I saw many ads for these before curiosity got the best of me, they just arrived today and are legitimately the most comfortable underwear I've ever owned - by far!
I've tried MyPackage, BN3TH, and eventually became a loyal customer to SAXX for many years.
These are unique in the sense that they keep your dick separate from your balls. If you're circumsized, its an indescribable feeling; your entire cock is enveloped around a plush, smooth, cool and very freeing fabric. It's not just a flap in the front, it features a curved seam that folds inward to keep your entire unit in place. The ball pouch is a perfect hammock for the boys. Supremely comfortable.
The biggest deal breaker with competitors was after actively moving around, your junk would fall out of whatever compartment/designated pouch area. Not a problem with these bad boys. Added bonus is your overall package appearance is bigger due to the separation.
Brilliant technology Separatec. 10/10 replenishing my entire underwear drawer.
