Reviews

The best one.

"Perfect sensations , perfect value for money. I live in France and I’d rather pay €20 for shipping. We have some great stuff in Europe too, but certainly not at this price point. If you want rugged merino—plus great camo and ventilation—there’s nothing better."

— Florian E. (5/5)

Comfortable, Lightweight, and Quick Drying

"I've really enjoyed this shirt so far. I've worn it quite a few times as a standalone layer in temperatures ranging from 55–75 degrees and have been comfortable throughout. The material dries quickly, breathes well, and doesn't restrict movement at all. I'm excited to see how it performs as a base layer once the colder months roll around."

— Timothy H. (5/5)

He Refuses to Take It Off! 😂

"My husband absolutely loves this! From the moment he got it, he hasn’t wanted to take it off. 😂 He says it’s super comfortable, and it looks great on him too. Definitely a great purchase and something he’ll be wearing all the time. Highly recommend!"

— Mayra V. (5/5)

So hoppy

"Thanks for the great products honestly have to say it’s the best base layer I’ve ever owned I’ve tried pretty much everything over the years – Swazi, several Norwegian brands, plenty of international brands, you name it\. But KUIU has genuinely impressed me\. The comfort, fit and quality are absolutely top\-notch\. All the products I ordered lived up to my expectations and more\. From one happy Norwegian hunter will order more"

— Daniel F. (5/5)

Great Shirt, most versatile of all the Merino weights

"I have many of these 145s, a couple 200s, and one 120LT. The 145s are my favorite and are my base layer for any outdoor activity in particular snowboarding. They are warm when they need to be and breathable when I get too warm. Big fan of the fit. XL 6'4" 250#"

— Tim H. (5/5)

Great layer

"Perfect shirt on cool days and I know it’s going to be an excellent base layer because I have the 145 hooded cousin. 5’8 - 173 pounds, the L fits roomy and comfortable."

— Bret C. (5/5)

Comfortable, regulates temp, Alaska 2026

"These were my go-to base layers for 2026 Alaska trip. Flyfishing north of Fairbanks required more of a mid weight, but this lightweight was just right for all the other days. Outside temps were 40-60."

— Peter U. (5/5)

Very happy with this product

"Very happy with this product the only way I can explain it as soon as you feel the cold and start to shiver, it’s like it turns on and warms you back up"

— James C. (4/5)

Great product, super comfy. Shoulders/length

"Great product, super comfy. Shoulders/length fits perfect but arms are slightly long. Maybe I got dmall arms."

— Geoffrey H. (5/5)

Top Tier!!!

"Fit and feel are second to none! Love the pattern. I have this in 3 different colors, and Love it!"

— David T. (5/5)
