  • Let’s start at the top and work our way down the suit.
  • One of the great features of the Endorphin is the thin and super smooth neck.

 neck.jpg     neck2.jpg

  • It is designed to fit low on your neck, which eliminates chafing. It goes under your adam's apple.
  • It has 1mm thin smooth skin on both sides, which creates a seal and because it is so soft, it feels like you hardly have anything around your neck
  • You can see here just how smooth and super flexible it is.


  • And when held up next to this orca suit…   there is simply no comparison…


  • Going down to the shoulders and arms you will notice that it is just one super flexible 2mm thick panel. By eliminating extra seams, you maximize a panels flexibility.


  • The lower arm panel is ribbed, which helps you grab the water better.


  • You will notice that some other brands have various grip panels, but let me tell you that those do NOT work, because they create as much resistance during the glide phase of the stroke as they gain during the catch phase.
  • The grip panel on the Endorphin is ripped in forward, which means that there is NO resistance during the glide phase, but as soon as you begin the pull phase of the stroke, the panel catches water as it moves around the arm, which helps propel you forward faster.
  • You will notice that some brands use a similar ripped panel, but turn the rips sideways, which is completely ineffective, since it creates resistance during the glide phase and NONE during the catch phase. It underscores how even some of the most established brands are clueless on how to do this properly.


  • Moving down, the Endorphin features a large 5mm thick Buoyancy panel, that we call The AquaLift panel, which stretches from the upper chest all the way to the knees. This panel will keep you floating high in the water and is the maximum thickness allowed for maximum buoyancy.



  • All Synergy suits are Ironman approved, ITU approved, USAT approved and FINA open water approved.
  • On the back, the suit features a large aqua Velcro patch, which allows for superior adjustability, so you can make the neck closure fit just the way you like it.


  • The zipper is the highest grade anti corrode wetsuit zipper from YKK.
  • It is an internal zipper, which means that it greatly reduces drag as you move through the water.


  • The zip lanyard has Velcro on the tip, which allows you to attach it to the neck patch. The cover flap is designed to protect the zipper during the swim from your competitors AND it is made so that you can tuck the lanyard inside.
  • When you exit the water, you simply pull the cover flap and reach for the lanyard.
  • The two back side panels are the BioAlign panels, which are stiffer panels that helps the swimmer align their spine while swimming, which helps eliminate ‘Snaking’, which is one of the issues facing many triathletes and which create a lot of drag.


  • Below the knees, the panel thickness goes to 3mm, which allows for an effective kick. It has also been shown to be the right thickness to insure proper balance in the water and insure that your hips do not dip in, which often happens in suits with 5mm thick lower legs.
  • We use an ultra smooth lining in this panel that make it super fast to exit during T1.
  • The speedcut heel is cut at an angle to insure easy entry and easy exit. This suit is incredibly fast during transition!


  • You can see how to put the suit on and how quickly you can get it off on our website:
  • This covers the basics on this suit, but there are more features and you can read about them in the product description below.

Thank you for considering Synergy!

  1. The best service, the best suit.

    Posted by Fernando on 23rd Apr 2014

    They advised on the size and the suit fits like a glove (I was a difficult one). Their Chat and telephone customer service is great.The suit is awesome, Sinergy really delivers at great great price. They sent an upgrade. It helped a lot to correct my sinking legs problem. I searched in a lot of webpages and wetsuit outlets and I can assure there is no better option than to get a great suit at a great price.

  2. awsome all round!

    Posted by Unknown on 20th Apr 2014

    First time tri suit. 61kg and 179 cm and got s2, really good fit, easy to get off, and delivery to Australia was unbelievable! 4 days! Cheers and will shop here again soon! :)

  3. Just buy it

    Posted by walker on 16th Apr 2014

    Great tri suit but it's the most beautifully engineered bodysurfing wetsuit ever.

  4. great wetsuit!!!

    Posted by Stephen Romano on 15th Apr 2014

    This is a great quality wetsuit. The price is amazing. The service was impeccable. Shipping was fast. Will definitely recommend to anyone! You cannot go
    Wrong with the endorphin and with wetsuit!!

  5. Really slick.

    Posted by Andy C on 9th Apr 2014

    This wetsuit is so fast, it left without me. 'Left me floatin' there in my Speedos. (not a pretty sight).

  6. I have never written review before, but this product deserves it.

    Posted by Ryan Adamson, Reno, NV on 20th Mar 2014

    I have never written a review before, but after buying and training in the Synergy Endorphin suit, I am a believer! I was pretty skeptical when I bought it, but thought what the hell, I can always send it back - even after 60 days, which is unheard of. Well, I PR'ed in my first swim. I have owned lots of of wetsuits over the years, but this one is by far the best.

  7. Just buy it!

    Posted by Stephen Jenner, Portland, OR on 14th Mar 2014

    You can't go wrong with this suit and this price. I own an xterra and a tyr suit, and I can tell you they are junk compared to the synergy endorphin. I have been doing triathlons for the past 10 years and I can't believe I haven't tried synergy before now. Very high quality, VERY flexible (much more than any other suit I have ever tried), and the fit is perfect for me. I am 165 lbs, 5'10 and the M1 fits me perfectly!
    Service from wetsuit was perfect as well. Very impressed all around.

  8. best value

    Posted by jake k on 12th Mar 2014

    It's been a long while since I purchased a good Tri specific wetsuit. I race enough to warrant a new one, but not so much that I needed to spend hundreds. Given the fantastic reputation, reviews, and bang for the buck of the Synergy brand, I started to see I could not go wrong with a Synergy Endorphin. But I was dead in the middle of two sizes, and calling customer service and working through the details with some of WO's staff was a huge help! That alone will keep me from purchasing anywhere else. My suit came fast, packaged well, and fits perfect so far. Knowing I got it from a reputable place that really paid attention to my needs, and had a top-notch warranty on top of it all, made it an fantastic experience. Sharing Wetsuit Outlet with everyone I race with. Keep up the great work and thanks again Wetsuit Outlet.

  9. Brilliant!

    Posted by Stephen McCarthy, ID on 5th Mar 2014

    This is one awesome suit! I can't believe the quality and value. Very rare these days! The suit arrived 3 days after I ordered and it fit like a glove. Very flexible and floats like a dream. Used it at our local pool the first time and although it got hot after a while, it was a pleasure swimming in it.
    I highly recommend this suit to anyone looking for a great buy with lots of neat features!

  10. Good value and excellent service

    Posted by Nick on 20th Feb 2014

    This is the first swimming/tri wetsuit I've purchased and had some questions about sizing and fit. I called and spoke with Brandon. He was very knowledgeable and suggested a size. I placed the order and it was delivered as I expected (with goggles and cap thrown in too!). After trying it on, I'd say it was a perfect fit. Great customer service response and good value of a suit. I'll be buying from them again.
