Frequently Asked Questions

What is a Lightback swimsuit?

A lightback swimsuit is a one-piece costume featuring thin straps and a mid to low back opening that supports the shoulders and lets them move freely. With this, swimmers can move naturally with each stroke and keep a supportive and secure fit.  

 At Delfina Athletics, we create one-piece suits for athletes, keeping coverage, comfort, and streamlined shape in mind for regular pool use. If you are looking for flexible and reliable women's athletic swimsuits, the lightback style is a dependable choice for both competition and practice.   

Are women’s lightback swimsuits good for training?

Yes, our lightback swimsuits are an amazing choice for training, especially if you are a swimmer who spends several days every week in the pool. The open-back design makes it easier to swim comfortably by supporting full shoulder rotation through high-intensity drills and long sets. 

Delfina Athletics builds this style for athletes who need suits that secure stays in place through dives, flip turns, and longer practice sessions. The durable construction, secure fit, and comfortable strap placement make these suits a practical training staple for every swimmer. 

How do I choose the right size in women’s one-piece swimwear?

Choosing the perfect size depends on how you want the fit to feel at the time of active training. A training one-piece should fit snugly to stay secure in water. However, it should not feel restrictive or overly tight across the torso or shoulders.  

We recommend paying close attention to strap comfort, torso length, and overall coverage when selecting your size. If you are between sizes, we suggest going a bit larger to experience more comfort for active sessions while still preserving a supportive fit. If you are an avid swimmer who values compressive fit, we do not recommend that you size up. Use our size chart to determine the best size for your needs.  

Are these swimsuits chlorine-resistant?

Yes, our lightback swimsuits are able to handle regular exposure to chlorinated pool water. If you train frequently, chlorine resistance is essential because it helps maintain the fabric’s strength, shape, and fit over time. 

We use durable materials built for repeated pool use. Hence, the suit holds up through demanding practice schedules. With proper care, chlorine-resistant construction supports longer wear. 

For athletes who need swimwear that performs consistently season after season, our one-piece lightback suits are ideal. 

Can I customize Lightback swimsuits for my teams or groups? 

Yes, Delfina Athletics offers customization options for teams, clubs, and group programs. If you are seeking a professional and unified presence on the pool deck, we are here for you.   

Our custom one-piece swimsuits allow you to incorporate team colors, logos, or design themes.
