SAMUEL P. ★★★★★ - Testi-cool! These are the coolest boxers I've ever owned.

Unlike regular underwear, Stud Briefs provide scrotal support at the same time as cooling. Cool and support improve testicular health and help with the treatment of many scrotal diseases:

IMPROVE TESTICULAR HEALTH
SUPPORT MALE FERTILITY
BOOST TESTOSTERONE
TREAT VARICOCELE & HYDROCELE
ALLEVIATE TESTICULAR PAIN
REDUCE SCROTAL SAGGING
RESTORE ED, PE & LOW SEX DRIVE

LUKAS E. ★★★★★ - Too big of a boost in my sex drive! My sex drive is literally too high now lmao. Insane what a little testicular care can do for you. The best underwear if you care about your balls and T-levels.

Our backers, thank you so much! Our previous Stud Briefs Kickstarter in 2019 350%+ funded, and we fulfilled everyone's orders.

Here is what we're doing that's different from our previous Kickstarter:

Introducing the new Boxer Briefs style. They are much longer, with a fit perfected through 10+ iterations, and it won't ride up no matter what you do (even during exercise)!
No more Boxer Trunks (shorter on the hips and highs)
Re-designed Briefs for significantly better fit, feel, and comfort.
We have adjusted all sizes for a better fit. We listened and understood that the fit of our previous line was too tight. We have now done extensive testing and are standardizing our sizes even more so that your Stud Briefs fit perfectly.
Completely re-designed Briefs Crotch Mesh based on your feedback to bring better support and more comfort
We are making the blue fabric color lighter
Brining out additional sizes: XXS (Kid's size), XS, XXL & XXXL

ERNESTO A. ★★★★★ - Threw out my old undies!!! All 24 of them. Bought 12 new Studs. The support and cooling is just unbeatable. Never going back to regular underwear.

BRIEFS
BOXER BRIEFS
STUDX - ATHELETIC WEAR🔒

MOHAMMAD I. ★★★★★ - Best underwear cool, so I can drive and sit at work without over heating it.

Your normal boxer and briefs trap more than 1.4°C (2.5°F) of heat! This is enough to reduce sperm and testosterone production by over 40%!

Thermal imaging shows Stud Briefs is on average 1.81°C cooler than regular underwear. Stud Briefs technology uses a patent-pending design, cooling mesh, and healthy scrotal support to maximize testicular cooling!

GRAHAM C. ★★★★★ - I highly rate these boxers as someone going through (male factor) fertility treatment. Everything you read tells you to keep your testicles cool and away from the rest of your warm body and these do exactly that. The look and feel of the main boxer material is very comfy.

Testicular health matters. Your testicles are responsible for both sperm and testosterone production.

Sperm counts of Western men have dropped from 337.5 million to 137.5 million since the 1970s. Even more startling is that this decline has no signs of slowing down! Moreover, male fertility is declining globally.

The birth rate of almost every country in the World has been on a decline since 1960. We've been taught about contraception and having babies later and later in life. But, now many of us are aging and worry, "What if it's not possible?

"The biggest problem the World will face in 20 years is population collapse."

- Ellon Musk

In many developed countries, the birth rates are well-bellow population maintenance. A high ratio of retirees to workers puts an increased strain on the economy and disrupts economic output.

Our current lifestyle and environment are hotter than ever before. Heat is a major reversible cause of low sperm and testosterone.

Common Heat Toxic Sources:

Laptops (when used on lap)
Cellphones (in pocket)
Our rooms are now hotter than ever before
Global warming is a significant risk factor
Hot showers, saunas, steam rooms, etc.
Scrotal diseases like varicocele, orchitis, epididymitis, etc.

Common Heat Isolators:

Overweight & obesity
Normal underwear (traps heat)
Pants (especially cargo pants and denim)
Sitting, especially on cushion chairs
Driving (sitting on cushion chair with little or no movement and ventilation)

We are now drowning in more electromagnetic radiation (EMR) than ever before! Many scientific studies show the damaging effects of EMR radiation on sperm count, concentration, motility, and morphology. Moreover, high EMR exposure can also damage sperm DNA!

As a part of our stretch goals, if we hit $40,000, we will build the EMR shielding fabric into the grey color of Stud Briefs. At $100,000, we will use our silver ion technology to add EMR shielding as an option to all Stud Briefs colors.

ERIC G. ★★★★★ - Best underwear I’ve ever worn. I threw out the rest and bought the best! Give these a try.

After receiving a ton of feedback, we re-designed and tested out the Boxer style over 10 times! The new Boxer Briefs style (right side) is longer on the thighs and higher on the waist. It never rides up, and it is way more comfortable than ever before. These are truly the best boxers you'll ever own. We're super excited to get these out to everyone.

THE NEW COOL-BLUE COLOR

We've changed the blue color to be a lighter color now:

COMPLETE RE-DESIGN OF THE MESH

The new Briefs Crotch Mesh is completely re-designed. It is now way more comfortable and provides far superior scrotum and penis separation. Moreover, the support and cooling are still unmatched!

We have sized briefs style much better than before, making them the best briefs that you'll ever own! We are excited for you to get it on!

DAVID T. ★★★★★ - Definitely keeps your scrotum surprisingly cool!

ERIC G. ★★★★★ - Best underwear I’ve ever worn. I threw out the rest and bought the best! Give these a try.

SHANNON B. ★★★★★ - These are a god send for my son. Hes been suffering with serious varicocele pain for years. He wears them everyday and says his pain is down. Thank you and God bless.

GERALD P. ★★★★★ - Excellent. These provide so much relief and significantly reduce my discomfort! I wish I could have bought more, but I could only buy two pairs because of the price.

TOM ★★★★★ - Good style and a comfortable brief. I'm mainly using them for recovery now after my varicocele operation.

SAMEER M. ★★★★★ - It is perfect, would buy more if there is some good discount available.

SAMMY L. ★★★★★ - The Stud Briefs are excellent and they are cool to wear. Very great quality and customer service i think.

JAMES OKAFOR ★★★★★ - The product help with the sagging.. The sagging feel very discomfort . Sir I will recommend you to my cousins and become your representative here in Nigeria.

WILLIE S. ★★★★★ - Good, well-fitting briefs, airy and recommended; that is, unless you leak a little.. Such would be a problem as there isn't enough material to prevent such. Otherwise, it is a very good product.

MOHAMMAD I. ★★★★★ - Best underwear cool, so I can drive and sit at work without over heating it.

ALFRED C. ★★★★★ - Cheers Daniel bought some boxers and they support really well cheers Alfred

ERIC ★★★★★ - Pain has reduced. Delivery was overlooked so make sure to confirm whether shipment has been dispatched to ensure timely delivery. But support was great.

SHENOL A. ★★★★★ - Initially, I have ordered 2 pairs. At the beginning, I was feeling a little bit uncomfortable, but once your body adapts the Stud brief boxer, it becomes as your second skin. The mesh that holds my scrotum a little bit forward is amazing. Every man should wear Stud brief. They are so we'll designed. I have the feeling that they were custom made for me.
