Triathlon Stainless Steel Water Bottle - Insulated BPA-Free, Leak-Proof in 12oz/18oz/32oz for Endurance Sports

Choose the 12oz for short sprints where you want lightweight hydration, the 18oz for Olympic distances to balance weight and capacity, or the 32oz for longer half or full Ironman races where extended fuel carries are crucial. Each size maintains the same insulation quality, so focus on your race duration and transition setup. Our sizing guide helps you decide based on your typical session length and aerodynamics.

Absolutely perfect for first-time triathletes! It's user-friendly with easy-clean stainless steel that doesn't hold odors or flavors like plastic bottles. The secure lid prevents spills during bumpy bike rides or fumbled transitions, giving you confidence from swim to run. As you train, it'll grow with you from your maiden sprint to full Ironman finishes.

Simply rinse with warm soapy water or run it through the dishwasher (lid hand-wash only). The stainless steel is corrosion-resistant and doesn't retain flavors, so no special treatments needed. Store dry to maintain the seal—proper care keeps it looking and performing new for seasons of races.

This bottle works great in most standard and wider aero cages found on tri bikes. The 12oz and 18oz sizes fit narrow setups, while the 32oz suits larger cage designs. If you have a specific bike frame, measure your cage before ordering—we can advise on compatibility to avoid race-day surprises.

Fill it with pre-chilled electrolytes or water for the bike leg to keep fluids ice-cold in hot weather. Store it securely in your aero cage to avoid drag on the ascent—test it during training to find the perfect spot. On race day, take quick sips during the bike and use the run to refill at aid stations.
