## Description

A slimmer, more athletic cut with superior performance fabric. 4-Way stretch fabrication allows greater mobility in any direction. Moisture transport system wicks sweat & dries quickly. 3 per pack.

Review: Great value! - Sizing is spot on (usually a 8/10 or Medium in boys - he’s 9), and they fit very well. The review from my kids are that they are very comfortable. This is the third pack I bought and I like the color options.
Review: Son loves them - These are really good quality. I purchased these and some by quicksilver and these cost more but they’re made so much better. So spend the extra money so your child doesn’t have holes in his underroos right away. Also the fit was true to size.

### ⭐⭐⭐⭐⭐ Great value!
*by M***Y on June 17, 2026*

Sizing is spot on (usually a 8/10 or Medium in boys - he’s 9), and they fit very well. The review from my kids are that they are very comfortable. This is the third pack I bought and I like the color options.

### ⭐⭐⭐⭐⭐ Son loves them
*by J***A on June 9, 2026*

These are really good quality. I purchased these and some by quicksilver and these cost more but they’re made so much better. So spend the extra money so your child doesn’t have holes in his underroos right away. Also the fit was true to size.

### ⭐⭐⭐⭐⭐ Comfortable, durable, and perfect for active kids!
*by T***E on October 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!
