Review on HeyKing Little Boys Briefs: 100% Cotton Toddler Underwear, Trucks and Dinosaurs Prints, Breathable Comfort - Pack of 6 by Marvin Nadeau

They are machine washable, true to size at the waist, and the seams are well finished. The only drawback is that the leg openings are very large. My son is very slim, so loose underwear is required that opens up his intimate area. I wish the leg openings were smaller! I find that it has to constantly adjust as the fabric folds. Now even with huge leg holes. They are still much better quality than the underwear we bought from our local stores. If your son has thicker legs or a muscular build, they may be a perfect fit. But when he's a beanstalk, leg holes can be a problem.
