Shop Modal Boxer BriefsWhy underwear fails
The discomforts most men just learn to live with.
Most underwear problems are small at first, then they keep showing up every time you sit, move, sweat, or try to get through a long day.
Heat + sweat
Everything feels heavier in the heat
When fabric traps moisture, comfort disappears fast and the fit starts to feel sticky.
Movement
Ride-up and readjusting
The worst pairs keep shifting, rolling, or bunching every time you move.
Feel
Soft at first, rough by noon
Many basics start decent but lose their smooth feel after a few hours of wear.
Enter Micro-Modal.
The Ultimate Upgrade.
We engineered the dllllb briefs with premium Micro-Modal because your comfort shouldn’t have an expiration date. It is definitively 3x softer than cotton, insanely breathable, and wicks away moisture before you even feel it.
Silky Smooth & Shape Retaining:
Never loses its stretch or softness, wash after wash.
Temperature Regulating:
Keeps you cool when it’s hot, and comfortable when it’s not.
Distraction-Free Design:
We eliminated the useless pockets, removed the scratchy waistband logos, and kept only pure, clean support. Just you and a perfect fit.

Softness that survives laundry.
Finally, no mid-day readjusting.
The modal feels cool right away and the legs stay put through my commute and office day. I ordered the 6-pack after the first wash.
Soft without feeling flimsy.
I was worried they would be too thin, but the support is clean and the waistband does not dig in. They feel premium, not delicate.
The hot-weather pair I needed.
Cotton used to stay damp after walking outside. These dry faster and do not get that heavy sticky feeling by the afternoon.
Fit & Care
Everything you need to know.
Find your size, understand the fabric, and get answers before you buy. No guesswork, no surprises.
Sizing & Fit
How do I choose the right size?
Measure your natural waist at the narrowest point (usually just above the navel). Compare your measurement to the size chart. If you're between sizes, go with the larger size — the modal fabric has 4-way stretch and will conform to your body without feeling tight.
Do these run true to size?
Yes. Our fit is designed to feel snug but not compressive. The modal blend stretches with movement and recovers its shape, so you get consistent support without sizing up.
What does the 6-inch inseam mean for fit?
The 6-inch leg extends to mid-thigh, which prevents ride-up and reduces skin-on-skin friction. It's long enough to stay anchored but short enough to remain invisible under slim-fit pants or shorts.
Fabric & Care
What is Lenzing Modal and why does it matter?
Lenzing Modal is a fiber derived from sustainably harvested beechwood. It's 3x softer than cotton, naturally moisture-wicking, and retains its softness wash after wash. The 100S grade we use is the finest available.
How should I wash these?
Machine wash cold with like colors. Tumble dry low or hang dry. Avoid bleach and fabric softener — the modal fiber is already naturally soft.
Will they shrink or lose shape over time?
No. The nylon and spandex in our blend provide structural recovery that cotton can't match. After 50+ washes, the fit and softness remain consistent.
