Burpees. Box jumps. Mountain climbers. Sprints between sets. HIIT doesn't just make you sweat — it moves your body in every direction at once, fast. If your underwear was built for sitting at a desk, this is where it gives up first: riding up, bunching, shifting — or camel toe, right in the middle of your set.
Why HIIT is the hardest test for underwear.
Steady-state cardio is one direction, over and over. HIIT is the opposite — explosive, multidirectional, and unpredictable. One minute you're jumping, the next you're lunging sideways, then you're on the floor for mountain climbers. Underwear that's just soft and stretchy tends to ride up, bunch, or shift with every direction change … which means you're adjusting between exercises instead of resetting for the next one.

What to actually look for.
- A patented anti-camel-toe design — a real structured front panel, not just soft fabric — that holds its shape through jumping, lunging, and floor work, not just standing still.
- Moisture-wicking fabric that can keep up with a sudden, heavy sweat — HIIT dumps more sweat in 20 minutes than a lot of workouts do in an hour.
- A rise and cut that stays put through squats and floor work without digging in or rolling down.
Why cotton falls apart mid-circuit.
Cotton is absorbent, not moisture-wicking — it soaks up sweat and just holds onto it instead of moving it away from your skin. That's fine for a slow day. It's not fine for a workout where you're sweating in bursts every 30 seconds. HUX uses a bamboo charcoal insert that pulls moisture away and lets it evaporate, so it's not sitting damp against you between rounds, paired with a nylon-spandex body built to hold its shape through explosive movement, not just look good standing still.
Want the style that shows the least? The thong is your lowest-profile option. Want more coverage with the same stay-put structure? The hipster's got you.
Bottom line: if you're resetting your underwear between exercises, it's not built for HIIT. Look for real structure and fabric that handles a sudden sweat, not just a soft feel in the store.
