1. Thinx Leakproof Bikini Bottom

Why We Love It:

This sleek, classic bikini bottom offers built-in absorbency that holds up to 1 to 2 tampons’ worth of fluid, making it perfect for light flow days or spotting. It’s also water-resistant on the outside, helping prevent leaks in and out of the water.

Best For:

  • Light flow beach days
  • Wearing as a backup with a tampon or cup
  • Teens looking for low-profile protection

2. Thinx Hi-Waist Bikini Bottom

Why We Love It:

The hi-waist silhouette is not only on-trend but also offers a more secure, full-coverage fit, making it ideal for those who want extra confidence. Like the bikini bottom, it includes multi-layer technology that absorbs and locks in fluid.

Best For:

  • Those who prefer more tummy coverage
  • Lounging or low-activity days
  • Swimmers seeking style + security

3. Thinx One-Piece Swimsuit

Why We Love It:

This one-piece blends a sporty, streamlined design with the brand’s signature leakproof gusset for light period protection. It’s flattering and supportive, with thick straps and a modest cut that’s perfect for movement in the water.

Best For:

  • Moderate beach activity
  • One-and-done swimwear lovers
  • People who want maximum coverage and comfort

4. Thinx Adjustable Bikini Bottom

Why We Love It:

With its adjustable side ties, this bikini bottom allows you to customize your fit—great for growing teens or anyone between sizes. Despite its minimal design, it still offers Thinx’s light-flow absorbent core.

Best For:

  • Fashion-forward beachgoers
  • Teens and tweens
  • Pairing with your own swim tops

5. Thinx Sport Swim Bottom

Why We Love It:

Designed for more active swimmers, this bottom features a secure athletic cut and quick-dry fabric. It’s great for light workouts, beach volleyball, or quick dips. Plus, it pairs well with rash guards or sporty tops.

Best For:

  • Active beach days
  • Watersports or training
  • Those wanting sporty style with function

How to Choose the Right Style for You

Choosing your ideal Thinx Swimwear depends on a few key factors:

  • Activity Level: Opt for a one-piece or sport bottom if you plan to swim or move a lot.
  • Style Preference: From high-waisted to adjustable bikinis, choose the silhouette that makes you feel most confident.
  • Coverage Needs: One-pieces and high-waist bottoms offer more coverage and support for extra peace of mind.
