Comfortable, durable, and perfect for active kids!
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!

Comfy and good quality
Good quality and my son says they’re so soft and comfy. He won’t wear any other kind! He is 10 years old and very slim and the Medium fit perfect.

Good Quality
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!

Under Armor Briefs
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!

Kids love them, but waistband rolls
My kids love the feel of these underwear, along with the fun colors. They also say that the legs stay in place more than other brands. However, the waistband rolls down after a while. I will probably look for another brand to purchase next time.

True to size! Good Quality! Recommended!
They fit true to size! I purchased the XL size for my 14 year old, as a reference he’s around 5’6 and weighs roughly 120-130lbs. The material is very soft and stretchy. These are the preformance moisture wicking material, perfect for sports. The waist band is a bit on the thicker side which is no problem. I can definitely tell they are good quality garment based on the feel and construction. I definitely recommend!
