How long have you wished for a flexible drink flask that you can actually carry in your hand as you run? Our convenient, flexible Handheld ErgoFlask combines convenience with efficiency and ergonomics to make hydration ultra easy. Slide your index and middle fingers through the novel silicone loops for optimal grip as you're negotiating the trail. The wide opening allows you to fill the flask quickly at aid stations during a race, saving precious seconds. If you don't want to carry it, the smooth outer surface and slim shape ensure the trail running flask slides easily into a bag, trail belt or pack. Guaranteed leak-proof, it shrinks as you drink, preventing sloshing and taking up minimum volume when empty. The fast-flow bite valve is intuitive, perfect when your attention is focussed on the trail underfoot. Eco-friendly and durable, the flask is guaranteed 100% PVC and BPA-free so you can safely use it, wash it and use it again. Simply put it in the dishwasher for easy cleaning when you get back home. Keep the flask in hand and the task in mind, and the finish line will appear before you know it.
