Oh very nice fit also for guys! I like the smaller backside and seam up the middle gathers for a better fit. I will buy them again in other colors!

What we obsess over
BreathableMade from bamboo-derived rayon, a fibre that naturally breathes.
StretchA deliberately low 9% elastane, the right amount of give without turning the fabric synthetic.
Moisture-awareRayon moves moisture better than untreated cotton.
Second-skinCut close, sits flat, disappears under clothes.
Soft handBamboo rayon fibres are naturally smooth and round, silky without added softeners.
PreshrunkWhat you order is what you keep, wash after wash.

We pick the best materials we can source and preshrink the fabric so it lasts for the longest possible time.

Built-in Features ENGINEERED FOR DAILY WEAR
COMFORT
Flat-lock back seam
The only visible seam runs across the back, flat against the skin, doubling as a design detail.
FIT
No side seams
Nothing presses into your hips or breaks the line, it just wraps clean and feels better.
HYGIENE
Double-layer gusset
A second layer of the same rayon fabric for extra coverage and everyday freshness.
RANGE
One fabric, every cut
Briefs, boxers, boy briefs and thongs, all cut from the same ribbed knit.
TEXTURE
Ribbed knit
The rib adds natural flex and a touch of airflow, and looks as good as it feels.
LABEL
Tear-away tag
Peels away cleanly by hand, no scissors, no risk of nicking the fabric.
