Make it a one-and-done day with an athletic one piece swimsuit.

Equal parts performance and style, one piece swimsuits are the perfect option for when we’re setting out for parts unknown. Comfortable, with just the right amount of coverage, women can move, groove and make waves in a one-piece suit that’s up for the challenge.

What activities are best to wear a one piece swimsuit for?

The short answer? Most anything women can do in a bikini or tankini, women can do in a one piece swimsuit. But one-piece bathing suits are especially good sporting swimwear for days that demand a low maintenance choice, high sun coverage, or support and coverage in all the right places:
- Going for a swim? For lap swimming, look for a high neck sporty swimsuit with built-in support that’s no frills (forget the lace-up, bandeau or ruched options here) and all performance. Bonus points for a chlorine-resistant fabric.
- Hitting the surf? Long sleeve full-coverage one-pieces can be the just-right choice for women who surf—especially when a wetsuit is too much, and a rash guard is too little. Look for swimwear made of high-performance quick drying swimsuit fabric with UPF 50 protection, or, if you need a little extra warmth, look for neoprene options. Unlike a bikini and rashguard combo, choosing a one-piece means you never have to worry about losing your bikini top in a wipe out.
- Beach bumming it? Swimsuits one piece or bikini, can both work for hanging around the beach. Look for on-trend bathing suits silhouettes like ruched, cheeky, cross-back, cut-out, and twist-front options. Don't forget to check for support (no matter your boob size) for those pick-up beach volleyball games or beach path bike rides.

Is a one piece swimming suit good for competition?

Yep, many of our athletic swimsuits are great swimwear for sports like triathlons and competitive swimming. When shopping for sporty swimwear for women, there are a couple of key features to look for:
- Fit: One piece swimwear should be form-fitting, but not so tight that they restrict movement or interfere with proper form. The right size swimsuit should also prevent chafing (one that's too big can rub and irritate while on a swim)
- Material: A quick-drying, chlorine-resistant, technical fabric (with UPF protection if you’re competing outside) will keep you comfortable and chafe-free. Check out swimsuits made with SurFlex™, our resilient, colorfast, stretch-resistant UPF 50 swim fabric.
- Style: Look for swimwear styles with crossback, racerback, or narrow set shoulder straps (so your suit straps won’t slip off while you swim) and bottoms that provide ample butt coverage (to avoid mid-race wedgies).

What are the benefits of long sleeved swimsuits?

Long sleeve swimsuits have tons of perks:
- They have built-in sun protection (especially if they’re made out of a fabric that’s UPF 50+).
- They’re an easy one-and-done choice (forget digging through drawers to find your matching sun shirt cover-up).
- When you're headed out for water activities, these long sleeved one-piece swimsuits are just a bit warmer in chilly water. (Every little bit counts!)

Is a one piece bathing suit more supportive?

Gone are the days of thin, show-everything bathing suits—many of T9’s one-piece swimsuits have built-in shelf bras and removable soft cups for coverage and support in flattering fits, from strappy, crisscross one-pieces to ruched, floral, skirted one-pieces. Adjustable straps, halters, and back ties can also help customize your fit and level of support, while high-neck and underwire options can help keep the girls (no matter their size) under wraps.
