Gear Review: blueseventy Helix Wetsuit

Wetsuits are one of the larger gear investments a budding triathlete can make; behind a bike and/or race wheels (if, of course, you fall into USAT's median income range of approximately $108,000), it is likely a wetsuit will be your most expensive piece of gear.

With that kind of money on the line, then, it stands to be prudent when it comes to selection. Much like when it comes to proper triathlon bikes and running shoes, fit comes first. Then you can start worrying about the features of a particular suit versus another. This means that if you are part of the crowd screaming, "I can only wear a sleeveless," it is more likely that you either have an abnormally shaped torso (there are indeed certain people who just can't fit into a sleeved suit), or you have never had a sleeved suit that fit you properly.

But, what if you enjoy the feel of the water against your arms, or simply prefer a thinner feel to the sleeves of the suit? Most wetsuit companies really build up the forearms of their suits to create catch panels, with the theory that they will help move more water.

Enter the blueseventy Helix.

The Tech Babble
Wetsuits, at their core, have been using the same kind of material for decades: neoprene. Regardless of brand or fit, you'll be buying a suit made of this material, much like how in running shoes, you'll for the most part be buying an ethylene vinyl acetate product.

Neoprene, due to its smoothness, helps reduce drag in the water. However, because there are air molecules trapped in the rubber (much like how air molecules trapped in the midsole of a running shoe provide the cushioning), the air helps to provide lift, and therefore buoyancy.

Of course, having a whole bunch of rubber surrounding your skin in the water also helps keep you warm. Too warm, in some instances. This is why there are temperature cut-offs for wetsuits: because you run the risk of severe overheating if the water temperature is high to begin with. The suit will only make it warmer! For Rev3 events, the water temperature cut-off for awards is 78 degrees; nobody is permitted to wear a wetsuit when the water is warmer than 84 degrees. For those planning on racing say, Rev3 Maine or Rev3 Cedar Point with me: I think we have nothing to worry about. We'll be wearing wetsuits.

There is also a limit to the thickness of the wetsuit: 5 millimeters at its maximum. This is, again, to limit overheating due to the suit being too thick, and also too much buoyancy help from a wetsuit. As it is, wearing a suit with 5 millimeter thickness is impossibly buoyant; you basically need only scull with your pinkies in order to stay afloat.

That is not to say, though, that all suits with 5 millimeter thickness in them are made the same. Nor should all of the suit necessarily be made to this thickness; sure, we want the buoyancy, but we also need to be able to move in the suit! If you can't move your arms well enough to take an effective swim stroke, then you haven't made any sort of improvement by putting on a wetsuit.

Furthermore, although buoyancy can help out any swimmer, there are different types of buoyancy needed for different people. If you are like most triathletes who come from a cycling or running background, the mass will be in your legs, and you have a difficult time raising the hips to avoid the dreaded "swimming uphill" position: pushing water down with your torso, legs behind you sinking towards the bottom. However, if you have more of a swimming background, your body positioning tends to be better; you want the suit to give you some of the sleekness and buoyancy, but to some degree get out of the way.

blueseventy, named for the fact that water (blue) covers seventy percent of the Earth's surface, recognized this as well. There are two product ranges that blueseventy manufactures: the neutral buoyancy line, and the positive buoyancy line. The neutral buoyancy products are thicker in the torso and core, whereas the positive buoyancy suits focus more on buoyancy through the core, hips, and legs, much like swimming with a permanent pull buoy.

The Helix slats in as the top-of-the-line neutral buoyancy suit. It tiers the maximum thickness of the suit as 5-5-4, with the first section through the torso, the middle section as the core and hips, and the final section throughout the legs. So, the legs are a touch thinner than the top two sections. This isn't to say that they will sink when in the water; instead, blueseventy's research suggests that because the legs are constantly in motion (read: work on your kick, buster, because you're supposed to be kicking in a triathlon swim...), this thickness provides the best balance of buoyancy and freedom of motion.

The core and hips are also constructed slightly differently from the torso. The suit features what are called Aerodome panels in the midsection. Remember above how we talked about the rubber having air molecules trapped in the matrix? Well, increase the volume of those air molecules, and you have Aerodome: same thickness, more buoyancy. This is to help promote that downhill swimming position.

But what of the arms and shoulders, the part of the suit that makes people cringe? This is where blueseventy takes a completely different course as compared to other suit manufacturers. Most suits will feature a butterfly panel, opening up the shoulders and arms, before building to large "catch panels" in the forearm, designed to help move more water during the swim stroke. The problem? These catch panels also create drag in the water, particularly if you have a longer glide before initiating the pull. Also, if you don't get the suit just right in the shoulder, it will feel as if it is pulling down on the arm.

blueseventy's solution? Let's go all minimal up top! The suit has some of the butterfly in the shoulder and back, with 2 millimeter thickness there. But then there are 1.5 and 1 millimeter panels all throughout the arms. And they're not even neoprene; it's fabric! The result: supreme freedom of motion. But it also can help out from a form standpoint; it will allow you to take that swim stroke you've been honing in the pool and bring it directly into the open-water; no form modifications necessary. This can help reduce injury-risk, but also increase awareness of what is working and what's not working; it's easy to make modifications in technique when the suit is so flexible.

The Helix was designed with triathlete's in mind, as there are some answers to common problems that we tend to face. Take, for instance, the run into the water for beach starts, or the run from the water to transition. The Helix has a thinner panel behind the knee to allow you to be able to run easily with the suit on. Also, the zipper works in reverse: when putting the suit on, it zips from the neck down. To remove, pull the cord up. This makes sure that if somebody gets a hold on that pull cord during the course of the swim, it's not pulling the zipper down off your suit and letting a whole bunch of water in.

The Swim: How's It Work
This suit is FAST. As in, holy crap.

As we reviewed before, I swam in the Orca Sonar last season, and another Orca suit for part of the year this year. You would think that, being 6'3" and 158 lb., I would fit well into a suit that is pretty narrow.

And you'd be wrong: the Orca line is designed with folks who fit onto the Felt's and Cervelo's of the bicycle world in mind: long torso, shorter to average length legs. I am, of course, built the opposite way: super long legs, next to no torso. To give you an idea, when doing the Rev3 Maine bike course preview with Jen Small, her response to attempting to draft off of me while on board Wallace the Blue: "You're all legs! No draft comes off of you!"

So, in other words: the Orca line was a poor match. It resulted in some shoulder impingement, simply because I could never get the suit's torso to really match up. Orca also was a little narrower in the shoulders and chest overall. In sum: I should've gone with something different.

This is the suit.

First off, the rubber in this suit simply works. To test it out for yourself, just go for a standard beach start, run in, dive in (please, in a familiar area where you know where you won't hit your head...), and just take off.

You are GONE.

Seriously, this thing just up to speed wants to stay up at speed. And you feel that speed, too. If this is the first time you've worn a wetsuit, the phrase "this is cheating" will probably come to mind. And that's OK. It's not cheating. But it is speedy!

As you start moving into your swim stroke, you'll notice how easy it is to keep your hips high in the water. One thing that I noticed was that this suit really likes to have your head "buried," so to speak: relax your neck to allow your chin to point towards your chest. It really gets you into that downhill swimming position. The two panels on the sides of the front chest will also prevent you from jacknifing at the midsection while you turn to breather, giving you a much more effective position and forcing you into proper torso rotation.

Your legs will float behind you, but again due to some of the torso panels you will have less of the fishtail action that is incredibly common in poorer swimmers (often due to core strength issues). It's really attempting to streamline you and move you towards the direction that you want to be moving in.

And then the arms: what a difference! You really get a good idea as to where you are in the swim stroke, and also knowledge of how small changes in turnover rate and forearm placement will impact your speed in the water. It's incredible how flexible and easy it is to move in this suit. For those who have shorter torsos and have had issues with sleeved suits in the past, stop looking. Go try on a Helix.

For the rest of us, this suit will really make some improvements for you. It is a blazing fast suit that, considering the attention to small details, really pays off in the end. I couldn't be happier to have found this suit out. It makes me a better swimmer.

And when you're paying for a wetsuit, isn't that what we're looking for?

A Swimming Revelation

Full disclosure time: I'm not a swimmer.

Well, let's explain this one a little bit. I was never a competitive swimmer. I didn't race. I never competed against other teams. I wasn't a YMCA kid. High school? The most athletic thing I did then was letter in marching band. (It was a varsity sport. Won New England championships. Stop rolling on the floor laughing.)

But, on the other hand, I learned how to swim at the Y when I was 4. My parents had an above ground pool when I was growing up. I'd be in that thing every day from Memorial Day until Labor Day, churning out a few laps across (all 24 feet of it). We'd also wind up racing each other, trying to go back and forth. It's how I learned to flip-turn, just so I could keep my advantage on my brother (who has infinitely more natural athletic talent than I, the bastard).

So to summarize: I wouldn't call myself an expert on competitive swimming. But I've got two decades worth of experience in the water. And about four months of experience in actual, honest-to-God lap training.

As I've started to come into my own stroke, and seeing lap times drop (down from 9:16 500s all the way to 7:28), there have been four major keys to my swimming that I'd thought I'd share. Your results can, and probably will vary, but we'd at least be able to have the discussion about it.

The Water is Your Friend: One of the many things that has been difficult to recognize is the relationship that you need to have with the water. Yes, we float, but we also sink a little bit (especially when you're *cough*153 lb. *cough*). We don't have gills, either, so there's an inherent fear of the water built in.

The thing is, you need to work WITH the water in order to be able to move through it well. Thrashing about is not going to make you a better swimmer. You need to appreciate that it's resistance is also the propulsive force. This is why they call the hand entry the catch, and the actual "stroke" the pull: you're grabbing the water, and pulling it behind you. In that effect, it's more like the old rope climb in gym class than you might initially recognize.

You also need to be unafraid to put the head underwater and stare at the pool bottom. As you move through your stroke, you will have a little bubble to the side to breathe out of. So go ahead, and stare down at the lane marker. It'll be OK. You will breathe air.

Slow = Smooth = Fast: I had previously put this at the end of a blog posting talking about my own swimming technique. This is one of those completely counter-intuitive items, but if you think about it, along with the previous key, it makes a lot more sense.

The smoother you are in the water, the more you can focus on how much water you catch, and then pull through. In order to be smooth, you need to potentially slow your stroke rate down a touch. The more water you move per stroke, the faster you go. So as my stroke rate has decreased, I've seen dramatic improvement in my swimming time.

Two quick drills: get into the pool, and count how many strokes it takes for you to get down and back. Then try to take 10 less strokes, and then try to take 10 more strokes than that base number. Record your times, and see what works for you.

Also, one-arm drills will improve your stroke turn-over so that you are always either catching, or pulling. This limits the amount of space between strokes, allowing for you to continually be gliding through the water (remember, we're not fighting the water, we're working with it).

Streamlining: This is by far the toughest, at least for me. My kick is ALL over the place, making it completely inefficient. We want to keep you in a single, smooth plane to limit the amount of resistance created by the water. Again, gliding through it.

So, with that head down in the water, we want your hand to not cross over and create too much angle. We want your kick to flow directly behind you, rather than your body moving all over the place. Think of being like a torpedo in the water: straight. True. Focused on the end of the pool. This will hurt the back and abs like hell the first couple of times...but it hurts so good.

Nothing Replaces Hard Work: What, you thought you were going to get faster just with that? PLEASE. Get in the water. Now.

You're still here?

2000 yards. Right now.

Have fun!
