Description

Designed for versatility and comfort, the Active-Flex Wetsuit supports a wide range of water activities while being engineered for both front crawl and breaststroke swimming. Replacing our best-selling Aspect Wetsuit, it features a breaststroke-friendly construction with thinner neoprene in the legs and a large gusset/crotch panel, allowing natural leg movement and ensuring legs remain submerged. 

A 3mm Yulex® Natural Rubber chest panel provides core insulation, while the high-stretch 3mm and 2mm neoprene blend delivers unmatched flexibility. The hydrodynamic Speedflo-coated shoulder, upper arm, and collar panels reduce drag for smoother, more efficient swimming, while waterproof glued and blindstitched seams enhance durability and warmth. Abrasion-resistant knee panels improve longevity for board sports. 

Designed with ease of use in mind, the Active-Flex Wetsuit is easier to put on and take off compared to fully smoothskin-coated wetsuits. Strategic orange paneling enhances visibility in open water, ensuring you stay seen while staying active.

How To Measure

An ill-fitting wetsuit can cause discomfort and reduce the effectiveness of the suit. This guide will provide some tips and tricks on how to get the perfect fit for your wetsuit, so you can enjoy your time in the water to the fullest.

Getting the right size wetsuit is important as a suit that is too loose will let too much water into it and a suit that is too tight will make for an uncomfortable swim.  We normally say if the suit feels tight on dry land, but you can move your arms comfortably then it’s a good overall fit.

Where body measurements can put you into a number of different sizes we use the weight as the deciding factor and although the height is significant, it is secondary to the weight.

When putting on your wetsuit, undo the zip and crease the suit in half so you can step into the legs of the suit. Pull the suit on using the inside, fabric-side, of the suit to avoid damaging the outside smooth neoprene with your fingernails.  Try instead to use the pads of your fingers. Also avoid rushing to put on as this will get you hot and the suit will be harder to get in to.

The seam on leg of the suit should run of the inside of the leg. The longer end of the leg holes should be aligned to the front and the shorter sides to the back. Be sure you move the neoprene in the legs up towards your crotch. Pull the neoprene in the arms of the suit towards your shoulders. Make sure not to use your fingernails at any point.

Hold the base of the zipper with one hand while using the pull cord to do the zipper up. Be sure the inner zipper panel sits flat underneath the zipper. If possible have someone help you do the zipper up. It is important to push your shoulder blades together so it is easier to pull the zip up.

The suit should fit snugly but not uncomfortably. If the collar feels too tight, be sure the suit is high enough in the hips and have someone help pull the back of the suit up through the zipper towards your shoulders.

When removing the suit undo the zipper before undoing the collar. Make sure you are holding the shoulder or body of the suit when you remove it.

You can follow these simple guidelines to ensure that your wetsuit stays in the optimum condition:

  • Rinse well in fresh water after every use. 
  • Minimise time left in direct sunlight and aim to dry in the shade. 
  • Dry inside out first and then dry outside. 
  • Best kept flat and folded behind the knees and then in half, best stored in a cool place. 
  • Only use a hanger for short periods of time and use as wide a hanger as possible. 
  • Do not allow others to use your wetsuit. It has been fitted for your body shape and no body larger. 
  • Avoid contacting the velcro with the inside lining of the wetsuit as this pull on the sensitive fibres. Keep the velcro covered with the fabric patch. 
  • Ensure you do not damage the wetsuit material with fingernails. 
  • Avoid use in chlorinated swimming pools. 
  • Always use a plastic bag to help put the legs and arms on. The smooth surface of the plastic makes the suit go on easier. This results in less adjustments needed and less contact with the material to achieve the correct position. 
  • The Zone3 triathlon wetsuit range has been designed to optimise performance during racing. Its use should be restricted to swimming or triathlon racing. 
  • Don't put it in the washing machine or tumble dryer. 
  • Don't iron. 
  • Don't wash with detergent or bleach.
