Product Insights
This boyshort offers a barely-there feel with TENCEL modal that wicks moisture 60% faster and absorbs 50% more than cotton, retains softness and resists pilling, and provides stretch recovery to prevent ride-up and sagging, though the waistband rides up on shorter torsos and the fabric relaxes after several wears, offset by a low cost-per-wear from bundle pricing and Reddit endorsement.
Verified claims
- Rear coverage
- Boyshort cut provides bikini-like coverage, not full seat coverage.
- Waistband height
- Waistband rides up to the breastbone on shorter torsos.
- Tummy accommodation
- Stretchy fabric accommodates a belly without rolling down.
- Fit
- Buyers report comfortable tummy coverage for fuller midsections, but ride-up for shorter torsos.
- Softness
- Modal fibers are half the diameter of cotton and wick moisture 60% faster for a dry, barely-there feel.
- Durability
- TENCEL modal retains its softness through many washes and resists pilling far better than cotton.
- Breathability
- Buyers report the ribbed TENCEL blend stays cool and breathable all day.
- Moisture wicking

- Wet strength
- Modal retains 90% tensile strength when wet, while cotton loses 25%.
- Barely-there feel
- Buyers report the lightweight, stretchy fabric feels barely there.
- Stretch recovery
- Ribbed knit expands with movement and snaps back, preventing ride-up and sagging.
- Panty line concealment
- Ribbed texture scatters light to minimize VPL under close-fitting trousers.
- Shape retention
- Buyers report that the fabric relaxes and loses supportive fit after several wears.
- Value tradeoff
- Low cost-per-wear (~$8/pair in 5-pack) offsets limited shape retention.
- Pricing

Very nice but fit poor
This bra is very soft and I love how it feels on however after wearing it for a little while the bra rides up . It goes up onto the bottom of my breasts and then uncomfortable
Très confortable
J'adore! Je prévois en commander d'autres
Perfection
J’en prendrais de toutes les couleurs, mais il n’y a que gris! Super confortable, tombe bien!
Raffiné mais…
Le tissu est un peu lâche avec le temps.
