Trusted sources have informed me that the best men's underwear ever is made by Mosmann Australia. Mosmann rarely offers discounts, so it was perfect timing to receive a promotional email this week offering 25% off until March 31.

These skivvies are expensive, but they last forever. If you're particular about your down-unders, they're worth every penny. Highest quality, comfy, supportive, and sexy too, they are sure to exceed all expectations whether you are working, exercising, or relaxing. I especially like their selection of prints. In the cheapest scenario (buying a 7-pack with the promo code), they cost around $18 each.

My sources tell me their favorite styles are "Mens Trunk Micromodal" and "Mens Trunk Modal."

The promo code is SWEET25, valid until March 31, 2016. They offer free shipping worldwide for orders over AUD49 (about $37). Important: Never put them in the dryer.
