Not every day is a training day

But every day deserves underwear that performs.

The Core Collection is Tweak's everyday essential, the same seamless, no-VPL construction as our performance styles, dialled back for all-day wear. The body is Coolon, so sweat and heat move away from your skin naturally throughout the day not just during workouts. The gusset is bamboo, keeping your most sensitive area naturally soft, antibacterial, and comfortable from morning to midnight.

Same dual-fabric engineering. Same invisibility. Different pace.

Backed by our VPL-Free Guarantee

My wife's new favorite underwear for workouts

I purchased a pair for my wife to try before purchasing multiple pairs.

She says these are her new favorite for working out and runs. The construction is top notch. She says they are very comfortable and better than most g-strings and athletic underwear she has tried. We are both underwear aficionados, and we recognize that the quality exceeds other premier athleisure underwear brands. We will definitely be purchasing more. They truly are seamless and comfortable. No VPL whatsoever.
