Soft and comfortable
Size: Small, Color: 5 Pack - Modal Blue/Red/Grey
My son love that these are longer on his tights than other brands that ride up. No more picking wedgies during sports! Very happy with them as a mama. My son says they are soft and comfortable and asked for me to order more!

Soft and super comfortable
Size: 4-5T, Color: 10 Pack - Covered Waist, Size: 4-5T, Color: 10 Pack - Covered Waist
As my youngest son is growing rapidly, I decided it was time to surprise him with a new set of toddler boys boxer briefs. I loved that this pack came with a set of 10, and it had 7 pairs Monday through Sunday and 3 solid colored ones. It's been so much fun to teach him the spelling of the days and to help recognize the letters. As well as letting him pick his favorite design or color. He is 4 1/2 years old and right in the middle of 4t and 5t clothes. This was true to it's size and fit him perfectly. I love that these are tagless, and the tag print is designed inside. These are super soft, stretchy, and comfortable. Perfect for a preschooler! He is comfortable in these, to play various of sports, wrestling with his big brothers and running around the playground. I love the soft waistband that doesn't put pressure on his waste and wicks moisture, as well as 100% cotton!! Don't forget to tumble dry low in the dryer, or in my case, I just let them air dry. They don't shrink after several washes and seem to last a while! I couldn't be happier with my purchase. Great job to Fruit of the Loom for designing these for my toddler!

Excellent quality
Size: Large, Color: 10 Pack - Breathable Micro Mesh
These boxer briefs are excellent quality and very comfortable for my son. The fabric is soft and breathable, and they don’t irritate his skin. They’ve held up well after many washes without stretching out or fading. The waistband stays in place, and the fit is true to size. Great value for the price — I’ll definitely be repurchasing
