The real cause

Your chafing isn't coming from your skin.
It's coming from the wrong pairing.

It's not a sweat problem. It's a loop: wrong fabric, wrong cut, moisture builds up, friction starts, you re-adjust every hour. We call it the Hot-Friction-Damp Loop™. Once you name it, you can fix it.

01

Wrong fabric

Cotton holds moisture, synthetics don't breathe. Both work against you, especially after 11am.

02

Trapped moisture

Sweat sits. Skin heats up. Friction starts. It's mechanical, not hygienic.

03

Ride-up & chafing

The boxer rides up, rubs the thighs, marks the waistband. By 4pm it's all you think about.

04

You re-adjust

15 times a day. The loop repeats. 11 years on average per a British study cited by Esquire.

COMFORTCORE™

Our solution

The pairing that breaks the loop: long-fiber bamboo + a cut that stays in place.

Not a technical boxer. Not an eco boxer. Both. The softest fabric we could find, cut to never move again.

96% long-fiber bamboo

Viscose woven from extra-long fibers: second-skin softness, less pilling, better skin tolerance. No short-shred bamboo, no marketing trick.

Targeted AirMesh™

Vented panels placed only where heat builds up. Moisture is wicked away before it turns into odor or irritation.

ComfortLock™ waistband

Thick elastic that holds without doubling up. Stays in place all day. No marks under your shirt.

Anti-ride-up patterning

The cut is tested in regular and Long-Leg fits. No more riding up during a squat or a long sit.

Flat seams · printed label

Zero scratching, zero itching. Built for sensitive skin and regular skin alike.

Who it's built for

Three men. Three problems. One root cause.

We sat down with the ORION team and three customer profiles. They told us what nobody else really serves well.

PROFILE 01 Bureau

Jean-Pierre, 45 ans

Cadre DSI · PACA · 70-75 kg · costume-cravate semaine

« Je cherchais un boxer que j'oublie au bureau. Porté à 21h sans avoir touché son boxer de la journée. »

Pour Jean-Pierre, on a optimisé la respirabilité bureau et la ceinture ComfortLock™ qui ne marque pas la chemise.

Recommended ORION ComfortCore™ · Pack Semainier 7
PROFILE 02 Sport

Marc, 38 ans

Runner · Lyon · 3-5 séances par semaine · costume au taf

« J'avais un dilemme : si je choisissais un boxer sport, j'avais une coupe inconfortable. »

Pour Marc, la version Long-Leg coupe les frottements cuisses à 20 km, et le bambou évite l'odeur synthé-après-sport.

Recommended ORION ComfortCore™ · Long-Leg · Duo Sport
PROFILE 03 Peau sensible

Paul, 40 ans

IT · Lille · antécédents eczéma réactif aux teintures et élastiques

« Une crise d'eczéma pour un élastique mal taillé ? Pas merci, je veux du transparent. »

Pour Paul, composition claire 95% viscose de bambou + 5% élasthanne, coutures plates, étiquette imprimée, et essai porté 45 jours.

A word from the founder

« I spent two years re-adjusting my boxer between 9am and 6pm. I figured a few million of us were doing the same without talking about it. ORION was born exactly from that frustration: a product you forget you're wearing. If we miss the mark, we refund — I insist on that. »

— Lucas D., founder · 2023

Frequently asked

Straight answers.

Why bamboo rather than organic cotton?

Cotton holds moisture up to 27% of its weight before releasing it. Long-fiber bamboo wicks it away. Over 11 hours worn, it changes everything: skin stays dry, friction never starts, you forget you're wearing underwear.

Is it really bamboo or bamboo viscose?

Long-fiber bamboo viscose, at 95%. The raw fiber is cellulosic, so it goes through a chemical process to become textile (like linen, silk). At Orion: long-fiber viscose = durable softness, OEKO-TEX® Standard 100 certified. We don't sell short-shred bamboo in disguise.

Which size if I'm between two?

Take the smaller size. The ORION cut has 5-8% more stretch than the average — it adjusts without squeezing. If in doubt, we exchange free twice.

How do I wash it?

Machine wash 30°C, inside out, in a mesh bag if possible. No tumble dryer, to protect the elastane. Washed like this, the boxer holds its shape for at least 18 months (tested in-house over 200 cycles).

What if it doesn't fit me after 45 days?

You send it back, we refund everything. No conditions. No need to be unworn — you wore it, that was the point. It's the only way to be sure.

Where is it made?

Weaving and finishing in Turkey (Izmir) at a partner workshop we audit twice a year. The fiber comes from China (Sichuan) — there's no European production of weavable bamboo to date. Packing and customer care from our EU operations team.
