spray these with permethrin, I did and it unravels the fabric on the surface and made it look weird, emailed Kuiu about it and their response was basically "well yeah you shouldn't have done that" so in my opinion this shirt is only useful as a sleeping shirt. Thirdly I've only used it with a pack several times and it's already worn holes in it, I know merino is a more delicate fabric but I expect a blend from a brand like Kuiu that costs $100 to last longer than that."

— Kyle W. (1/5)

Merino comfort

"I love these shirts. I have both the hooded and without hood shirts and I wear them almost everyday as a layer up for chilly mornings, evenings, and rooms. They are light enough to wear in room temp and also add warmth in cooler times. Very comfy."

— Sony G. (5/5)

Nice Shirts

"Very nice shirt. 4 out of 5 stars only because I noticed two small holes in the shirt on the first day."

— chris m. (4/5)

— Dean M. (5/5)

Great Shirt

"Fits perfect, really soft , and the coloring is great for where I hunt"

— Kevin H. (5/5)

Go to base layer

"I own several Ultra Merino 120 SS and LS. I wear year around as an everyday shirt, in the fall as a base layer for upland hunting and in the winter as a base layer for skiing. This is an excellent product."

— John Z. (5/5)

GREAT SHIRT

"Great shirt. Incredibly soft and comfortable. Best underlayer I’ve ever worn. In fact, I think I need to buy another one right now."

— will s. (5/5)

Q&A

When did you change the construction of these shirts? I just bought one expecting it to be the standard model. It is a slightly lower weight, 120 instead of 125, and the construction is completely different. The reinforced venting on the side is completely gone. This is the kind of shirt I could get anywhere at a much lower price. Do you have any plans to bring back the older version of this shirt?
We launched the ULTRA Merino 120 LT in late spring 2022, and have discontinued the ULTRA Merino 125.
