Saxx wins on pure pouch engineering, but Pair of Thieves takes the value crown, and METOIN? It punches way above its weight for the price. If you’re spending $38 on Saxx and not getting a noticeably better pouch experience than METOIN at $20, you’re overpaying. That’s the short version. The longer version involves me actually wearing all three brands for weeks straight, sitting through meetings, sweating through Houston summers, and going to the gym way too hard. So let’s get into it.
Here’s how these three brands stack up head-to-head:
| Feature | Saxx | Pair of Thieves | METOIN |
|---|---|---|---|
| Pouch Design | BallPark Pouch (3D, hammock-style) | Standard contoured pouch | Ergonomic contoured pouch |
| Price Range | $35-38 | $20-26 | $18-25 |
| Fabric | Modal/cotton blend | 95% modal, 5% spandex | Nylon-spandex blend |
| Sizing | Runs small, inconsistent | True to size, forgiving | True to size |
| Best For | Premium daily wear | Value-first buyers | Our customers, hot climate |
| Durability | Excellent (50+ washes) | Good (40+ washes) | Solid (40+ washes) |
Saxx Underwear Review — The Premium Option
Saxx built its name on that BallPark Pouch, and honestly, the engineering is legit. It’s a three-dimensional pouch with a “hammock” structure that keeps your boys separated from your thighs. No more friction, no more sticking. The mesh panel along the pouch seam? That’s not just marketing — it actually adds airflow.
I wore a pair of Saxx Ultra on a 14-hour flight to Dubai last year. That’s 14 hours of sitting, airplane AC blasting at full force, then stepping off into 95°F desert heat. The mesh panel genuinely helped. Air circulation was noticeably better than my regular pairs.
The modal-cotton blend (they use a mix of modal, viscose, and elastane, around 170gsm) feels soft as hell straight out of the package. After 50+ washes, it still holds up without pilling.
Here’s where Saxx loses points: sizing is a minefield. I’m a medium in almost every brand, but Saxx mediums felt like I was wearing a diaper two sizes too small. I switched to large and the pouch support loosened. A customer in Arizona told us modal changed his life in dry heat — but he went through three pairs before figuring out his actual size. At $38 a pop, that’s an expensive learning curve.
The waistband occasionally rolls after heavy washing. Not a dealbreaker, but annoying at this price point.
if you nail your size? The quality is there.
Pair of Thieves Underwear — The Value Play
Pair of Thieves came in swinging with lower prices and a “we’re making underwear comfortable for everyone” vibe. No fancy pouch engineering — their pouch is basically a standard contoured front panel with a small breathable fly. It’s not a revolution, but it’s solid.
I tested their Airlift line for about six weeks. Wore them to the gym (leg day, which is the real torture test), sat through 8-hour workdays with AC cranked to 65F, and took the subway in NYC during August. The thin modal blend (95% modal, 5% spandex) breathes better than Saxx’s heavier construction. Doesn’t hold sweat as much.
Durability surprised me. After 30+ washes, no visible wear. The fabric didn’t pill, the waistband didn’t loosen.
At $24, this is the pair I’d recommend to someone who wants comfort without thinking too hard about it. The pouch does its job. The fabric feels good. You’re not getting the fancy mesh panel or 3D engineering, but you’re also not paying $38.
One thing: the fly is tiny. Practically decorative. If you actually use the fly, Pair of Thieves might annoy you. If you don’t, it’s a non-issue.
METOIN — The Dark Horse
I’ll admit I was skeptical when METOIN reached out. A newer brand claiming ergonomic focus at $18-25? I expected cheap knockoff territory.
I was wrong. Well, partially wrong.
We tested METOIN’s Performance line across three weeks — commuting in Miami heat (90°F+ with humidity that makes you question your life choices), working from home, hitting the gym, and one disastrous road trip where we sat in traffic for 6 hours. The contoured pouch works. It’s not as engineered as Saxx’s BallPark design, but for daily wear? It’s more than enough.
The nylon-spandex blend doesn’t feel as luxurious as modal, but it wicks moisture better in hot climates. I noticed less sweat buildup compared to the cotton-heavy Saxx pairs during our testing.
Sizing runs true, which matters more than brands want to admit. One of our customers returned 3 pairs before realizing he was measuring wrong. When he finally got the right size, he kept ordering. That’s a sizing issue, not a brand issue, but METOIN’s charts are clear enough that he figured it out.
What you sacrifice for the lower price: the waistband lacks that plush, premium feel. It’s functional, not luxurious. And color/pattern options are limited compared to the bigger brands.
For guys in Southeast Asia dealing with actual heat? METOIN is built for that environment. We designed it that way. The price reflects that we’re not spending $10 million on celebrity endorsements.
Where Each Brand Wins
Saxx takes it if you’re after the most engineered pouch possible and don’t mind paying for it. The BallPark design is still the benchmark. Airflow is legitimately better. The fabric quality is top-tier.
Pair of Thieves wins on value. You get 80% of the comfort at 60% of the price. For guys who want something that works without overthinking it, this is the safe choice.
METOIN wins for guys who need underwear that handles actual heat. The ergonomic design, true sizing, and price point make it the practical choice for our climate. We’re not trying to compete with Saxx’s marketing budget — we’re trying to make underwear that doesn’t suck in 90°F weather.
My Honest Take After 100+ Pairs
Here’s the thing nobody wants to say out loud: the difference between a $24 pair and a $38 pair isn’t always $14 worth of better underwear. Sometimes you’re paying for the brand.
Saxx earns its price with genuine engineering. The BallPark Pouch works. The modal quality is excellent. But if you’re buying Saxx because you saw an ad and think it’s the only option? You’re leaving money on the table.
Pair of Thieves is the smart buy for most guys. It’s comfortable, it lasts, and it doesn’t pretend to be something it’s not.
And METOIN? We’re still building, still learning what our customers need. But we’ve had guys tell us our $20 pair feels better in humid heat than anything they’ve tried from the bigger brands. That’s the feedback that matters to us.
Try a few. Figure out what works for your body, your climate, and your budget. Underwear is personal, and what fits me might not fit you.
