DIRECTIONS FOR USE: We recommend rinsing the flask thoroughly before first use. If you experience taste mix ½ a teaspoon of BAKING SODA with water, shake and rinse. Users have also found the following to be useful: Fill with MILK, shake, and rinse. Add drops of lemon. Let an orange peel or tea bag set in the flask for a couple of hours. To hydrate, simply softly bite the mouthpiece and press the soft flask and enjoy! The harder you press, the faster the liquid will exit.

Perfect no-leak running hand-held
Love this! Doesnât leak, easy to use and easy to grip. I can easily put it in my shorts pocket if needed too. Use it on most of my runs 10 miles and longer. I just bought another to have on hand. Great product!

The flask is made from durable, BPA-free materials that are safe and long-lasting. Despite being soft and flexible, it feels sturdy and capable of withstanding regular use. The wide mouth design makes it easy to fill and clean, which is a significant advantage over some other hydration solutions.The cap and nozzle design are both practical and user-friendly. The cap seals tightly, preventing any leaks, and the nozzle allows for easy sipping on the go. It’s simple to operate with one hand, which is perfect for maintaining momentum during activities like running or cycling.One of the standout features of this soft flask is its portability.

Too small for me
My fault for not looking at the description better. It did not hold enough for my needs. Instead of trying to carry around a bulky water bottle, I was looking for something easier to carry around in my “biggish” purse. This reminded me of a short baby’s bottle.

Awesome
Got it for skiing. Perfect for a jacket pocket. Just enough liquid to last 3-4 hours. Weighs nothing and shrinks as you drink. Perfect. Also, no plastic taste.

Después de probar varias marcas y precios, entre ellas las de decathlon, os puedo asegurar que esta pequeña y flexible botellita es cómoda de llevar en bolsillos de mallas o mochilas de Trail. Lo mejor de todo es que el agua NI SABE a plástico, como si me pasaba con las anteriores compradas. Muy recomendable. También he vomitado la de 500 ml.

Ho comprato questo prodotto per le mie uscite di allenamento per la corsa. Prima del primo utilizzo ho lavato la borraccia con detersivo e limone per togliere lâodore di plastica e lasciato a mollo per 1 notte. Con questo lavaggio non ho sentito il retrogusto della plastica/silicone della borraccia. Sicuramente richiede un lavaggio frequente, soprattutto dopo lâutilizzo. Trovo questa tipologia di prodotto utile perché flessibile e poco ingombrante. La capienza è perfetta per allenamenti non troppo intensi come i 10-15 km di corsa. Il corpo della borraccia, che risulta essere in gomma flessibile, risulta ben saldata con della colla sulla parte superiore (parte vicino il boccale); spero che duri nel tempo.
