  • 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. I love my new wet suit

    Posted by Steve Collar on 21st Jul 2014

    My wetsuit is comfortable, easy to get on and off. It cleans up well and dries fast. It is a very cool wetsuit for the price and it gives me incredible buoyancy in the water when I swim in the ocean. I swam in Santa Monica at tower 26 on Sunday morning at 9 a.m. with a group of other swimmers. I did about a mile and I felt great. I am a newbie to swimming in the ocean, but the wetsuit gave me super powers. I would not have done as well with out this wetsuit. I have a lot to work on as a new ocean swimmer, but I am one step closer to completing my first triathlon and I will be doing it in my new Synergy wetsuit.

    Thanks for all your help.

  2. My first tri suit, easy-peasy

    Posted by Johnnie K on 14th Jul 2014

    I was glad I talked to a sales rep, because otherwise I would have ordered the wrong size. Works like it was supposed to and felt very natural even on my first swim (but then I windsurf with surfing wetsuits so I have some familiarity). Definitely makes a difference swimming-- feels like I am paddling a raft!

    Whoda thought a wetsuit company in Minden NV...

  3. comfy entry level suit at great price.

    Posted by David on 3rd Jul 2014

    Second suit I have ever owned. Seems very well built and has good flexibility and quite buoyant. Best thing is the price, can't beat it anywhere. Also shipping was faster from the US than what we can get things sent within Australia.

  4. Tremendous suit

    Posted by Ricky on 3rd Jul 2014

    I am a novice to Triathlons and bought this suit for my first one. I've swam in it a couple of times and the fit is great, very streamline in the water and lightweight. Comfortable and all and all a great suit for me.

  5. Impressive!

    Posted by Unknown on 3rd Jul 2014

    Suit is comfortable and very flexible. Buoyancy was impressive. Suit is easy to get on and off. Wearing the suit I cut almost four minutes off my 1500M time.

  7. A torpedo of a wetsuit

    Posted by Charlie Davidson on 12th Jun 2014

    Wow, what an amazing wetsuit, swimming in the open water has never felt so wonderful, the buoyancy and balance of the wetsuit is so perfect you soon forget you have it on.
    The suit flexibility makes it extremely easy to put on a take off and the quality of its construction and detailing is fabulous.
    I will be swimming everyday from now on.

  8. Fast, Soft, adds confidence

    Posted by Unknown on 30th May 2014

    Really loved how much faster this seemed to make me swim. The exterior is so slick. Love the flotation and body position balance in the water it provides. Excellent quality. Heading out right now for another training session. Thanks.

  9. Great Product with great service

    Posted by crystal perry on 26th May 2014

    Wetsuit outlet has been a great company to work with. They helped find me the right wet suit and helped me with sizing. It fits great!!!! I really like my new synergy suit.

  10. Amazing value!

    Posted by Ian McTaggart, Seattle, WA. on 21st May 2014

    I have researched this purchase quite extensively. My last suit was a piece of cr*p (Xterra) and I had a hell of a time getting warranty when the zipper broke. So I wanted my next suit to be hassle free. I am not one for taking the time to write a review, but I feel this product really deserves it (obvioulsy a lot of other people before me did too, but that is not going to hold me back after what I have experienced). When I got the suit, I was happy to see that it looked well made, that it was flexible right away (the sales person at wetsuit outlet told me that most suits need to be used a little before their full flexibility met their potential). After my first swim, I was impressed with how well it fit, how easy my arms moved and just how great it was in general. I had not expected that for only $200, but I had read what others wrote online, so I thought it was worth trying out. The sales person told me there was no risk and that I could get my money back plus the shipping if I wasnt 110%satisfied. Anyway, what really impressed me was that I snagged the suit on my bike about a month after I got the suit. I was bummed because it was my own fault, but I remembered that wetsuit outlet offered free repairs as part of the deal, so I called them and to my complete delight they said "no worries, just send the suit back and we will send you a brand new replacement..."!!!!!!!!! Are you kidding me??? Who does that now a days???? I was blown away! This company and the suit deserves a gold medal for customer service and for quality at an amazing value.
