Not every day is a training day

But every day deserves underwear that performs.

The Core Collection is Tweak’s everyday essential, the same no-VPL construction as our performance styles, dialled back for all-day wear. It’s made from a breathable, quick-drying fabric, so it stays comfortable from morning to midnight, not just during workouts.

Same no-VPL design. Different pace.

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.

I absolutely love my tweak purchase! They are super comfy and dont ride up in all the wrong places even at gym and especially when doing squats. The colours are beautiful. The fabric feels amazing and breathable, will definitely be buying another pack in the other colours.

The products are not only delicious in colour combination. The fabric is to die for, breathable, flexible and sexy AF! I have four colours and can't wait for more! Its hard to find great gym underwear, that feels like you aren't wearing any, but this also has become my anytime underwear!
