01Overview

The Triangl Adjustable Bikini Bottom is a sleek, minimalist piece built for swimmers who want both comfort and a flattering silhouette at the beach or poolside. Crafted from Triangl's signature neoprene-blend fabric, the bottom offers a smooth, second-skin texture that moves with the body while maintaining its shape through repeated wear and water exposure. The low-rise cut sits comfortably on the hips, creating a sporty yet feminine look that pairs seamlessly with the brand's matching triangle-style tops, making it easy to mix and match across different Triangl collections.

What sets this bikini bottom apart is its adjustable side straps, which allow wearers to customize the fit according to their preferred coverage and comfort level. Whether tightened for a more secure, cheeky fit or loosened slightly for a relaxed feel, the straps give the piece a versatility that's often missing from standard fixed-cut swimwear. The hardware used for adjustments is designed to withstand saltwater, chlorine, and sun exposure, ensuring the bottom remains functional and durable through multiple seasons of beach trips, pool days, and vacations.

Available in a range of solid, vibrant colors that reflect Triangl's bold aesthetic, the Adjustable Bikini Bottom appeals to those who want a swimwear staple that feels modern and body-conscious without sacrificing practicality. The quick-drying material resists sagging and stretching out of shape, even after hours spent swimming or lounging in the sun. Its compact, barely-there design embodies the brand's reputation for sexy, minimalist swimwear, while the adjustable feature ensures that wearers of different body types can achieve a personalized, secure fit that feels as good as it looks.
