Sleeved versus sleeveless wetsuits for triathlon: which is best?
Wondering what are the advantages of a sleeved versus sleeveless wetsuit are? We explain all...
It’s time to choose your next triathlon wetsuit, or maybe you’re buying one for the first time. But you can’t decide on a sleeveless or full-sleeved wetsuit. In this article, we cover the pros and cons of both styles and what you should be looking for in your next suit.
Choosing the right wetsuit for your triathlon race and training is crucial for performance and comfort. Whether you opt for a sleeveless or full-sleeved option is a key decision. The main factor that comes into play here is the climate.
Swimming in colder water will likely necessitate a full-sleeved wetsuit, which also adds overall buoyancy and thus in some cases, speed through the water. On the other hand, a sleeveless suit brings many advantages, especially when it comes to fit and whipping it off quickly in transition during a triathlon race.
As a side note, be sure to consider the wetsuit regulations for your triathlon race, as some races will not accept competitors to use sleeveless suits under a certain temperature. The main factors to consider when choosing your type of wetsuit are : water temperature, swimming experience and preference, and swim distance.
Each option has distinct advantages and uses, and understanding these can help triathletes make the best for them.
The benefits of sleeved triathlon wetsuits
Superior insulation
Long-sleeved wetsuits provide greater coverage than their sleeveless counterparts, which translates to better insulation in colder water. These suits are typically thicker and the full sleeves reduce the amount of skin exposed to cold temperatures, helping to maintain body warmth during extended swims. This feature is particularly beneficial in races held in chilly open-water conditions or during early morning starts when water temperatures are low.
Improved buoyancy and hydrodynamics
Good quality long-sleeved wetsuits are designed with advanced neoprene materials such as Yamamoto that enhance buoyancy. The aim of this is to raise the body in the water so that it forms a hydrodynamic line, equalling a more efficient swim stroke. As long as you have a good, snug fit to the wetsuit, the full-body coverage will reduce drag in the water.
Protection from the elements
Though most triathletes opt for full-sleeves for the warmth element, the coverage has the added benefit of protecting against sunburn, jellyfish stings, and abrasions from rocks or debris. For triathletes competing in open water with potential hazards, this extra protection can come in very handy.
The benefits of sleeveless triathlon wetsuits
Greater freedom of movement
Sleeveless triathlon wetsuits allow for a more natural range of motion in the shoulders (rotator cuffs specifically) and arms. This is because the absence of material around the shoulders eliminates any restriction, making it easier to perform a full, fluid stroke. Those who tend to have shoulder issues when swimming may find a sleeveless suit a better choice.
Comfort in warmer temperatures
In warmer water conditions, sleeveless wetsuits are often more comfortable. The reduced coverage prevents overheating and allows for better heat dissipation, helping athletes maintain a more comfortable body temperature. There’s also less chance of wetsuit chafing around prime spots like the underarms.
Easier to put on and take off
Sleeveless wetsuits are typically quicker and easier to don and remove, which can save valuable seconds during transition. Especially in short-distance triathlon racing, the time savings of a sleeveless suit outweigh the potential downsides. The simplicity of a sleeveless suit could be particularly appealing to beginner triathletes, who may find full-sleeve wetsuits cumbersome.
