Built for the road.
Not the gym.
Built for drivers who can't step out of the chair — 14-hour shifts, not 45-minute workouts. Keeping you comfortable from the first mile to the last.
No more swamp ass
Bamboo-modal blend wicks 3× faster than cotton. Antimicrobial-treated fabric resists odor between washes.
Zero ride-up
The 8″ inseam stays locked through a 14-hour shift and every climb out of the cab.
Pouch support, not pancake
A 3D separation panel keeps everything off the seat. You stop sitting on yourself.
Minimum readjusting.
The 8-inch inseam lands below the thickest part of your thigh — exactly where ride-up begins. A soft silicone grip band keeps the hem locked without squeezing.
Walk the dock, climb the cab, sit for six hours straight — they stay where you put them.
Dry feel. All shift.
65% bamboo viscose / 28% modal / 7% spandex — a blend that wicks moisture away from your skin and dries fast, without the plastic-bag feel of cheap synthetics.
Cotton holds sweat against you for hours. This moves it out.
Your belt fights your waistband. We ended that fight.
A 2-inch wide waistband distributes pressure evenly, sits flat against your skin, and refuses to roll or fold — no matter how long you sit or how tight the belt.
Designed for work pants, not gym shorts.
Cut for the thigh, not just the waist.
| Size | Waist | Weight |
|---|---|---|
| L | 34–37″ | 190–220 lb |
| XL | 37–40″ | 220–250 lb |
| 2XL | 40–44″ | 250–285 lb |
| 3XL | 44–48″ | 285–320 lb |
| 4XL | 48–52″ | 320–360 lb |
| 5XL | 52–56″ | 360–400 lb |
| 6XL | 56–60″ | 400–440 lb |
Fit notes
These run true. If you're between sizes, size up — the grip band needs space to work without squeezing.
Full size run to 6XL (60″ waist). Order by your work-pants waist, not your t-shirt size — we cut for thigh, not just waist.
Athletic build with bigger thighs (lifters, cyclists): size up one for room through the leg.
What drivers say after a week on the road.
Not all boxer briefs handle a 14-hour shift the same way.
