YOUR BODY CHANGED. YOUR UNDERWEAR DIDN'T.
Nobody told you. Not your doctor. Not the brand that sold you "performance cotton." Not the ad that promised "all-day comfort."
But your body knows.
After 35 years old, your testosterone drops 1-2% per year. Your thermoregulation shifts. You run hotter. You sweat in places you didn't at 30. Your skin gets thinner, more sensitive, less tolerant of cheap fabric.
And that cotton boxer you've been wearing since your 30s? It was engineered for a 25-year-old body running cool. Not yours. Not anymore.
HERE'S WHAT'S HAPPENING RIGHT NOW:
By 10am — Cotton has absorbed 27x its weight in moisture. It's holding every drop against your skin. You're sitting in it.
By 2pm — Warm, damp, dark. The exact conditions bacteria need. The itch starts. The odor builds. You adjust. Again.
By 6pm — Friction has been grinding against your skin for 10 hours. The chafing you blamed on your weight, your age, your job? It's the fabric. It's always been the fabric.
THE NUMBERS YOUR UNDERWEAR BRAND WON'T TELL YOU:
41% of men between 41 and 55 experience night sweats. (OKPRN Study)
50% of men have prostate changes by 50. (NIH/StatPearls)
33% of men in their 50s have varicocele. (Tandfonline 2018)
These aren't rare conditions. They're the normal physiology of a male body at 50. And not a single underwear brand designed for any of it.
Until Ares Underwear.

Yes, but handle with care. Use cold water and mild detergent on a delicate cycle. We recommend using a mesh laundry bag (included with your order) and letting them air dry. This simple routine keeps your silk boxers soft and durable for years.
Silk is a natural protein fiber valued for its exceptional softness, breathability, and smooth texture. In boxer shorts, silk provides a luxurious feel while actively regulating temperature and reducing friction—keeping you comfortable all day long.
Because their smooth, natural fibers minimize friction, allow skin to breathe, and reduce irritation. Unlike synthetics that trap heat and disrupt comfort, silk is hypoallergenic and gentle—making it ideal for sensitive skin and daily wear.
Silk is naturally breathable and temperature-regulating, wicking moisture away and allowing airflow to keep you cool and dry all day. Cotton absorbs moisture and stays damp, while synthetics trap heat—silk outperforms both.
While silk feels delicate, our boxers are designed for durability. With proper care (cold wash, air dry), they can outlast many cotton or synthetic boxers. The reinforced construction and premium 6A silk ensure long-lasting quality.
Yes. Premium Mulberry silk-blend lining is hypoallergenic, breathable, and exceptionally soft—making it ideal for everyday comfort. The smooth fibers are gentle on the skin and help prevent irritation and chafing, even during extended wear.
Silk naturally maintains optimal temperature by wicking moisture and allowing heat to dissipate. This breathable design keeps you cooler in warm conditions and comfortable in cooler weather—ideal for all-day wear in any climate.
Our anatomical engineering provides structured support without compression. The contoured pouch maintains natural positioning while the anti-roll waistband stays flat. The result: no ride-up, no adjusting—just all-day comfort.
Yes. Our contoured support pouch is designed to maintain optimal positioning and reduce pressure points. You get the freedom of boxers with the structured support of a brief—comfort and confidence in one design.
Absolutely. The engineered fit and seamless construction prevent bunching and ride-up, even during movement. Whether you're at the office, gym, or traveling, these boxers stay put exactly where they should.
With proper care (cold wash, air dry), our premium silk boxers maintain their shape, softness, and durability for years. Many customers report their first pairs still look and feel new after 12+ months of regular wear.
No problem. We offer free size exchanges—just contact us and we'll send the correct size at no charge. Our 30-Day Guarantee means you can try them risk-free.
"The boxer that finally solves sweat, chafe, and ride-up . Engineered silk keeps you cool and friction-free through 12-hour days."
"Tap into primal comfort the way nature intended precision-engineered silk maintains the cool, breathable environment proven to support peak male vitality."
"From boardroom to gym, stay cool and focused. The engineered comfort that helps you show up at your best, everywhere."
NIGHT 1
Thermoregulation activates
The silk-blend lining releases heat instead of trapping it. Your body stops fighting the fabric. Deep sleep where 70% of daily testosterone is produced finally happens uninterrupted.
40% of men over 40 report night sweats. The fabric you sleep in isn't neutral.
DAY 4
You stop thinking about it
Silk-blend moves moisture 1.5x faster than cotton. By day 4, the adjusting stops. The friction stops. The 3pm itch stops. Your body goes quiet.
That's 5% of your attention back. Every hour. Every day.
MONTH 1
The new baseline
Better thermoregulation → deeper sleep → more testosterone → more energy → sharper focus. One fabric change. Every system benefits.
Harvard documented it: breathable underwear = 25% higher sperm concentration, 14% lower testicular stress. (Human Reproduction, 2018, N=656)
Your hypothalamus regulates your body temperature. When testosterone declines after 40, that system gets less precise. You overheat. You sweat at night. Cotton traps that heat. Silk regulates it.
AresSilk Mulberry silk-blend lining is 30% more breathable than cotton. It doesn't trap — it releases. Built for the 41% of men who wake up damp and the 100% who run hotter than they did at 30.
Cotton absorbs moisture and holds it against your skin. All day. That's not "breathable." That's a sponge.
Silk-blend moves moisture 1.5x faster than cotton. It wicks, it releases, it dries. Including post-urination moisture — discreetly, without the damp feeling. Because 1 in 5 men in their 50s deals with that, and nobody talks about it.
Most underwear compresses the pelvic zone. Tight waistbands put pressure on the prostate area — aggravating symptoms for the 50% of men with BPH by age 50.
ARES uses an anatomical non-compressive waistband. No pelvic pressure. No restriction. 34% less friction than cotton (TRI Labs). Built around your body, not against it.
My husband is an engineer. He optimizes everything his sleep, his supplements, his workout routine. I asked him when he last bought new underwear. He couldn't remember. I ordered Ares Underwear. He wore them for one week and replaced his entire drawer without being asked. First time he's optimized below the belt.
Spent $4,000 on supplements last year. Upgraded my mattress, my pillow, my protein. The biggest daily comfort improvement cost me $9.37 a pair. The irony isn't lost on me. The silk-blend lining keeps me cooler all day. Should've done this before the $400 sleep tracker.

As a men's health specialist, I'm trained to be skeptical of fabric claims. Then I looked at the composition Mulberry silk-blend lining with viscose moisture management. This isn't marketing. It's functional textile science. I wear them daily. I've mentioned them to patients with chronic groin irritation. The feedback has been consistent.

I'm usually a cotton guy. But these silk boxers feel totally different in a good way. Super lightweight and smooth, like you're wearing nothing at all. No sweating, no sticking, just comfort. After a few wears and washes, they still hold up great. Didn't think I'd be converted, but here we are.

I've been buying my husband's underwear for 26 years. He's never once had an opinion. I switched him to Ares last month. Yesterday he asked me to order more. In 26 years that man has never requested underwear. Something is different and I like it.

Honestly, I bought these out of curiosity, and now I don't want to wear anything else. The silk feels incredibly smooth, they breathe well, and they just look great. I wear them during my long office workdays, super comfortable all day. Definitely recommend giving these a try.

Super comfortable. The first pair didn't fit, but customer service helped me exchange them quickly. Light, soft, no irritation, and stays fresh all day. A bit pricey, but worth it.

Got these silk boxers for my husband and he's genuinely impressed. I wasn't sure if silk would be his thing, but now he's asking if there are more colors. Definitely a successful present. I hope they will add more colors in the future.

Wasn't sure what to expect, but these silk boxers surprised me. Super comfortable, light, and they actually stay in place. They feel cool against the skin and give just enough room without feeling too baggy. Great for lounging around the house.

We're Thomas & Samir, best friends and founders of Ares Underwear.
While exploring Singapore's vibrant markets, we stumbled upon silk boxers that promised unparalleled comfort.
Intrigued, we tried them—and the difference was remarkable.
The luxurious softness and all-day breathability were unlike anything we'd experienced.
That discovery inspired Ares Underwear: bringing premium silk comfort to men who refuse to settle for less.
Research Shows Ares Underwear’s Real Impact:
25%
Higher sperm concentration in men wearing breathable fabric vs. tight underwear. Not a supplement. Not a protocol. The fabric.
41%
of men over 40 report night sweats to their doctor. Declining testosterone disrupts your internal thermostat. The fabric you sleep in either helps or makes it worse.
93%
93% of women find their partner more attractive when he wears Ares Underwear boxers.

I ordered these at 2am on a Tuesday. Didn't tell my wife. Felt almost embarrassed (a 50-year-old man secretly ordering underwear online like it's some kind of indulgence). They arrived Thursday. I wore them Friday. By Sunday she asked if I'd been working out. I hadn't. I just wasn't adjusting, wasn't shifting, wasn't doing that thing men do when nothing fits right. She read that as confidence. She wasn't wrong.
Divorced at 48. Started dating again after two years. The anxiety of someone new seeing you undressed at this age is real. I looked at my drawer faded Hanes from my marriage. That was the first thing I changed. Not for her. For me. Walking into a date knowing that even what nobody sees is handled that does something to how you show up.
You can feel the difference the second you touch them. This isn't cheap satin—it's actual high-grade silk. The stitching is really clean too, no rough edges or cheap elastic. I've had "premium" boxers before that fell apart in 3 months. These feel like they'll actually last.
Found a photo of myself from 7 years ago. I looked... put together. Like someone who thought about the details. I couldn't tell you when I stopped. But that photo made me start again. New haircut, better clothes, these boxers. My wife didn't say a word for two weeks. Then she booked us a weekend away. First time in three years. Coincidence? I don't think so.
I'm 45 and deal with night sweats / hot flashes (yes, men get them too). My wife suggested trying silk and I figured why not. These legitimately keep me cooler—not just marketing BS. I sleep in them now and wake up way less overheated. Also great during the day under trousers. Genuine relief.
Been struggling with boxers riding up for years, especially with my bigger thighs. These stay exactly where they're supposed to. The legs don't creep up and bunch, even when I'm sitting for long periods (which is most of my day). Finally found boxers that work for my body type. Ordered 3 more pairs immediately.
Ordered the black and burgundy to test. Both are identical quality no difference in fabric thickness or softness. The champagne is actually really nice under lighter pants (no show-through). Silk feels consistent across colors which isn't always the case with dyed fabrics. Planning to grab the grey next.
My wife bought these as a "just because" gift and honestly? They make a difference. The cut is really flattering and the fabric has this subtle sheen that looks premium. She definitely approves lol. But beyond that, they're just insanely comfortable for long days. No more feeling gross by afternoon.
Bought these for my boyfriend after he kept complaining about chafing during his bike commute. He was skeptical about silk at first but wore them the next day and immediately texted me "where did you find these??" Now he wants me to throw out all his old ones. The quality is really impressive and they still look new after a month.
I work in sales so I'm in and out of the car constantly. Used to have to adjust my boxers like 20 times a day—super annoying in client meetings. These literally stay in place from 7am to 7pm. Zero ride-up. Plus they don't get that swampy feeling cotton does in summer. Game changer for my job honestly.
I'll admit I was worried about washing silk. Threw them in on cold with my regular stuff (in the mesh bag they include) and they came out perfect. No shrinking, no weird texture changes. I've washed them like 6 times now and they're still as soft as day one. Way easier than I expected.
