Engineer’s Notes

The most technologically advanced underwear ever built. The Apex III Series features the updated Paradise Pocket Gen III ball pouch that's built with spacesuit-grade materials and category-leading tech for an incredibly comfortable wear. 

First, we reinvented the Paradise Pocket with the updated Gen III design - it's even easier to put on and you'll never fall out of the ball pouch, so the twins will never stick to your thighs again. No more awkward sumo squat, elongated side step or bat wings (sorry for the visual) - just life-changing comfort and adjustment-free days.

The silver fabric used in the Paradise Pocket Gen III has incredible anti-odor properties and permanent anti-odor control. The silver in the fabric kills 99.9% of odor-causing bacterial so you can travel light and extend the time between washes while your genitals stay fresh.

The Paradise Pocket Gin III's fabric is also anti-radiation - by using it to form the Pocket, it creates an anti-radiation Faraday Shield to protect your "boys" from harmful, sperm-killing electromagnetic waves emitted from electronic devices - it's the same fabric tech used in spacesuits. The 3D pocket design blocks electromagnetic waves from your majesticles from all angles - phone in pocket, laptop on lap, wifi router nearby - all blocked with full protection from any direction.

The rest of the Apex III underwear is made with our EcoSilver performance fabric that is designed to deliver peak performance with a lower environmental footprint. We spent over a year developing a custom recycled, premium-grade yarn that maintains the same performance features and ultra soft feel you’ve come to know and love.

Then, to push fabric innovation further, we combined the recycled yarns with metallic silver to give you extraordinary next-to-skin comfort and the very best odor protection. Silver is the most effective material for neutralizing odor-causing bacteria and is advanced enough to be used in spacesuits to keep astronauts fresh.

Apex III is engineered with 15+ smart features, including Power Grip, laser-cut wide leg grippers lined with soft silicone for incredible hold. The legs will never ride up or bunch, so no more awkwardly tugging your pants to pull the legs down. The Power Grip is also stays hidden, even under tighter pants, so no more visible underwear lines either.

Very nice

Very comfortable, best pouch of all that I have tried.

Very happy, best underwear ever!

I just got them and I have just washed one of them once (so still need to check how durable they are) but they are the most comfortable, convenient and even good looking trunks I have ever worn. It is noticeable the technology they talked about on the specs. They certainly fulfil all needs for a underwear. I train every day at the gym are they are also perfect for that. I will need to tray them when playing football but I believe they will perform excellently as well.

Streamlined!

Thoughtful aspects for each part of the underwear. The pouch captures easily as well.

I was given these by my wife. Quickly became my favorite

K
Kuppa (United States)
Comfortable!

Switched to all citizens about a year ago, it was the best decision I could have made. They fit great and are super comfortable!

D
David W. (United States)
Restrictive

Good quality, very comfortable, I like that the legs don’t ride up. But the front pouch is very restrictive you should offer a couple options in the size of the pouch. If you did I would buy multiple pairs but Because of this I wouldn’t purchase again

D
David B. (United States)
Great

Fits comfortably and doesn't ride up

Durable and Comfortable

Have been hunting for durable underwear that is both comfortable and cool. I had preferred the loose fit of boxers, but grew tired of how difficult it was to get dressed in the morning and how they would bunch throughout the day. These briefs help me stay cool and my wife thinks so too.

Greg T. (United States)
Best Underwear Ever

These boxer briefs are perfect. The most comfortable pair I’ve ever owned. Can’t wait to get more.

Great

Was skeptical at first. Wasn’t sure if I’d like the design so ordered one to try. Definitely liked them and am ordering more!

M
Mario G. (United States)
Great Support

Very comfortable and breathable! I love that they don’t ride up and that I don’t have to constantly be adjusting the boys. I bought one pair to begin with and am currently like 10 pairs deep. No joke.

Best underwear yet!

I've tried the model before these and you had to lift the boys into the pouch, these ones they just fall right into place!!

Buy these, NOT the Elite style

I bought multiple Elite Style and one Apex style on my initial order. Within four months, ALL of the Elite had holes, but the Apex were fine (they have a different material/weave than the Elite). All Citizens sent me three more Apex for free, when they saw my review of the Elite and those are all still going strong, so I bought one more pair of the Apex. So far, zero issues with any of the Apex and they are very comfy. So, if you are going to buy any boxer briefs from these guys, I'd get the Apex.

Best boxers

I’m very impressed! Super comfortable and well designed. I will be ordering more.

Good stuff.

Bought couple pairs of the trunks a while back, moving other brands out of the bureau to make room for newer and more citizens brand. For is good, quality ok. I just like the feel of these vs other brands. They keep the toys where the tools need to be kept.

A
Alex R. (United States)
Best boxers ever!

I usually have issues with sweat and smell. No more with these amazing underwear. Love them!

D
Devin E. (United States)
Great underwear!

The gripper and pouch both work very well. Can't say I really notice a difference between this tier and the elites tho.

P
Patrick W. (United States)
Never wearing anything else again!

I am a firefighter paramedic and I also own a property maintenance business. I have tried every kind of underwear you could think of! I can say with confidence the apex 3 trunk underwear are the most comfortable underwear in the world!

A
Andrew B. (United States)
Super comfortable

They have been great and incredibly comfortable to wear

J
Jon (United States)
Good quality

The leg grips take time to get used to but after the initial weirdness they stay put and are really much more comfortable

J
Joseph K.
Best ever

These are life changing!
I’ve tried several other brands and they don’t come close to keeping you cool and collected

Apex III Longer Boxer Brief

David (United States)
The comfort is there

I've been looking for a boxer that doesn't give me the urge to adjust myself constantly. I finally found them

D
Daniel A. (United States)
Very well considered

If I was still 265lb I think these would be too tight on me even at a larger size, that’s my history with tech boxers like this anyways. But now that I’m 200lbs these are great. They hold the family in the most comfortable way compared to other brands that have a family pocket up front. They have the best flap for taking a pee. The leg sticky part keeps them in place. Only test I haven’t done is one of my backpacking trips to see how may pairs I’d need for a week. Hopefully antimocrobial af so they don’t smell too bad. Would be fun to get a merino version of these. Anyways they are a nice product and I’d reccomend.

Wow

Never knew underwear could be this comfortable

J
Jovanni F. (United States)
I've been missing out!

I saw the ad a few times on social media and figured to give it a shot. I can't remember the last time I bought underwear, but I knew the current undies required readjustments throughout my day. The Apex III is my solid solution. Once on dingle and dingle berries are in position. Goodbye discomfort.

Awesome underwear

They are very comfortable and they don’t ride up so I would definitely recommend them
