What Exactly Is A Rash Guard?
In short, a rash guard is a thin piece of clothing used to protect your skin from rash and irritation whilst also providing warmth and protection from the sun.
They can be worn underneath a wetsuit for extra insulation and rash protection, or in warmer climates they can be worn by themselves for rash and sun protection. They’re usually made from materials such as spandex, nylon, polyester or neoprene and are designed to insulate and breathe at the same time.
Rashies are used across all sorts of water sports and are particular popular among surfers and kayakers as they protect your skin from rashes and irritation that can be experienced from repetitive movement (paddling) or brushing your skin up against rough surfaces (surfboards).
You’ll find that a lot of the rash guards out there will offer sun protection, with a UPF rating. This means the Ultraviolet Protection Factor and shows how much sun protection the clothing can provide.
The higher the rating, the more protection the clothing can give you. Unlike the ratings given to sunscreen lotions (SPF), the UPF rating can show how much of the sun’s rays can be blocked by the fabric rather than how long you might be able to stay in the sun before you burn.
UPF rated clothing can protect your skin from both UVA and UVB rays.
Rash guards are often designed for warm weather use when it would be too warm to wear a wetsuit, so they will tend to be lightweight. A rash guard is generally not designed to keep you warm.
The fabric used will often be lightweight, moisture wicking fabric that is designed to wick moisture away from your body, which can also help to draw perspiration away.
These moisture wicking fabrics are also designed for breathability and because of their moisture wicking properties, they should dry pretty quickly too - meaning if you do sweat, your rash guard shouldn’t theoretically stay wet.
You may come across several materials that can be used in rash guards, each offering different levels of breathability and weights, with polyester being one of the most breathable.
If you’ve been to the beach or pool recently, you might have noticed people wearing rash guards for swimming and they can often be ideal for swimming.
However, you might find that some of the looser fitting options may not be the best choice, as the tighter performance fit options can provide less resistance in the water.
Plus, with the tighter fitting rash guards, there might be less chance of you getting caught on other objects, particularly if you’re surfing too.
A rash guard could provide you with more sun protection than traditional swimwear, which can be a good reason to wear one. This can often be why you might see lots of younger kids wearing them at the beach.
Types of Rashies
Rash guards come in various styles for various uses. Some are made primarily for rash protection and are designed to protect your more sensitive areas such as armpits, nipples and necks.
Others are made more with insulation and sun protection in mind.
Rashies also come in shorts or full suit form, allowing protection to your legs and pelvic areas or your entire body in the same shape as a full wetsuit.
You can also get thermal rash guards which are designed specifically to provide extra insulation and are therefore a better choice for chilly climates. Usually made from neoprene, the thickness of a thermal rash guard will be displayed with two numbers separated by a slash on the label.
These numbers refer to the thickness of the material in millimeters, the first number is the thickness around the torso and the second number refers to the material around the limbs (which is usually thinner to allow smoother movement).
How Do I Size One?
For active water sports, your rash guard should be fitted nice and tight. Although not necessarily flattering for all body types, this will minimize chaffing and rubbing when moving around (they are called rash guards for a reason after all).
You can also get loose-fitting rash guards but these should be used for less active sports where movement is minimal or restricted. Most brands and stores will offer online sizing charts to help guide you towards the best fit for you.
