 Summer 2025 is just around the corner, and families everywhere are planning beach trips, pool parties, and sunny getaways. If you’re a parent, that means one thing - It’s time to upgrade your kids’ swimwear. But with so many options on the market, how do you find swimwear that checks all the boxes: style, sun safety, comfort, durability, and affordability?

The best kids' swimwear this season goes far beyond just looking cute. From eco-conscious materials to UPF protection, the 2025 trends are all about combining practicality with fashion. In this blog post, we’ll explore the top kids' swimwear picks for summer 2025, what features parents should prioritize, and how brands like August Society are setting a new standard for sustainability and style.

Why the Right Swimwear Matters for Kids

Whether your child is splashing in the ocean, running through sprinklers, or taking swim lessons, quality swimwear makes a big difference. Choosing the right swimsuit:

  • Enhances comfort and mobility

  • Offers crucial UV protection

  • Reduces the risk of chafing or irritation

  • Saves money by lasting longer

  • Encourages confidence and fun

With that in mind, let’s break down the key factors to consider for this summer’s swimwear picks.

1. Summer 2025 Swimwear Trends for Kids

This season, swimwear for kids is embracing bright colors, playful prints, and smart features. Here are the leading trends:

 Sustainable Fabrics

More parents are prioritizing eco-friendly choices. Brands like August Society use recycled fabrics such as ECONYL® (made from ocean waste) and rPET (recycled water bottles), blending environmental responsibility with premium quality.

 Bold, Playful Prints

From marine animals and jungle themes to tie-dye and tropical motifs, 2025 is all about personality-packed swimwear that kids love to wear.

 Matching Rash Guards and Sets

Sun-safe swimwear is now more stylish than ever. Rash guards, long-sleeve tops, and matching bottoms or shorts are popular not only for sun protection but for cohesive, Instagram-worthy outfits.

 Reversible Designs

Want more value in one piece? Look for reversible swimsuits that offer two styles in one - perfect for kids who like variety and parents who like saving money.

2. Key Features to Look for in Kids' Swimwear

When shopping for summer swimwear, here are the top five features parents should prioritize:

UPF 50+ Sun Protection

Choose swimwear labeled UPF 50+, which blocks 98% of harmful UV rays. This is especially critical for children’s delicate skin.

 Stretch and Fit

Look for swimwear with 4-way stretch fabric to allow full freedom of movement. Adjustable straps or waistbands also extend the usable life of the garment.

 Flatlock Seams & Soft Linings

Prevent chafing and irritation by choosing swimwear with flatlock stitching, smooth linings, and tagless designs.

 Fast-Drying and Chlorine-Resistant Materials

Durable swimwear won’t lose shape or fade after a few pool days. Quick-dry fabrics are also ideal for all-day wear.

 Ethically Made and Non-Toxic

Many reputable brands ensure their products are made in safe, ethical factories and free from harmful dyes or finishes.

4. Budget-Friendly Tips: Save Without Sacrificing Quality

Buying high-quality swimwear doesn’t always have to mean breaking the bank. Here’s how to maximize value while keeping your kids comfortable and protected:

 Shop Off-Season

Retailers often mark down last season’s inventory in early spring or late summer.

 Opt for Gender-Neutral Designs

These can be passed down between siblings more easily, increasing lifespan and savings.

 Choose Adjustable Fits

Look for pieces with adjustable straps, drawstrings, or elastic waistbands that grow with your child.

 Invest in Multipurpose Sets

Some rash guard sets can double as playwear or even athletic wear outside the water.

5. Safety First: What Parents Need to Know

Swimwear is just one part of keeping your child safe this summer. Here are a few essential reminders:

 Apply Broad-Spectrum Sunscreen

Even with UPF 50+ swimwear, exposed areas like the face, ears, and feet still need sunscreen.

 Reapply Every Two Hours

Especially after swimming or sweating. Consider reef-safe formulas that are better for the ocean and your child’s skin.

 Use Accessories

Pair swimsuits with sun hats, water shoes, and sunglasses for full protection.

 Always Supervise

Even strong swimmers need active adult supervision in and around water. No swimwear replaces safety awareness.


6. The Sustainable Choice: Why It Matters

Choosing sustainable swimwear helps:

  • Reduce ocean pollution

  • Support ethical manufacturing

  • Lower your family’s carbon footprint

  • Model mindful habits for your kids

Brands like August Society prove that being environmentally responsible doesn’t mean compromising on style or quality. Plus, with longer-lasting swimwear, you save money and reduce waste over time.

Final Thoughts

Summer 2025 promises sunshine, fun, and memories your family will treasure. Make the most of it by investing in high-quality kids' swimwear that delivers on style, safety, and sustainability.

Whether you’re planning beach vacations or backyard pool days, the right swimwear keeps your kids comfortable, protected, and happy. From playful patterns to eco-friendly innovations, this season’s options offer something for every family.
