Modal Ultra-soft Boxer Briefs (Boys)
Made with
parents in mind.
-
My oldest trained early around 26 months, but every store-bought pair was way too big—it was so hard finding smaller sizes.
-
Why don't we create a size starting from 18 months? That way, even slim kids have great options.
-
I want something thin, cool. Modal-spandex would be perfect. Pure cotton actually made them sweaty and cranky.
-
Awesome! That’ll help beginners and sensitive little ones transition without any fuss.
“ After hopping between endless brands,
my child finally settled on this one.”
-
Switched to Konny after trying other cotton undies,and the stretch and fabric quality are amazing.
Back again to order a size up! -
First kid loved it, now my second is hooked too! Konny undies are soft and squeeze-free,
so my kids refuse to wear anything else. -
Konny is our go-to for daily wear
and stay-home fits,and these undies are no exception!
Couldn't pick a favorite,
so grabbed both briefs and boxers—a total hit.
