Marine Layer Swimwear

Frequently Asked Questions

• What makes Marine Layer swimwear feel so soft and stretchy?

  Marine Layer uses high-stretch blends like nylon/spandex (commonly 86% nylon, 14% spandex) and polyester-stretch fabrics that give a "buttery" hand and excellent recovery. Those blends combined with soft linings—like an absurdly stretchy boxer-brief liner in their shorts—provide all-day comfort and unrestricted movement in and out of the water.
• How do I choose between the Laguna One Piece and the ML x Andie Bikini Top?

  Choose the Laguna One Piece when you want fuller coverage and a sleek, supportive one-piece silhouette for swim-focused days; its nylon/spandex blend offers stretch and shaping. The ML x Andie Bikini Top is a triangle-style, adjustable strap option developed with Andie for technical fit and has a hint of Lurex for subtle shimmer, so it’s ideal if you prefer a lighter, customizable top that’s easy to mix-and-match.
• How do Marine Layer's men's trunks compare—6" Lined Sport & Swim Short vs Mechanical Stretch Swim Trunk?

  The 6" Lined Sport & Swim Short features a lined, stretchy boxer-brief insert, elastic waistband with drawstring, and a zipper stash pocket for secure carry, making it oriented toward active use and quick transitions. The Mechanical Stretch Swim Trunk uses a polyester-stretch shell for fast drying and streamlined mobility; pick the Lined Sport & Swim Short for extra internal support and storage or the Mechanical Stretch for a sleeker, quick-dry trunk.
• What sizing guidance should I follow for Marine Layer swimwear?

  Women’s sizes are offered in XS–XL and product pages include detailed size charts—pick the size matching your measurements for the intended level of coverage (snug for performance, slightly roomier for casual wear). For men, consult each trunk’s sizing guide and consider that nylon/spandex pieces fit closer to the body while polyester-stretch trunks can feel more relaxed; when between sizes, sizing up gives a more comfortable, street-ready fit.
• Are Marine Layer swimsuits suitable for active water sports and for wearing from sand to street?

  Yes, materials like high-stretch nylon/spandex and quick-drying polyester are designed for mobility in the water and rapid drying for post-swim wear. Construction details such as supportive linings, adjustable straps, elastic waist with drawstring, and zip stash pockets make several styles well-suited for surfing, paddleboarding, or casual beach-to-city styling.
