★ 4.8 Most LovedWhy the 362
362 Cooling Thigh Protectors 6"
Stops friction. Kills the heat. Disappears under any outfit.
-
Flat-Fiber Cooling Architecture
The 80% nylon flat-fiber weave physically moves sweat away from skin — it doesn’t absorb and hold it. Body heat escapes faster than it builds.
-
Zero Compression
No panels. No shaping bones. No sausage-casing sensation. These are engineered to eliminate friction and dissipate heat — not to squeeze.
-
Stays Put All Day
The 80/20 nylon-spandex construction recovers its shape after every stretch. Wear them under a dress for a full day without adjusting once.
-
Invisible Under Any Outfit
Ultra-thin lightweight fabric and flat-seam construction are specifically designed to be invisible under fitted clothing — even through thin summer dresses.

Built for real bodies. Six sizes, four colors. Order two sizes if you’re between fits — Underoutfit pays return shipping both ways.
Real Women, Real Results
★★★★★
Wore them for 9 hours straight. Forgot I had them on.
“I’ve tried every anti-chafe solution out there — powders, bands, compression shorts. The 362 is the first one that actually feels like nothing. Cool, smooth, and stayed in place all day at a summer wedding. I ordered three more pairs the next morning.”
★★★★★
Finally — not a shapewear in disguise
“Every other option I’ve tried either rolls up or squeezes me like a sausage. These do neither. They’re light, they breathe, and they’re invisible under my dresses. This is what thigh protectors are supposed to feel like.”
★★★★★
The cooling is real
“I was skeptical about the ‘cooling’ claim but it’s genuinely different. Wore these on a 90-degree day and my thighs were actually comfortable. The fabric feels silky and doesn’t bunch or shift. I’m a convert.”

What Makes It Different
362 Cooling Thigh Protectors 6"
Stops friction. Kills the heat. Disappears under any outfit.
01
Cools Down As You Heat Up
The 80% nylon construction is built around a silky-smooth weave that physically moves sweat away from skin — it doesn’t just absorb it and hold it. Wear them on your morning commute, a summer wedding, or a nine-hour travel day. They work the same at hour one as at hour nine.

The Opposite of Spanx — By Design
No compression panels. No shaping bones. No sausage-casing sensation. These are thigh protectors engineered to disappear under any outfit — light enough that you forget you’re wearing them, smooth enough that nothing shows through. The 20% spandex is for stretch and recovery, not squeezing.
Zero-Compression Construction

Flat-Fiber Architecture: The Engineering Behind Why These Actually Cool
Most fabrics trap a layer of warm air against your skin. The 362 uses a yarn with a flat cross-section — a wider surface area means body heat escapes faster than it builds. The texturizing process opens up the weave so air circulates through the fabric, not just around it. This isn’t a marketing claim. It’s the structural reason the fabric works — and why regular nylon shorts don’t do the same thing.
Engineered BreathabilityThe 362 Difference
Two Problems. One Solution.
Most anti-chafe shorts solve the friction. The 362 solves both.
Friction-Free
Silky-smooth flat-fiber surface eliminates inner-thigh chafe from the first step to the last.
Actively Cooling
Flat-fiber architecture releases body heat as fast as you generate it. No trapped warmth. No sweat buildup.
