Modifying Your Triathlon Wetsuit: What You Need to Know

Inside the arms and legs of your wetsuit, you’ll find approximately 7 cm of seam tape. This reinforcement allows you to trim the length if necessary. However, any cuts beyond this seam tape will require additional reinforcement to prevent fraying and maintain durability. In a pinch you can do this on race-day, just make sure you reinforce later.

Many athletes prefer customizing their wetsuits for ease of use. For example, some opt for a mid-calf cut (a “capri-style” modification) to facilitate quicker transitions during races. In fact, many triathletes who don’t “need” the extra 4-6 inches below the knee cut their wetsuit legs to make it easier to put their wetsuit on and also take off during transition.

In fact, one of Xterra Wetsuits’ highest-end wetsuits, the Vengeance, already is designed as capri-cut: https://www.xterrawetsuits.com/collections/mens-fullsuits/products/vengeance-fullsuit-triathlon-wetsuit . So, basically any other model can be made capri-cut / mid-calf.

If you decide to trim beyond the built-in seam tape, we recommend reinforcing the cut edges with seam tape—such as McNett or Gear Aid Black Tenacious Tape, available on Amazon.

Steps for Cutting Your Wetsuit:

• Measure twice, cut once using a sharp pair of scissors.
• It does not matter whether you cut the wetsuit inside-out or right-side out.
• No additional sealing is required for the outer neoprene layer.
• If cutting beyond the existing seam tape, apply additional seam tape on the inside to reinforce the edge. Follow the instructions of the supplier of the seam tape, and make sure your wetsuit is very dry.

Again, any modifications to your wetsuit render it ineligible for return or warranty claims. Ensure the fit is right before making adjustments, as the wetsuit cannot be exchanged or refunded once altered.
