Comfortable, durable, and perfect for active kids!

tara speeceOctober 26, 2025

These Under Armour boxer briefs are exactly what we needed for our active son. The fabric is lightweight, smooth, and stretches comfortably, providing excellent freedom of movement. They wick moisture well, keeping him dry during sports and play, and they’ve held up beautifully after multiple washes, no fading, shrinking, or loss of shape. The fit is true to size, and the waistband stays in place without digging in. Overall, these boxer briefs combine comfort, durability, and performance, making them a great value. Highly recommend for boys who are always on the move! Read more

Good Quality

Bargain RigOctober 12, 2025

These Under Armour boys’ underwear are great material quality and super soft. The size chart recommended a smaller size, but I’m glad I went with the XL for my 9-year-old — it fits and looks perfectly. The price was within my budget, especially with the sale, and overall they’re a great buy! Read more

Fit my 10yr old well

Matt HickersonJuly 28, 2025

My son is making the jump from kid-style undies, to boxer briefs. He's on the small side and skinny for his age (60 lbs soaking wet), and we bought size Small. They were just snug enough to fit properly, and not too tight. He say's they feel "funny" but are comfortable. He prefers wearing these when playing soccer. Also, he likes the dark colors and camo.

My kid loves “this version” of his UA boxer briefs. These are fairly slick to the touch and cool. Moisture wicking. True to size. Read more

Under Armor Briefs

Amy PredelusApril 26, 2025

My son loves Under Armour products, and their Boxer Briefs for boys are no exception! These boxer briefs are incredibly comfortable and breathable, which is so important for an active kid. The material is high-quality, soft, and holds up really well even after multiple washes. He says they fit perfectly and feel great all day long — no bunching, no discomfort. It’s clear that Under Armour really puts a lot of thought into making products that are both durable and comfortable for kids. I would highly recommend Under Armour Boxer Briefs to anyone looking for great everyday essentials for their kids. They’re definitely worth it! Read more
