I've purchased these trunks since 2011 and I've ordered 5 packs since.

For the first few months, these trunks hold up great. They are soft, they can stretch, and they don't restrict any movement. And when they stretch, they don't loosen up too much, it stays the right amount of tight. This is great for me because I don't like loose trunks, I like it to hug my body, which is what this does without feeling like it's too tight. No matter how many times I've washed or worn these, they don't lose the ability to hug my body in the right amount of tightness. In a word: snug.

The downsides:
-They don't last long (at least to me): After washing them after every wear, the longest I've had a pair was 6 - 8 months. When I took a pair off, I gripped the waistband and pulled them down. They tore. The fabric under the waistband tore. Now, I admit I may have done it rather suddenly, in a fast motion, but I don't think you want underwear where you have to consciously consider how roughly you are going to pull them down.

-They lose color: Yes, I know black clothing eventually lose color but these started turning that light black color after the second month.

-They are expensive: I used to be a guy who bought those 3 packs of underwear for 10 dollars. At the moment, I haven't been trying to find a cheaper alternative to these because I'm afraid I'll waste money buying underwear that won't live up to these when I need to spend that money on these.

TL;DR: If you have the money and like snug underwear, buy these. If you are a regular joe who doesn't care what sort of underwear he wears, look elsewhere.
