Our top choices

#1 Synergy Triathlon Wetsuit 3/2mm

The quality of materials and excellent neoprene of this wetsuit has provided me with great comfort and performance in the water. Most important, however, is to heed the sizing recommendations from other users. These suits tend to run small, so going at least one size larger is a wise decision. I’ve observed that people with larger athletic upper bodies may find the suit too tight at the armholes. On the bright side, the suit’s design looks and feels solid, even if the fit might be a bit restrictive for some. Many have praised Synergy’s quality and feel, and Amazon’s return policy makes it easy to find the right fit.

#3 Synergy Men’s Triathlon Trisuit

The Synergy Men’s Triathlon Trisuit has become my go-to suit for races and training. It’s exceptionally comfortable, looks great, and holds up well in all three triathlon disciplines. Even with the minor drawbacks, its performance and quality have left me thoroughly satisfied. It might be considered a bit pricey, but in my opinion, it’s well worth the investment. The way the gel pad is sewn and the ease of putting on and taking off the suit are remarkable. It’s perfect not only for competitive triathletes but also for casual participants like me.

#4 Triathlon Wetsuit – Synergy Men’s EpicSpeed Neoprene Sleeveless

In my experience with the Triathlon Wetsuit – Synergy Men’s EpicSpeed Neoprene Sleeveless, I found it to be a solid investment for my triathlon needs. Warm, fully flexible, and well-proportioned, this wetsuit has become a valuable part of my swimming routine. The arm opening and neck allow complete freedom of motion, a huge plus for those grueling triathlon swims. Best of all, NO CHAFFING. I’ve swam significant distances without a single chafe. Besides that, it’s practical, fast, and easy to wear.

However, it’s important to be mindful of sizing. For some, the wetsuit has been too small, leading to discomfort, especially around the neck. A few customers have even reported cold water funneling through the space down half of their back due to the lack of snugness against the neck. But because of the overwhelming positive attributes and some additional measures like applying glide to prevent chafing, these setbacks don’t overshadow the overall functionality of the wetsuit.

Most importantly, the Triathlon Wetsuit – Synergy Men’s EpicSpeed Neoprene Sleeveless is a high-quality product worth the investment. Its buoyancy, flexibility, and ease of wear have made it my preferred choice over full wetsuits. I feel more comfortable, more in control, and can focus on improving my performance. While minor adjustments may be needed to get the perfect fit, the benefits far outweigh any downsides. It’s a product I can rely on, and I may even sell my full wetsuit now.

#5 O’Neill Men’s O’Riginal 2mm Back Zip, Sleeveless, Spring Wetsuit

The O’Neill Men’s O’Riginal 2mm Back Zip, Sleeveless, Spring Wetsuit is a must-have for anyone passionate about water sports. Its comfort and fit are exceptional, particularly for tall individuals like me. I found that the 2x was perfect, even for someone who is 6’3″ and 215lbs. The wetsuit’s build quality is robust, making it a great investment for frequent water sports enthusiasts. Besides that, it’s notably better than the usual neoprene shirts or vests, preventing the rash and discomfort that board shorts often cause.

On the other hand, it’s crucial to note that the product is thin, and you might need to order two sizes over as it runs small. This could result in a snug fit around the shoulders, as I did find it a little tight there. Furthermore, for those venturing into colder waters, the design might not provide enough warmth around the torso, causing discomfort. But this appears to be more of an issue for swimmers rather than surfers, as it’s a fantastic suit for the latter. If you’re into surfing, this could be the right choice for you, especially during long summer sessions.

Most importantly, the O’Neill Men’s O’Riginal wetsuit truly stands out in providing protection and avoiding overheating, even in tropical climates or Hawaiian winter chill. The back zipper design, a considerable improvement over the shoulder Velcro, ensures long-lasting use and comfort. For warm water environments or protection against abrasion during frequent use, this wetsuit seems like the real deal. While it has some areas that could be improved upon, such as size and thickness, its positive attributes more than outweigh the negatives, making it a recommendable product.

Key Features to Consider

When it comes to investing in a sleeveless triathlon wetsuit, several key features should be considered to find the best fit for your needs. These features will affect your comfort, performance, and safety during a race. Here’s a detailed breakdown of what you should be looking for:

  • Material Thickness: Depending on the water temperature you’ll be competing in, the thickness of the wetsuit can be crucial. A 3/2mm wetsuit like Synergy Triathlon Wetsuit 3/2mm is generally suitable for warmer waters, while the 5/3mm variant such as Synergy Triathlon Wetsuit 5/3mm may be preferable for colder conditions.
  • Neoprene Quality: High-quality neoprene like that used in the Synergy Men’s EpicSpeed Sleeveless Wetsuit ensures better buoyancy, flexibility, and insulation. It’s an essential aspect to look for as it directly impacts your swimming performance.
  • Design and Fit: The fit of the wetsuit, such as the tailored design of the O’Neill Men’s O’Riginal 2mm Back Zip, Sleeveless, Spring Wetsuit, should allow you full range of motion without causing chafing. It should be snug but not restrict your breathing or movement.
  • Zipper Placement: Depending on your preferences, you may opt for a wetsuit with a back zip or front zip. A back zip may provide a more streamlined fit, while a front zip could offer more ease in putting on or taking off the suit.
  • Durability and Fabric Quality: If you’re looking for something robust, consider options like SLS3 Triathlon Suits Mens, made with Durable FRT Fabrics. This ensures that the wetsuit can withstand the wear and tear of regular training and competition.
  • Sleeveless vs. Full-Sleeve: Sleeveless wetsuits, such as those listed above, are designed for ease of movement in the shoulder area. They are excellent for swimmers who prioritize flexibility in their stroke and are mostly competing in warmer water.
  • Gender-Specific Design: Wetsuits tailored for men or women, like Synergy Men’s Triathlon Trisuit, offer a more precise fit. This can enhance comfort and performance, as the suit is designed to accommodate the specific body shape and needs of the athlete.
  • Price and Brand Reputation: Investing in reputable brands that are known for quality, such as Synergy and O’Neill, ensures that you’re getting a product that has been tested and proven in real-world conditions. The price should reflect the features and quality of the wetsuit, and it’s always advisable to read reviews and consult with professionals if possible.

In conclusion, when selecting a sleeveless triathlon wetsuit, careful consideration of these key features will help you find the right suit for your specific needs and preferences. Always keep in mind the conditions you’ll be racing in, your swimming style, and your comfort to ensure the best performance on race day.
