  • "Forgot I had them on through a 12 hour shift"

    I'm an electrician, up and down ladders from 6am. By lunch my old boxers had me raw and sticking, worse in summer. First day in these I genuinely forgot I was wearing anything. No chafe, no swamp, cool the whole shift. Bought three more pairs that weekend. - Mike, 41

  • "The burn spots are just gone"

    I drive for a living, ten hours in the seat plus loading and unloading. Every summer I'd get that raw burning patch on the inside of my thighs. Switched to these on a buddy's word. Two weeks in, nothing. No burn, no stink, and they don't ride up when I'm in and out of the truck all day. - Carlos, 34

  • "Thought silk was a soft guy thing. I was wrong"

    Almost didn't order. Silk underwear sounded like something for a different kind of guy. But I work a hot kitchen and I'm soaked through by the dinner rush. These breathe like nothing else I've worn. Dry, cool, no stick. I'm not putting plastic back on. - Dave, 52

Our Boxers

Pure silk boxer briefs built for men who are on their feet all day, not posing for a photo. Silk is the original performance fabric, what fighting men wore against their skin for a thousand years, because it breathes, pulls sweat off the skin, and slides instead of grabbing. Cut to stay put through a full shift with no ride up and no bunching. The result is simple. No chafe, no swamp, no plastic against the warmest part of your body all day.

Fabric & Care

Made from [100% mulberry silk], a natural fiber, not the nylon and polyester blend most underwear hides behind. Silk breathes, wicks moisture, and is naturally gentle on skin, so it won't saw you raw the way synthetics do. Care is easy. Machine wash cold on a gentle cycle, ideally in a mesh laundry bag. Skip the dryer and lay flat or hang to dry. No bleach, no softener, no ironing. Treated right, a pair holds its feel for years.

When to Wear?

Every day, but especially the days you move. Long shifts on your feet, hot summers, long drives, travel, the gym, any job where the old stuff starts sawing by noon. If you spend your day standing, lifting, driving, or walking, this is the layer that decides whether you finish the day comfortable or raw.

Shipping & Guanrantee

Most orders arrive within 5 to 8 business days.

Your first pair is backed by our 30 Day Fit Guarantee. Wear them. Wash them. Walk a mile in them. If they don't deliver on every promise we made, send them back for a full refund. No awkward questions.

Our Boxer Briefs

Safe Your Balls

Support where you need it and airflow where it counts. The warmest part of your body finally breathes instead of cooking inside a plastic seal, so the heat and the swamp never build. Cooler, drier, held in place through the whole shift. No digging, no rolling, no reaching down to fix them.

Our Boxer Briefs

No Micro Plastic

Most underwear is plastic. Nylon, polyester, elastane, all petroleum spun into thread that traps heat and sheds microplastic against your skin sixteen hours a day. Strides is silk, a natural fiber that breathes, wicks, and leaves nothing synthetic against the one place you don't want it. Pure, the way men wore it before plastic took over the drawer.

Your Body Deserves More Than "Just Deal With It"

Backed by real men

92%

Reported zero chafing after a full day on their feet, even in summer heat.

90%

Said the raw thighs and burn spots they'd put up with for years finally stopped.

96%

Say they'll never go back to plastic underwear again.

Made for Every Man. On Every Shift.

Whether you're framing a house in July, behind the wheel for ten hours straight, or just sick of peeling your shorts off your skin by noon, Strides meets you exactly where you are.

Chafe doesn't discriminate. It happens to electricians and truckers, to the guy on the line and the guy standing at the counter all day. It happens in ninety degree heat and it happens under jeans. And for too long, men have been told to just deal with it. To powder it. To shift around it. To tough out the whole shift raw.

Strides was built for real men doing real work. Men who don't get to sit down. Men who want to walk further, stand longer, and finish the day without thinking about their thighs once. Every trade, every season, every shift.

Lightweight. Breathable. Built to last. No matter how many summers you've spent toughing it out, it's not too late to get out of plastic and into silk.

Spend half my day bent over engines in a garage with no AC. Used to be soaked and chafed by noon. These keep me cool and dry through the whole day. Don't even notice them anymore.

Luis M.

I do twelve hour shifts at the hospital, mostly on my feet. By hour eight my old underwear had me raw. First week in Strides and that stopped. Comfortable from clock in to clock out.

Devon R.

Wore a pair under my suit at my brother's wedding in July. Outdoor ceremony, brutal heat, and I was the only groomsman not shifting around miserable. Sold.

Aaron T.

I deliver mail and walk my whole route. Summer used to mean rubbing raw in places I won't name. These glide instead of grab. Best money I've spent on anything for work.

Frank D.

Run a small farm and I'm outside sunup to sundown. Sweat, dust, heat, all of it. First pair that doesn't turn into a swamp by mid morning. Bought more for my son who helps out.

Wade H.

Did a six hour ride on the bike last weekend. Normally I'm peeling myself off the seat at every stop. Rode the whole way comfortable for once. Staying in the rotation.

Kyle B.

I'm a big guy and my thighs have always rubbed raw no matter what I wear. Tried every powder and long boxer out there. These are the first that actually fixed it. Almost can't believe it.

Marcus J.

Bought these while recovering from surgery when everything felt irritating against my skin. So soft I barely felt them. Kept wearing them long after I healed. Now they're all I wear.

Gerald P.

I sweat more than most guys and it's always been a thing for me. These don't stop the sweat but they handle it. Dry, cool, no smell at the end of the day. First time I've felt normal in years.

Tony S.

Threw out every old pair I owned after a week in these. No regrets. The drawer's all Strides now and my mornings are simpler for it.

Chris L.

Took these on my honeymoon somewhere tropical. Humidity that fogs your sunglasses. The one thing I packed that I never had to think about. My wife's jealous of how comfortable I am.

Nathan F.

Bought the five pack figuring I'd like one or two. I like all five. They wash great, dry fast, and a month in they feel like day one. Rare to get exactly what you paid for.

Derek W.

I'm retired and just wanted something comfortable for around the house and on walks. Didn't expect to care this much about underwear at my age. Simply the best I've owned. Quality you can feel.

Howard G.

Played 18 holes in 95 degree heat and didn't think about my shorts once. Usually by the back nine I'm a mess. Walked off cool and dry. The guys want to know my secret.

Marsha V.

I work overnight security, walking and standing all night. These keep me comfortable through the whole shift and breathe better than anything I've owned. Picked up two more pairs.
