Comfortable, soft underware
I purchased the Calvin Klein Kids Boys’ Modern Cotton Boxers for my son, and we are very happy with them. The fabric is soft, breathable, and comfortable for all-day wear, which is especially important for active kids. The fit is true to size and provides a good balance of support and flexibility without feeling tight or restrictive. My son says they feel comfortable whether he’s at school, playing sports, or just relaxing at home. After multiple washes, they have held up really well—no shrinking, stretching, or fading so far. The waistband stays in place and maintains its shape, which adds to the overall quality feel. Overall, these are high-quality everyday boxers that combine comfort, durability, and a trusted brand name. I would definitely purchase them again.

Soft, Breathable & Mom-Approved
I love these mostly-cotton underwear for my boys. We’ve really been trying to steer away from polyester and heavily mixed fibers, especially in sensitive areas, so I was happy to find these. The material feels soft, breathable, and much more comfortable against their skin. As a mom, I pay attention to what stays in contact with our bodies all day, and I truly believe fabrics matter. Our skin is our largest organ, so I try to choose more natural materials whenever possible. These wash well, hold up great, and my boys actually like wearing them with no complaints about itching or discomfort. Definitely a repurchase for our family. They’re not made cheap, the material is thick and smooth.

His favorite underwear — we’ve bought these for 2 years!
After trying several different brands, these are hands down my son’s favorite underwear. We’ve been buying them for about two years now because he says they’re comfortable and breathable. He actually prefers sleeping in them too, so most nights we’ve basically eliminated the need for pajama bottoms! 😂 They’ve become one of those things I just keep repurchasing as he grows. Definitely a favorite in our house.

Our Go‑To Boxers – Comfortable, Great Fit, and Worth Reordering
I’ve bought this 8‑pack three times now simply because we like them so much. The fabric is soft with the perfect amount of stretch—comfortable for everyday wear but still holds its shape. They wash nicely, never sag or twist, and my son loves how they feel. As he grows, I’ll just keep sizing up—these are definitely our go‑to underwear.

Too good
Got these for my son as they were priced equivalent to lesser brands. They fit well and he loves the brag factor.

Bonitos pero pide una medida más si no eres muy delgado.
Buena calidad. La tall mediana corresponde a 10 años max y si es muy delgado le quedaron súper bien. Si está más corpulento o llenito debes escoger la talla siguiente. Mi hijo de 12 le quedaron por ser el muy muy delgado. Es deportista. En la foto lo comparo con uno viejito.
