Modal vs cotton underwear

Compared with cotton, modal underwear typically feels smoother, drapes more closely to the body, and stays softer after repeated washing. Cotton feels more matte and structured. If softness and a smooth, lightweight feel matter most, modal is the better choice.

FAQ

What is modal fabric?
Modal is a soft fabric made from cellulose fibers, typically from beech tree pulp. It is a type of rayon, a plant-based fiber that is processed into yarn. Modal is known for being smooth, lightweight, and breathable, and for holding its softness wash after wash, which is why it is often used for underwear and loungewear.

Is modal good for underwear?
Yes. Modal is soft, smooth, and breathable, which makes it a popular choice for boxer briefs you wear all day.

What does "60s yarn" mean?
It is the yarn count. A higher count means a finer yarn, which produces a thinner, smoother fabric. It refers to the fabric, not the number of pairs.

What sizes are available?
S, M, L, XL, and 2XL. See the size chart to find your fit.

What are these boxer briefs made of?
92% modal and 8% spandex.

Why We Made This

There was a moment I realized clothing was the problem.

Not the weather.

Not the room temperature.

The fabric itself.

I was constantly overheating — especially in underwear that trapped heat and held moisture against my skin. The discomfort became so normal that I caught myself doing something without even thinking about it:

Pulling the fabric away from my skin just to let air in.

Again and again throughout the day.

At work.
At home.
Trying to sleep.

That small movement became a habit — a constant attempt to create space, airflow, relief.

Like most people, I tried cotton first.

But traditional cotton underwear absorbs moisture and holds onto it. Once heat and sweat build up, the fabric becomes heavy, damp, and warm against the skin instead of cooling you down. Even when cotton feels soft at first, it often loses breathability throughout the day.

For someone who overheats easily, it simply wasn’t enough.

If you’ve ever found yourself:

  • pulling fabric away from your skin,
  • overheating while sitting still,
  • waking up sweaty at night,
  • or constantly adjusting throughout the day…

there’s a good chance your underwear is trapping more heat than releasing it.

Cotton has been the standard for years, but “normal” doesn’t always mean comfortable.

Your body naturally creates heat. Your underwear should help release it — not trap it.

Shorts helped temporarily, but then my knees would ache from cold air. Long pajamas felt suffocating after only a few minutes.

Nothing felt balanced.

So I became obsessed with finding better fabrics — materials that actually worked with the body instead of against it.

That search led me to modal.

Modal is a plant-based fabric made from beech tree pulp, known for being exceptionally soft, breathable, lightweight, and moisture-friendly. Unlike traditional cotton, modal stays smoother, cooler, and drier against the skin throughout the day.

To make it even more breathable, we paired it with a lightweight mesh construction engineered to maximize airflow and reduce heat buildup where it matters most.

The result is this Mesh Modal Boxer Brief.

Soft enough for everyday wear.

Breathable enough to stay cool.

Lightweight enough to forget it’s even there.

Once you experience the difference, it’s hard to go back to cotton.

Because comfort should never require effort.

Why We Made This

If your boxer briefs constantly ride up, one reason could be that you picked the wrong size.

But even with the right size, most boxer briefs still creep upward throughout the day.

A better solution — and probably the real solution — is simply going longer.

That’s where long boxer briefs changed everything for me.

The extra length helps prevent the fabric from rolling upward on your thighs, reducing friction, bunching, and the constant need to adjust throughout the day.

Because once you notice ride-up, you can’t stop noticing it.

Walking. Sitting. Working. Traveling.

Pulling the legs back down becomes automatic.

I realized I was adjusting my underwear almost as much as I was wearing it.

But most long boxer briefs had another problem:

They felt too heavy, too hot, and too restrictive.

Traditional cotton trapped heat and moisture, especially with extra fabric around the legs. What should have felt supportive ended up feeling damp, bulky, and uncomfortable after a few hours.

So we designed something different.

A seamless long boxer brief built to stay in place without feeling tight or suffocating.

What makes it different starts with the construction.

Traditional underwear is made by stitching multiple fabric panels together, creating seams that can rub, dig into the skin, leave pressure marks, and create friction throughout the day. Seamless construction minimizes those bulky stitched areas, creating a smoother, cleaner fit that feels lighter and more natural against the body.

Then there’s the fabric itself.

We chose a premium viscose blend because of how soft, breathable, and lightweight it feels on the skin. Viscose is a plant-derived fiber made from natural wood pulp and known for its silky smooth texture and cooling comfort. Compared to traditional cotton, it feels softer, drapes better, and allows heat to escape more easily throughout the day.

Combined with natural stretch, the fabric moves with your body instead of fighting against it.

No bunching.

No rolling.

No stiff seams.

No constant adjusting.

Just lightweight support, breathable comfort, and a smooth fit that stays comfortable from morning to night.

The result is our Seamless Long Boxer Brief.

Designed for men who want longer coverage without extra heat.

Support without restriction.

And underwear that finally stays where it’s supposed to.

Because the best underwear is the kind you stop noticing the moment you put it on.
