  • 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. Perfect!!! 5 Star Review

    Posted by on 13th Apr 2015

    First of all, I am 6'3'' 188 pounds and the M3 size is absolutely perfect for me.

    Very fast shipping to Canada.

    I will buy again here for sure!

  2. Beyond a great deal 5 Star Review

    Posted by on 27th Mar 2015

    I was amazed what a good quality suit this is. I had an Xterra before that cost more than my new Synergy and it fell apart after less than 10 swims. The Synergy Endorphin is quality from top to bottom and fits amazingly well.

  3. Great Wetsuit 5 Star Review

    Posted by on 13th Nov 2014

    I just completed my first triathlon (in 30 yrs), and my Synergy wetsuit was great!! I am 5'8" 170 and purchased size M1. My weight put me between sizes and after talking to Wetsuit Outlet(I wish I knew the name of who I talked with), I decided to go with the smaller choice. He told me, that it would be too small until I had worn it, up to 10 times. When I first tried to put it on, it was so small, that I could barely squeeze it on, and zipping it impossible. But by the time I swam my first race, and 10 times of putting it on, it was snug, but a perfect fit. During my swim I never once, was aware of the wetsuit. No restriction in the shoulders, and nice and warm. The boyancy takes a few swims to get used to, but I swim at least 10 seconds per 100 faster. This is a great wetsuit, and I highly recommend it!

  4. Great wetsuit for the price 5 Star Review

    Posted by on 12th Nov 2014

    I wanted to have a good number of swims under my belt before I left a review. I have used the wetsuit a few times a week for 2 months and it is a great wetsuit. The last time I used it was for the swim in an ironman last month. The suit doesn't restrict your shoulders more than normal and keeps you buoyant. No need to spend a lot of money when you can get a suit like this. Totally worth it.

  5. Not bad.... 4 Star Review

    Posted by on 9th Oct 2014

    meets all the was perfect...but the zip arte adown the base of the suit bunches up a bit...may have been cut incorrectly but otherwise ok

  6. great fit, easy to get in and out of 5 Star Review

    Posted by on 7th Oct 2014

    Just completed my first tri where a wetsuit was needed. And this new purchase was put to the test! Weather was fierce -- 42 degrees, 20-30MPH winds. This wetsuit saved the day. I was nervous about getting out of it during T1, but it was a breeze! Highly recommend!

  7. First time wetsuit wearer 4 Star Review

    Posted by on 14th Sep 2014

    The wetsuit did what I needed it to do. I should have gone up to M2, but that is my own fault for waiting so long prior to my triathlon to place an order.

  8. Exactly what I wanted 5 Star Review

    Posted by on 11th Sep 2014

    After going through the first year, this suit provided exactly what I wanted. Purchase with confidence.

  9. Great suit...great price!! 4 Star Review

    Posted by on 14th Aug 2014

    I just received my Endorphin Full Sleeve and the fit is perfect (5'-7'' 165lbs - Size M1). I look forward to try it in the lake next weekend.
