This is the best underwear, period. After giving it a try a few years ago, I simply can not go back to the standard underwear. Aside from the more visually pleasant look of the bulge, your private parts will not feel constricted as in standard underwear. Trust me, it's so much more comfortable you will never go back.

Show your aussieBums love and they will love you back for a long time to come.
Gentle machine wash in cold water.
Do not tumble dry (better for your aussieBums and better for the environment).
No need to get all fancy and take them to the drycleaners either (in fact, it’s better if you don’t).
And while we’re impressed that you like ironed clothes, do not iron your aussieBums.
Avoid rough surfaces
Note: placement of logo on waistband may differ.
For the best fit, match your sock size to your shoe size.
