09-08-2025My 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!

09-08-2025My 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.

09-08-2025I purchased these for my 13 year old son and they are well made. I like they have a nice band around the waist. His underwear cover his backside if his pants are drooping in the back if he bends over. I just ordered another package after buying 3 packs.
