0% Polyester
No electrostatic field
Cotton-led woven poplin removes the electrostatic charge generated by petroleum-based fibres against skin.
Pelvic wellness, engineered.
The boxer designedaround your microclimate.
A 3D-engineered overlap fly. A skin-safe tunnel waistband. Roica™ V550 biodegradable stretch in 95% organic cotton poplin. Built to keep you cooler by 0.7°C where it matters.

Visualization — airflow channels through the engineered fly.
The Triple Zero Standard
A new specification for what touches you all day.
Most performance underwear optimizes for compression. We optimize for what your body removes from circulation: synthetic polymers, hardware contact, and trapped heat.
0% Buttons
Anatomical comfort
A 3D-molded overlap fly replaces hardware. Zero pressure points across the inguinal region during long wear.
0% Microplastics
Roica™ V550 biodegradable
The first elastane verified to biodegrade in marine and sludge conditions, integrated at 5% for skin-safe stretch.
Clinical Proof Dashboard
Designed against scrotal hyperthermia.
Sustained heat above 35°C disrupts spermatogenesis. The Wellness Boxer was engineered to keep the inguinal microclimate measurably below it — without compression and without polyester.
How we measured
Engineering data, controlled conditions.
- Benchtop thermography against a body-form simulator at 35°C ambient.
- Body-equivalent humidity (~60% RH) and 10-minute thermal equilibrium.
- Standard polyester boxer briefs as the control garment.
- Mean delta of repeated trials, reported to one decimal.
This is engineering evidence of design intent. It is not a randomised clinical trial and we do not extrapolate fertility outcomes from it. See the Science page for the full method and citations.

Higher sperm concentration
Observational data has linked loose-fitting boxers to a 25% greater sperm concentration vs. tight, polyester-heavy underwear.

Scrotal cooling benefit
Replacing tight synthetics with airflow-channelled cotton consistently lowered surface scrotal temperature by ~0.7°C in benchtop thermography.

Effective ventilation
The 3D overlap fly + crisp poplin weave produced a 99% effective ventilation rating in repeated airflow trials at body-equivalent humidity.

Material Traceability
Two materials. Verified to the fibre.
Tunnel Waistband
Skin-safe by construction.
The Roica™ V550 elastic core runs inside a fabric-encased tunnel of organic cotton. There is no rubber, no logo print, and no synthetic surface against your skin — even where the band sits all day.
- 0% synthetic contact at the iliac crest
- Roica™ V550 core, biodegradable elastane
- 95/5 organic cotton blend woven sleeve
The Poplin Weave
Crisp, dry, and structured.
A 95% organic cotton crisp poplin paired with 5% Roica™ V550 elastane. The structured weave creates the airflow channels you saw above, without the cling of jersey.
- OEKO-TEX® Standard 100 verified
- GOTS-eligible organic cotton supply
- Marine + sludge biodegradation verified for the V550 core
Crafted in Portugal
Barcelos textile hub. Premium quality, ethical labor.
Each pair is cut and sewn in our Porto-area facility on the same high-precision lines used by leading European wellness apparel brands. Roica™ V550 bio-stretch is integrated through a documented seam protocol — no logo print, no plastic tags, no animal-derived adhesives.

Active recovery guide
When to wear loose. When to wear tight.
Compression is a tool. So is airflow. Both have a place — but they are not interchangeable, and most men spend 90%+ of their day in the wrong one.
Wellness wear
Daily, sleep, post-workout cooldown
Loose airflow, biodegradable stretch. Optimised for thermoregulation and minimum mechanical contact.
Wellness Boxer (this product)
Compression
Heavy lifting, contact sport, torsion-risk activity
Use a dedicated compression short for athletic torsion protection. Compression is for the gym, not the office.
Not what we make. Use a sport-specific brief.
