When EcaPants were still being made, they were one of the hottest EC items out there. I just have a few pairs that were floating around my office and resurfaced after every thing else had long been sold out and removed from my website.
EcaPants are training underwear with a flap to make pottying very easy. Made in USA.
This pair is size XS, in nonwaterproof cotton with pink and white bicycles on a pinkish orange background, and Velcro side closures.
