🐪 Zero camel toe

💦 Sweat + leak resistant

💋 Snatched seamless fit

✨ No digging in - no muffin top

Meet the Outie Athletic G-String!🐱💦 The 4-in-1 gym g-string every active girl’s been replacing their underwear drawer with.

Because honestly? Every single gym-girl problem...the camel toe, the sweat patches, the chaffing, panty lines, the digging waistband, the discharge, the MUFFIN TOP! I’ve brought them all into one solution because your body was never the problem.

Made for movement: A design that combines comfort and functionality making it a staple for the active queen or anyone who's simply sick of picking underwear from out of their crotch that wasn't made for them. 

4-in-1 Functions

  1. No camel toe or labia lines - Keep your vulva tucked in with our built-in shield for a clean and confident look
  2. Leak resistant lining - Holds everyday discharge, sweat and light spotting - no back up pads or liners needed.
  3. Seamless & Sculpting Fit - No VPL (visible panty lines) just a smooth finish under any outfit
  4. No Chaffing, No Digging - Our wider, higher gusset is intentionally shaped to actually cover and support your vulva. No more tugging or discomfort

Designed with you in mind

Confidence in the gym: No more camel toe on the hack squat, no coochie sweat on the bench, no awkward mid-set adjustments. The built-in shield’s got your bits covered.

Performance fabrics that deliver: Thin, breathable, antibacterial, and moisture-wicking with a soft bamboo cotton gusset that keeps your vulva healthy, happy, and fresh.

Real Talk? - “I’ve spent years in the gym feeling uncomfortable, self-conscious, and frustrated by underwear that clearly wasn’t made for women who move. I took every problem I’ve ever had in the gym and built one solution. It took months of testing, tears, late nights, and trial runs, but seeing you girls love it already makes it all worth it. From the bottom of my heart, I hope you love the Outie Athletic G-String as much as I do.”
