Reviews

10/10

"Incredible. We are trying to conceive and my wife has switched out most of our items for no tox things. These are the most comfortable boxers ever. I am a wildlife officer, often in hot and even wet environments, and these dry really quick."

Ciara F. (5/5)

Works great

"Living on the coast and working inside and out, swamp ass is almost guaranteed any time of the year. These help out a bunch with wicking and smell."

Cesar M. (5/5)

Fantastic for hiking!

"These underwear are great for athletes. I have already put both pairs through extremely intense workouts where I continued to wear them (on purpose) through the rest of the day to test them. They dried quickly and did not give up any support. I was extremely impressed."

Jesse C. (5/5)

Better than smartwool

"I’ve owned smartwool briefs which are good. SW briefs are a higher % of wool, but they sag much much more than the kuiu. I’ve had the kuiu for two months now and they have yet to sag. Very minor pilling, but doesn’t seem like it’ll be an issue long term. I’ve pushed them to three days in a row without a wash and they didn’t stink, but I did. I’d 100% repurchase, especially at sale price."

Christian J. (5/5)

Wear them every day!

"The material is ideal for any condition or temperature. Keeps you comfortable at all times!"

Alan J. (5/5)

Cannot recommend

"Comfortable for about 6 hours. Legs stretch out and ride up. I don’t blame Kuiu, it’s typical merino. Thought these might be better but I was wrong. Don’t waste your money."

Anthony E. (3/5)

Shoot

"Starting to pill 💊 up on the first day of use. Thought for the price they would be amazing brand dosen't mean anything"

Lupe D. (1/5)

Super Nice!

"The underwear is very comfortable, I was in Spain and needed some better quality clothes, I couldn’t wash my clothes every day, the quality is off the charts, temperatures are around 75 to 90. Never overheating, super soft! can’t wait to use them for the upcoming archery season! No more cotton underwear!! Thanks KUiU!!"
