Premium singles run $32–$38 a pair.
Runs true to size Size chart
Four interlocking stitch points eliminate ride-up and bunching. No tug. No shift. No single-stitch failure point.
Independent support structure ends skin-on-skin friction and heat buildup. Built around how men actually move.
Dual-layer internal stiffening holds position through long days and demanding movement. Sits where you put it.
Three distinct weaves mapped to specific heat zones. Targeted airflow where you run hot, structure where you carry load.
The soft-luxury brands nailed the fabric and stopped there. The big-box brands built tough and skipped the comfort. RNWL runs the same premium modal at 89%, then spends the construction budget where they don't: four stitch points at every hem, a dual-layer band, three mapped fabric zones. Built for a full year of daily athletic use.
- Quad-Locked Hems vs. single-stitch failure on every competitor
- Anatomical Separation Pouch vs. flat construction that crushes and chafes
- Zero-Roll waistband vs. elastic that rolls after 3 washes
- Cost per day: $0.08 vs. $0.19 for pairs replaced every 6 months
- Free U.S. shipping on 4-Packs, 8-Packs and bundles · 2-Pack ships for $8.95
- Ships within 24 hours, arrives in 2–4 business days
- 365-day performance guarantee. If it fails, we replace it. No forms, no fighting.
- Free return shipping on manufacturing defects only
- 89% modal, 11% spandex. Modal gives you the hand feel of a premium performance fabric without the synthetic grip of a cheap athletic blend. Spandex locks structure and holds fit wash after wash. No stretch-out, no sag, no loss of shape over a year of daily use.
- Machine wash cold, tumble dry low
- Do not bleach or iron directly on fabric

"Great comfort and fit. Found RNWL after Lululemon and switched immediately. Great for sensitive skin, no more chafing."
"Worth every penny. I never go without them. Comfortable and breathable. Only wish they came in more colors."
Every first order is covered. Wear a pair for 30 days, and if they are not the best underwear you own, we refund you in full. Send back the unopened pairs on our label. On a 2-Pack, keep them.
"The waistband doesn't move. I didn't realize how much mental energy I was spending adjusting until I stopped having to."
"Bought a pair for my husband and he won't wear anything else now. No annoying tags, fit runs true. Took off a star only because shipping took a few extra days."
"Definitely will buy again. Very comfortable, easy fitting, invisible feel. More comfortable than cotton."
"Comfortable to wear. I forget I have them on. These are the most comfortable underwear I have ever tried."

the objections.
"It's more expensive than what I'm buying now."
Your $4 pair is cheap until you count the adjustments. Your $35 pair is premium until the band rolls. RNWL runs $12 to $14 a pair, guaranteed in writing for 365 days of daily use. Check your drawer for another brand that signs that.
"Synthetic fabrics feel cheap and plasticky."
This is 89% modal, the same fiber the $36-a-pair brands build on, at 11% spandex for structure. The difference is what surrounds it: four stitch points at the hem and a dual-layer band, so the softness survives the year instead of the season.
"The elastic always ends up rolling and poking through."
That happens when a rubber band sits in a single-stitched sleeve. Quad-Locked Hems brace four interlocking stitch points and the band runs dual-layer. No single failure point. That construction is why we can back it for 365 days.
"What if it doesn't fit right?"
Match the size guide and the fit works. If it still isn't right, the 30-Day Fit Promise covers your first order: not the best pair you own, email us for a full refund. Open one pair, send back the rest unopened, we pay the shipping. Manufacturing defects stay covered for the full 365 days.
365-DAY

GUARANTEE.
If a seam, waistband, fabric, or hem fails inside 365 days, we make it right. No forms. No fighting.
