All that you need.

If you're thinking about buying the Blueseventy Helix Women's Wetsuit, you're probably wondering if you can place in the top ten at next year's Ironman, not what it might be like to train for your first triathlon. In case the price hasn't made it clear enough, we'll say that the Helix is the top-of-the-line wetsuit for serious triathletes who are looking for every advantage. It's assumed that expert triathletes have already mastered their swimming technique, so the Helix doesn't waste too much time on enhancing proprioception (the exceptions are the ultra-thin Honeycomb Aqua Feel forearm panels, which are designed to increase awareness of arm positioning, in turn boosting power, enhancing technique, and reducing injury risk). Instead, the Helix focuses on buoyancy and flexibility, the characteristics most important to top-quality athletes.

To that end, Blueseventy employed thinner Yamamoto neoprene on the arms and lower legs, in addition to thin and seamless Torsional Stretch Technology panels on the deltoids. This provides unparalleled mobility in the water, along with the shoulder freedom that's essential for powerful strokes. Medium-thickness Body Fit Panels allow for unrestricted core rotation for increased power and buoyancy, while the split VO2 chest panel is anatomically matched to the lungs, providing maximum stretch during respiration while maximizing buoyancy.

Ah, the "B" word. Buoyancy is perhaps the most important wetsuit feature for top-of-the-line athletes, as it reduces the percentage of your body that's actually moving through the water, in turn minimizing drag and maximizing efficiency. The Helix is built on a 5-5-4 pattern, concentrating buoyancy around the hips, lower torso, and upper hamstrings, which helps you achieve an efficient and powerful "downhill" swimming position, so you can focus on propelling yourself forward and not on raising yourself up and out of the water. This will save you time and keep you fresher, so you can fully appreciate the easy removal encouraged by the thin Quick Exit legs, flared ankle, and comfortable reverse zipper when you're powering out of the water and getting ready to jump on your bike and crush the next stage.

  • 5-5-4 buoyancy pattern (chest-torso- arms/lower legs)
  • Torso and VO2 Chest panels with 5-millimeter Yamamoto neoprene
  • Torsional Stretch Technology along deltoids (distinctive blue panels)
  • Ultrathin arm panels: 1-millimeter Yamamoto 40 cell neoprene
  • Quick Exit Legs: 2-millimeter lower leg panels
  • Aquaseal cuffs with 4-way stretch
  • Reverse Zipper entry/exit

Love the Mobility in the Shoulder's!

  • Size Bought: Small

Absolutely love my Helix! I know you should never do this but I never got a chance to test it out before my triathlon race, so the first time I ever wore it was on the starting line at Wildflower 70.3. I had one of by BEST swims, felt GREAT! I love how my shoulders didn't get sore, I feel the difference from my old wet suit (not blueseventy) and it was a night n day difference! LOVE THE HELIX!!

Love the Mobility in the Shoulder's!

Best wetsuit ever!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I have not been able to find a full sleeve wetsuit that I was comfortable swimming in as my shoulders would fatigue so quickly. I was then turned on to the helix and I absolutely love it!! It is so flexible in the shoulder area that I can swim without my usual shoulder fatigue! Looks great and performs fantastic!

Love the Helix!

This is the most comfortable wetsuit I have tried since starting to do triathlons. I used to get anxious swimming in a wetsuit bc I felt strangled, but not with the helix! Also, the shoulder flexibility / range of movement it provides is second to none ... and don't forget about feeling buoyant, it is superb in that way as well.

Better than the best

I thought I had been rocking a high-end wetsuit, but after it incurred some premature stretching and tearing, I switched to the Blueseventy Helix. The improvements were off-the-hook! The comfort, fit, lightweight design, and lack of chafe points were immediately evident. More important than comfort, though, is performance, right? I simply feel more confident; as appo see to competing high-end wetsuits, the Helix has three-times as many strategically placed materials of various buoyancy. From the innovative paper-thin forearms to the buoyant neoprene at the core, I sense I have an edge where I need it the most. I'll never wear anything but Blueseventy.

Best in Class!!

  • Familiarity: I've used it several times
  • Fit: True to size

The Helix is THE gold standard for wetsuits. It's a huge confidence boost to know when I'm on that starting line that I have the fastest wetsuit available. What has really surprised me about the Helix is how light it feels when I'm wearing it. A lot of wetsuits feel bulky and/or feel like they inhibit the movement of my arms and shoulder, but the Helix feels like an extension of me. Plus, an excellent fit/construction around the neck means no race hickeys! I HIGHLY recommend this wetsuit!

Blueseventy Helix Rocks!

    I can't flip turn in the lake but love a rope swing approach. I have competed in many triathlons and multiple Ironmans. I still have my first wetsuit and my second wetsuit .. Yes, and a third (but it's for surfing) And then I bought a Blue Seventy Helix and stopped buying wetsuits!!!! I love the mobility of this suit. I love how you can feel the water when you pull.. A lot of thought went into these sleeves. I love the craftsmanship and attention to detail in the entire suit. Sometimes I will still do an open water practice swim in one of my crappy suits .. Because when I put on my Helix .. It's like zipping up in your race wheels. Can't go wrong, find your size and get yourself one!!

    Blueseventy Helix Rocks!

    Love my Blueseventy Helix

    I can't flip turn in the lake but I like to approach my my open water swims from the rope swing!

    Love my Blueseventy Helix

    Best Wetsuit out there!!!

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I've been wearing the Helix for the past three triathlon seasons. It is comfortable, non-restrictive in the shoulders, and FAST!!! I love the sleeves! They are thin and flexible making it possible to move smoothly, but still thick enough to provide for warmth, even in our early season, Northeast chilly swims! I highly recommend this suit to everyone!

    Best wetsuit money can buy!!

    • Size Bought: WM

    This wetsuit is well worth the $! I have worn it a lot this year and it is still like new. There is buoyancy where needed. The sleeves are my favorite: they are thinner and more pliable than other suits but thick enough to swim in Alcatraz. I recommend this suit to everyone I know.

    Great wetsuit

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    Coming from a swimming background means a certain amount of discomfort with full-sleeve wetsuits --until I tried the Helix. The arms are thin, the shoulders are incredibly flexible, and the rest of the suit is well-balanced and doesn't throw off my natural stroke at all. It's a great-fitting wetsuit, perfect for so many water temperature and conditions. Buy with confidence.

    Top end performance

    • Familiarity: I've used it several times
    • Fit: True to size

    If you're concerned about being comfortable, the Helix is the best on the market. All seams are well tapered to avoid discomfort and chaffing. Zero chest constriction (that people often complain about with wetsuits) and no problem feeling any strain in my shoulders. Also, the suit helped me to keep my body position and correct form in the water. Overall, I give this wetsuit two thumbs up. The quality and craftsmanship can't be beat.

    Top end performance

    Best. Wetsuit. Ever.

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I have tried many brands of wetsuits and am always uncomfortable and feel so slow. I actually am always hoping for a non wetsuit swim. Until now! The helix fits perfectly, keeps me warm and afloat. I've had my best swims this year in this suit. Everyone should have one!

    Best. Wetsuit. Ever.

    I don't how Blueseventy does it but every year their wetsuits keeps getting better and better. This Helix wetsuit was perfect and my favorite. Very comfortable around the neck. Loved the flexibility around the shoulders. Knees for running out of the water bend. Easy to take off. Reverse zipper. Perfect.

    The Helix is unparalleled in quality and performance. I've been a faithful Blueseventy user for 3 triathlon seasons now and can't say enough great things about this product! The suit is durable and fits beautifully for adequate range of motion where swimmers need it most.

    Unanswered Question

    What is the difference between this Helix and the other one you have on sale? The specs looks the same. Is this one the 2015-16 version? I'm particularly interested in ensuring that the sleeves style/technology are the same. Thanks
