How to buy a swimming warm suit

Posted on 1st Jun 2019 @ 12:19 AM

A suitable swim thermal wear is essential for learning to swim in winter. However, with so many options available, many people mistakenly think that rash guards are the same as thermal wetsuits. This article explains the differences between wetsuits and rash guards, the characteristics of different materials, and key considerations when purchasing, helping you choose the most suitable swimming gear for yourself or your children.

Difference Between Rash Guards and Thermal Wetsuits

Many people assume that any swimwear worn on the upper body is a thermal wetsuit. In fact, rash guards and wetsuits are two completely different products:

Feature Rash Guard Thermal Wetsuit
Thickness Very thin Thicker (2-5mm)
Material Lightweight breathable fabric Neoprene
Main Function UV protection, quick-dry, breathable Insulation, durability, windproof
Thermal Effect None Yes
Suitable Season Summer Winter / Year-round
Styles Long sleeve, short sleeve, various colours Short sleeve, long sleeve, full body, vest

Important reminder: Although rash guards come in many styles and colours and are widely available, they do NOT provide warmth! For winter swimming, you must wear a dedicated swim thermal wetsuit.

What is Swim Thermal Wear?

Swim thermal wear is specialised insulating equipment made from neoprene. The inner layer features different designs, including towel lining and super-stretch lining, providing insulation and durability. Wearing a thermal wetsuit while swimming in winter effectively maintains body temperature, allowing you to comfortably learn to swim even in cold weather.

Three Types of Wetsuit Materials

1. Neoprene (Basic)

  • Suitable for: Warm water temperatures
  • Features: Effectively provides warmth and comfort
  • Design: Front and back feature windproof coating, keeping you warm even in cold winds
  • Ideal for: General winter swimmers, indoor heated pool students

2. Towel Lining

  • Suitable for: Cold water temperatures
  • Features: Lightweight neoprene with enhanced thermal properties
  • Design: Inner thermal layer features towel-like fibres that stay close to the skin, providing superior warmth
  • Sleeves: Made with super-stretch fabric for unrestricted arm movement
  • Ideal for: Outdoor pool students, people sensitive to cold

3. Super-Stretch Lining

  • Suitable for: Cold water temperatures
  • Features: Entire suit made with ultra-high stretch fabric, providing surprising comfort and flexibility
  • Design: Extremely high elasticity conforms to different body types
  • Ideal for: Comfort-seekers, people with non-standard body shapes

Wetsuit Style Options

Swim thermal wear comes in various styles depending on coverage and warmth requirements:

  • Vest style: Covers torso, arms move freely
  • Short sleeve: Includes half-sleeve, elbow-length, and three-quarter sleeve options
  • Long sleeve: Full arm protection
  • Separates: Top or bottom only
  • Full body suit: Complete coverage, maximum protection

Tips for Choosing Thermal Wear

When purchasing swim thermal wear, keep these key points in mind:

1. Must Try On - Don't Rely on Age or Height Alone

Thermal wetsuits must fit snugly to be effective. Everyone's body proportions differ, so people of the same age or height may need different sizes. Always try before buying to ensure proper fit.

  • Don't buy too large: Loose fit allows cold water to seep in, losing thermal effect
  • Don't buy too small: Tight fit restricts movement and causes discomfort

2. Check the Crotch Area

The most important area to check when determining if a wetsuit fits properly is the crotch:

  • There should be approximately one inch of space at the crotch
  • Besides asking children if it's comfortable, parents must personally check and assess
  • Too tight causes discomfort; too loose affects thermal performance

3. Buy Early to Avoid Stock Shortages

Summer holidays are peak swimming season. Waiting until July to buy often results in:

  • Popular sizes sold out
  • Fewer style choices
  • Potentially higher prices

Recommendation: Buy in May or June for more styles and sizes to choose from.

Wetsuit Care Tips

Proper care extends the lifespan of your swim thermal wear:

  • After each use: Rinse with fresh water to remove chlorine and salt
  • Drying: Air dry in a shaded area, avoid direct sunlight
  • Storage: Lay flat or hang; avoid folding to prevent creases
  • Avoid: Washing machines, tumble dryers, bleach
