Buying Rash Guards For Kids

If your kids love the sun, sea, and sand - then you're in the right place. Here at Trespass, we have a range of kids rash guards designed for your little beach explorers. Kids tend to have far more sensitive skin than adults, so when it comes to playing at the beach it’s important to protect them from the sun and sand. Kid’s rash guards are suitable on their own to save shoulders getting sizzled in the sun or under wetsuits. Shop Trespass Rash Guards online today!

Girls & Boys Rash Vests

Trespass Girls & Boys rash vests are perfect for keeping kids safe – whether you’re at the beach, poolside, or on a swimming lesson. Our kids' rash vests offer protection from UV rays so that you can relax and your little ones can play until their heart is content. Our rash vests are ideal for kids that don't want to wear a full wetsuit - the vest is less restrictive but offers the same protection. Just remember to add SPF to any exposed skin.

Kids rash guards are designed in different styles to suit activity level, coverage needs, and weather conditions.

  • Short sleeve rash guards: Lightweight designs that offer sun protection while keeping kids cool during swimming and casual beach use.
  • Long sleeve rash guards: Provide increased protection from harmful rays and help reduce the risk of sunburn during long hours outdoors.
  • Slim fit rash guards: Close fitting styles designed to reduce drag in the water and minimise chafing during swimming, surfing, or training.
  • Regular fit rash guards: Slightly looser designs that offer comfort for everyday beach wear and relaxed water play.

These options allow kids rash guards to suit everything from casual swimming to active water sports.

Materials and How They Work

The material used in kids rash guards plays a key role in comfort, protection, and durability.

  • Polyester: Durable and quick drying, helping rash guards hold their shape after repeated use in water.
  • Polyamide or nylon: Smooth and lightweight fabrics that feel comfortable against sensitive skin.
  • Elastane blends: Provide stretch so rash guards move naturally with the body during swimming and play.
  • Recycled polyester blends: Offer the same performance benefits with a lower environmental impact.

Together, these materials help rash guards remain flexible, comfortable, and suitable for regular wear.

Small design details make a big difference in how kids rash guards perform.

  • Flatlock seams help reduce irritation and rubbing.
  • High UPF ratings support sun protection during outdoor use.
  • Stretch fabrics allow unrestricted movement.
  • Longer hems help prevent tops riding up in the water.

Together, these features help rash guards feel practical, comfortable, and easy to wear.

Matching the rash guard to how it will be worn helps improve comfort and protection.

  • Swimming and pool use: Lightweight rash guards with quick drying fabric offer comfort in and out of the water.
  • Beach days: Long sleeve rash guards provide extra sun protection during extended outdoor exposure.
  • Surfing and paddleboarding: Slim fit rash guards reduce friction and protect skin from boards and equipment.
  • Snorkeling and water play: Smooth fabrics help avoid irritation while protecting against sun and saltwater.

Choosing the right style ensures kids stay comfortable and protected across different activities.

Are rash guards suitable for both swimming and surfing?

Yes, rash guards are designed to be worn during swimming, surfing, and other water activities. Their stretch fabrics and smooth finishes help support movement while reducing friction from boards and gear.

Do rash guards provide UV protection?

Most kids rash guards include UPF rated fabrics that help protect skin from harmful rays. They work alongside sunscreen to reduce sun exposure during long hours outdoors.

What’s the difference between a rash guard and a wetsuit?

Rash guards are lightweight tops focused on sun protection and reducing irritation, while wetsuits are thicker neoprene garments designed to provide insulation and warmth in colder water.
