My kid loves these!
My son has sensitive skin and eczema so tags and fabrics are an important part of our lives. He really likes the softness especially after they’ve been washed a few times. He also really likes the colors and patterns. Definitely worth the cost!

A kiddo fav
These seem to be a bit larger than they were in the fall. I placed these against the others we have and there was a noticeable increase in the newer pairs. However, kids grow, so that’s fine. These are my kiddos fav undies. She says she likes “butt coverage” in fun colors to match her skirts. These stay in place and don’t ride up throughout her very active day as she tries to defy gravity.

Softest material!
I have ordered several sets in different sizes as my son grows. These are so soft and stretchy. The material and fit are great!

Great quality
Soft, simple, pure cotton underwear for our boys. Also very well fitting. The boys appreciate the fun colors and patterns. My husband and I appreciate the cotton and solid construction.

Tried and true
Perfect for my 12yo son! We have tried different brands and my son has preferred Primary unders for the last handful of years. They hold up extremely well: waistband doesn't get stretched and weird, material stays soft.
