United StatesWashing issues
It’s hard to wash them every time by hand !!
Rounderbum Canada
Dear Jose Thank you for your comments, Washing this product by hand avoids the pads get twisted or damaged inside ;) we kindly recommend you to follow the washing instructions.
United StatesLove them
I wish u I could get a slightly thicker pad!
Rounderbum Canada
Thanks Michael :D Thicker pads are also available online , these work only for padded boxer trunks and padded boxer briefs :)
United StatesNot padded in front.
I understood these padded briefs were padded in, both the front and back. This is not the case. I’d recommend them to someone looking to boost the duke only.

Dear Jeff Thank you for your comments. The products to enhance the front and back are called Padded + Smart Package cup. This Basic Padded Brief is only to add more volume to the butt :)
