The Ultimate Swim Shirt Buying Guide: Dive In Comfortably

Swim shirts, also called rash guards, are awesome gear for anyone spending time in the sun and water. They protect your skin and help you stay comfortable. This guide will help you pick the best one for your next adventure.

Key Features to Look For

When shopping, check these important features first:

Sun Protection Rating (UPF)
  • Look for a high UPF (Ultraviolet Protection Factor) rating. UPF 50+ is the best. This means only a tiny bit of UV light gets through.
  • Higher UPF means better sun safety for long days outside.
Fit and Coverage
  • Choose a fit that feels snug but not too tight. A close fit stops the shirt from ballooning up in the water.
  • Consider sleeve length. Long sleeves offer the most sun protection for arms.
Seam Quality
  • Examine the stitching. Good shirts use flatlock seams. Flatlock seams lie flat against your skin.
  • Poorly stitched seams cause rubbing and irritation, especially when wet.

Important Materials Matter

The fabric decides how the shirt feels and dries. Most swim shirts use synthetic blends.

Nylon and Spandex/Lycra Blends
  • Nylon is strong and dries fast. Spandex (or Lycra) gives the shirt its necessary stretch.
  • This blend offers great flexibility for swimming, surfing, or playing beach volleyball.
Polyester Blends
  • Polyester is durable and resists fading from chlorine and saltwater well.
  • It often feels slightly softer than nylon but might take a tiny bit longer to dry completely.
Chlorine and Salt Resistance
  • High-quality materials resist breaking down from pool chemicals or saltwater. Cheap materials wear out fast.

Factors That Improve or Reduce Quality

Quality isn’t just about the fabric. How the shirt is made really counts.

Improving Quality
  • Thicker fabric generally offers better durability and sun protection.
  • Look for shirts with built-in features like thumbholes. Thumbholes keep the sleeves down when you are active.
  • Some shirts include antimicrobial treatments. These treatments help stop funky smells after heavy use.
Reducing Quality
  • Thin, cheap fabric stretches out easily after washing. This makes the fit baggy.
  • Poor colorfastness means the shirt fades quickly when exposed to strong sunlight.

User Experience and Use Cases

Think about what you will actually do while wearing your swim shirt.

For Active Water Sports
  • If you surf or paddleboard, you need a shirt that resists rash. Look for smooth, flat seams.
  • A slightly tighter fit helps prevent drag in the water.
For Casual Beach Days
  • If you just plan to relax by the pool, comfort is key. Softer fabrics are a good choice.
  • Look for lighter colors, as they absorb less heat from the sun.
Drying Time
  • Everyone wants a fast-drying shirt. Quick-drying fabric means you aren’t sitting around in a cold, wet layer after you get out of the water.

10 Frequently Asked Questions (FAQ) About Swim Shirts

Q: Are swim shirts necessary if I wear sunscreen?

A: Yes. Sunscreen washes off. A UPF 50+ swim shirt provides constant, reliable protection, even when you are swimming hard.

Q: How should a swim shirt fit?

A: A swim shirt should fit snugly, almost like a second skin. It should not be baggy, especially when wet, or it will slow you down.

Q: Can I wear a regular long-sleeved shirt to swim in?

A: You can, but a regular shirt offers very little UPF protection. Also, cotton shirts soak up water, get heavy, and take forever to dry.

Q: Do swim shirts protect against jellyfish stings?

A: They offer a physical barrier, which helps reduce minor stings. However, they are not specifically designed for heavy sting protection.

Q: How should I wash my swim shirt?

A: Always hand wash your swim shirt in cool water with a mild detergent. Never use bleach. Air drying is best to protect the spandex.

Q: Will chlorine ruin the fabric?

A: Chlorine damages elastic fibers over time. Choose polyester blends if you swim often in heavily chlorinated pools. Always rinse the shirt immediately after swimming.

Q: What is the difference between a rash guard and a swim shirt?

A: These terms are often used interchangeably today. Historically, rash guards were thicker for board sports, but modern swim shirts offer the same protection with lighter fabric.

Q: Do swim shirts run hot in the sun?

A: Good quality swim shirts are designed to be breathable. They wick moisture away, which actually helps keep you cooler by promoting evaporation.

Q: Should I choose light or dark colors?

A: Darker colors actually absorb more UV rays before they reach your skin, offering slightly better protection than white fabric of the same UPF rating.

Q: How long do swim shirts usually last?

A: With proper care, a high-quality swim shirt can last several seasons. If the fabric starts pilling or losing its stretch, it is time for a new one.
