"The quality of these shorts is seriously impressive. The material feels durable and well made, but they’re still lightweight and comfortable. They fit true to size and the design looks even better in person. You can tell these aren’t shorts that are going to fall apart after a few washes. Definitely made to last. I’ve been really impressed with the quality from this brand."

"My son LIVED in these all summer long! He loved all his flame shorts from Little trouble! How could you not!?! The fire orange checkered ones were definitely his favorite though! And yes, he's riding his E Dirt Bike in the house! Hahahaha!"

"Our grandson looks so adorable in these shorts!! They fit so well and are super comfy! The colors are awesome! It is Thomas approved!"

"This is our 5th pair of LT shorts or something like that. Kiddo always loves the bright colors, the green drawstring is a great touch, they seem super comfy, parents always ask about them (and some older kids do too!) These green ones in particular are nice because with the gradient to yellow flames, it makes it really easy to pick out your kid when playing in the masses. (Candidly the solid orange shorts are even better for this last bit. Get both if you can!) We put these mesh LT clothes in the dryer and the colors hold well."
