Switched from calvin klein"I used to wear CK for years, but lately it feels like they’re more focused on rainbow drops targeting a different kind of audience, why not just make solid basics. So calvin klein not really my vibe anymore. dumped all of them and switched to stark clean design, no noise, solid fit, much better and cheaper then ck.

5 Stars, very nice fit"Bought one pair just to try. ended up tossing half my old drawer. they’re soft but still feel solid, if that makes sense. waistband doesn’t fold or roll either."

The Waistbands qualitt is impressive"i’m on my feet all day and move around a lot, so comfort matters. most boxers either ride up or start sagging halfway through the day. stark hit the sweet spot — soft, supportive, and doesn’t shift. honestly feels like something designed by someone who actually wears them daily."

The Fabric is the best!"i didn’t think much about underwear before just wore whatever. but after trying stark, it’s hard to go back. the fabric actually stays cool throughout the day, and it doesn’t get that heavy, damp feel cotton ones do. been wearing the boxer briefs under jeans and dress pants, they never bunch or show lines."

"Been lifting for years, most underwear like calvin klein or gymshark either squeezes too much or rides up mid-set. Those just stay put. legit impressed with the cut of the boxers, a bit pricey if you buy singles but if you buy packs it's defo worth it"

Very Nice"i wear suits most days and needed something that doesn’t bunch or show through. Boxer briefs have been spot on the cut is flat and fitted and still comfortable. No adjusting throughout my day. The fabric is incredible, firs time I bought moda underwear and i'm surely not going back to cotton ever again, weirdly enough, they still look fresh after months of wearing and washing. just solid quality without any of the usual branding nonsense, keep it up team stark"

All Day"Wasn’t expecting much, just wanted something that didn’t ride up at the gym. ended up wearing them all the time. Fabric’s so soft and not slippery, waistband has a nice design I like it subtle, and they don’t stretch out like others i’ve had. Might actually replace my whole drawer with these if I win the lottery, lol."

FAQ's
This usually comes down to poor cut and the wrong fabric. Many boxers are either too loose, too short, or made from materials like cotton or nylon that fold and shift with movement. On the other hand, overly long boxers create excess fabric that bunches around the thigh or under shorts. stark boxer shorts are designed with a balanced length and subtle structure to stay in place without squeezing or riding up.
Boxer briefs have a shorter leg and a closer fit around the thigh. They work well under slim pants or suits because they stay flat and invisible. Boxer shorts have a longer leg and a slightly more relaxed fit, which makes them ideal for travel, training, or all-day wear. Both are cut for a modern, athletic fit and designed not to bunch or sag.
We use 95% micro Lenzing™ Modal and 5% elastane. This fabric is noticeably softer and more breathable than cotton, and far more comfortable than nylon blends, which tend to trap heat and moisture. Modal is also antibacterial and moisture-wicking, so it stays fresher throughout the day and keeps its softness after repeated washes.
Yes. Modal is a plant-based fiber that is smoother, lighter, and more breathable than traditional cotton. It is also more durable over time. The specific type we use, micro Lenzing™ Modal, is finer and softer than standard modal, offering a premium feel without being flashy or delicate.
Yes. The longer cut and tailored leg opening of our boxer shorts help prevent ride-up during movement. Whether you are lifting, running through an airport, or sitting on a long flight, the fabric holds without shifting. The moisture-wicking properties also help keep you dry and comfortable under pressure.
There is research suggesting that excessive heat and tight synthetic fabrics in the groin area may negatively affect testosterone levels and fertility over time. That is one reason stark avoids synthetic-heavy blends like nylon. Our modal fabric breathes well and maintains airflow without compressing or overheating sensitive areas.
Stark underwear is designed to hold its shape and feel after 50+ washes. Modal is naturally resilient, and the waistband is built to stay flat without curling or stretching out. The fabric does not pill, fade, or become rough over time, which is a common issue with cotton underwear.
If you are between sizes, we recommend sizing up. The fit is true to size, but modal does not compress like spandex. It has stretch, but the waistband is firm and supportive. Sizing up provides more comfort without losing structure. You can find the Size Guides on the product page for more info.
Yes. Boxer briefs are especially good for wearing under slim pants because of the tighter leg opening. Boxer shorts work well under looser clothing or during activities, but both are designed with a clean, minimalist fit that avoids bulky seams or logos that show through.
We offer a 60-day money-back guarantee. If you get a hole, do not like the fit, or simply change your mind, you can return them within 60 days for a full refund. If you ordered the wrong size, we are happy to exchange it as well. No hassle.
