Buying Guide for Sleeveless Triathlon Wetsuits
When selecting a sleeveless triathlon wetsuit, consider the following factors to ensure you choose the best wetsuit for your needs:
- Material and Thickness: Hydrodynamic neoprene with appropriate thickness is key. Typically, 3mm to 5mm panels provide buoyancy, while thinner panels at legs and arms improve flexibility.
- Buoyancy and Flexibility: The wetsuit should offer enough buoyancy to assist swimming efficiency but allow full range of motion, especially in shoulders and arms, crucial for triathlon swims.
- Fit and Size Options: Proper sizing is essential to avoid restricted movements or water flushing inside the suit. Look for brands offering a wide range of sizes or custom fittings.
- Neck and Seal Comfort: Smoothskin neck seals that minimize irritation and water entry improve comfort over long distances.
- Zipper Type and Placement: Back zip wetsuits offer easier entry but can increase drag; front zip or sleeveless designs reduce drag and increase swim speed.
- Approval for Competitive Use: If racing in triathlons, confirm the wetsuit is approved by event organizations like Ironman or USAT.
- Multi-Purpose Use: Consider if the wetsuit is versatile for other water sports like surfing or diving, which might offer added value from your purchase.
- Quick Dry and Breathability: Though less common in neoprene wetsuits, some tri suits feature breathable, quick-drying fabrics to improve comfort post-swim or during transition phases.
