Let me tell you, these New Balance boxer briefs are a game-changer for active kids! I bought them for my 10-year-old soccer enthusiast, and they've held up through countless practices, games, and laundry cycles.

The moisture-wicking fabric is the real MVP - no more complaints about sweaty discomfort after sports. The stretchy material moves with my kid during all his crazy parkour attempts (yes, we have a little daredevil).

I was skeptical about the polyester blend at first (I'm usually team cotton), but the breathability surprised me. They dry crazy fast after swim lessons - just toss them in the wash and they're ready by next morning.

One thing to note: they run slightly small. My son usually wears Medium (10-12), but we sized up to Large for a perfect fit. The waistband stays put without digging in, which means no constant adjusting during baseball games.

The colors stay vibrant even after multiple washes - no fading like some other brands we've tried. At about $5 per pair in the 4-pack, they're a solid value compared to similar performance underwear.

Only minor complaint? They're a bit shorter than expected - more like a 3" inseam than 3.5". But my son actually prefers this length under his athletic shorts.

Pro tip: Skip the fabric softener - it reduces the moisture-wicking properties. Just cold wash and tumble dry low keeps them in top shape.

After testing these for two months with an extremely active kid, I can confidently say they outperform regular cotton underwear for sports and daily wear. We'll definitely be buying more!
