Tailwind Soft Flask 500ml Slim

 Hydrapak UltraFlask™

Hydrapak’s UltraFlasks™ are crafted to perfectly conform to your body, compressing as you drink to minimize sloshing, bouncing, and spillage. This ensures you get every drop of that Tailwind goodness without hassle.

These flexible soft flasks integrate seamlessly with your current gear, fitting well with Ultimate Direction, Salomon, and Nathan vests.

Features:

• Transparent: Know precisely how much Tailwind you have left.
• Collapsible: Ideal for multi-stage or international events, shrinking as you use it.
• Lightweight: At just 38g when empty, it’s incredibly light.
• Pliable: Conforms to any shape – hand, belt, or vest – making it more comfortable than rigid bottles.

With a 500ml capacity, they’re perfect for runners using vests with two flask pockets. Fill one with Tailwind for an hour’s energy and the other with water, and you’re ready to go! This is the slim version, as some vests have longer and narrower openings for the flasks. Also, some ultra shorts have deep, slim bottle pockets, designed to fit perfectly with these soft flasks.
