YOULEHEMen's Boxer Shorts Soft Bamboo Underwear Trunks Breathable Multipack

Can you wear these as shorts or would you get kicked out of Sainsbury's?

Are these the trunks that have the chemical when you pass wind it hides the smell

Hi, I’m looking for boxers that are 100% seemless, as in is the material of the main trunk the same as the top? Or is the top tighter?

Do the black long leg boxers have a reinforced pouch (the extra line of stitching at the bottom of the fly to give it a 3D effect)?
