Looking for the best cold water swimming wetsuit for women and need a little pointer in the right direction, then I’m here to help you.

Not all wetsuits for women are created equal – most are designed specifically with either surfers or open water swimmers in mind. If you exclusively swim, make sure you choose a suit designed just for swimmers, like the six tried-and-tested wetsuits in our round-up below.

While you can always wear a surf wetsuit for a quick dip, a swimming-specific wetsuit will really give you the edge if you’re getting fit over longer distances or are entering your first swim event. Swimming wetsuits are usually made from thick materials like neoprene and yulex rubber, which trap in heat and warm water around your body, keeping you at a comfortable temperature for longer. They usually have slimmer neoprene around the arms and legs, to reduce drag in the water and keep you feeling flexible as you move. You’ll also find short swimmer’s wetsuits that can be armless or sleeveless, designed to give you some protection in spring and summer.

What we look for in the best women’s wetsuits

Thickness: Besides having long or short arms and legs for more or less coverage to suit different seasons, wetsuits are also designed using different thicknesses of neoprene, which you’ll see rated in millimetres. Swimming wetsuits have thinner neoprene around the arms and armpits than surf suits for ease of movement, and are cut in order to reduce drag in the water. If you’re only buying one suit for casual swimming a 2mm is probably your most versatile pick. If you swim year-round, owning a full-length thermal winter wetsuit with 3 or 4mm of neoprene on the torso and a short-sleeved ‘shortie’ wetsuit of 1.5 or 2mm thickness will keep you comfortable in every season.

Material: Traditionally, wetsuits have always been made of neoprene. Neoprene is great as a warm wetsuit material for swimmers heading out in cold conditions, so it’s still a sensible choice, but this petroleum-based fabric is not kind on the planet. Now there’s a new material on the block that wetsuit makers are now using to create wetsuits – yulex rubber. This renewable, plant-based rubber is more sustainable than neoprene, but it’s still flexible, durable and has heat-holding properties, so it’s ideal for winter waters. Yulex suits are often more expensive than neoprene, but are worth the extra spend if you’d like to make an eco-friendly purchase. Look after your new wetsuit by rinsing in fresh water after wearing, especially if you’ve been swimming in salt water, and dry in a shady place.

Fit & Design: Swimming wetsuits are designed to be quick and easy to pull on and off, to suit the needs of triathletes, who need to change on the fly. Try your suit on in person if you can – sizes can vary greatly between brands. Some suits allow you to trim the legs and arms to fit, which is a good choice if you’re petite. We recommend a suit with long arms and legs for winter swim sessions – if you like some protection in warmer months, pick a sleeveless, full-leg suit for swimming, which allows the arms free movement but keeps your legs and torso cosy. Winter wetsuits are sometimes also lined with thermal fleece, which adds welcome extra warmth. While most wetsuits are black (neoprene’s base colour, which offers good UV resistance), some women’s wetsuits also feature bright pops of colour which have the added benefit of making you easier to spot in the water.
