I heard of certain brands of boxer briefs already having a 'pouch/pocket' that is practical to store a packer but I can't remember it....It wasn't from a trans related store either. Sorry for the lack of details but does anyone know which ones I am referring to?

I think there are several brands now that have boxer briefs with packing pouches... There's Andrew Chistian, RodeoH, Private Structure etc.

Maybee not the brand you're thinking of but Diesel have a lot of boxer briefs and trunks with built in pouches. I have several pairs and they work great for packing.

The Dutch company Danae does boxers with pouches, found them today
