The Synergy Endorphin Fullsleeve Triathlon Wetsuit is a high performance full sleeve wetsuit providing you with flexibility, flotation and speed at an exceptional value. Designed and constructed for optimum balance between buoyancy and flexibility, it is perfect for all levels of ability, be it competing in triathlons or for open water recreational swimming.
At Synergy Wetsuits, we sell more wetsuits than any other triathlon company on the planet. This means that we also have lots of size exchanges, warranty suits and rental suits. Once a suit has been worn and returned to us, we cannot sell this suit as new. These suits are sold on our outlet section as demos.
We rate our DEMO suits as follows:
A = Almost new / Lightly worn
B = Used / Repaired. May have some cosmetic flaws.
Since these wetsuits are being sold at demo/clearance prices, returns and exchanges can only be refunded as store credit as long as they are returned within 30 days.

A new wetsuit should feel performance-snug on land. Once you start swimming, it will settle onto your body and feel more natural after a few uses.
The suit should feel tight on land because it will relax and settle once you are in the water.
Putting on a wetsuit while wet or sweaty makes fitting much harder and usually leads to a poor setup.
Brand-new suits loosen up and become more flexible after several uses, so allow a short break-in period.
The suit is not a dry suit, so some water will enter. If you experience excessive sloshing, the suit may be too big and could require a size exchange.
If the suit feels tight while swimming, try opening the neck slightly to allow a little water in.
New suits become more flexible after a few swims, so give the fit a little time before making a final call.
