Hydration on the go!
I love this flask it fits nicely into my flip belt when running and great to use on my long runs. I have had no problems with leakage or bursting. It's well made and does the job perfectly.

Perfect for using with a running vest
Quick delivery and great for using in a running vest. Ideal for holding water, preworkout, electroytes and other solutions. High quality seal that you bite down on to release liquid. Make sure you clean them and keep them in the freezer between uses to avoid them going all slimy.

Bought for trail running but have multiple uses
Super useful for out using out and about. These were bought for trail running and work really well. No leaking and super easy to use while on the go. I’ve also found them to be really useful when out and about in general. They fit into my small handbag really easily and I’m not worried about them leaking because of the quality. They’re also super light weight so only really carrying the weight of the water inside them. Highly recommend.

Great Idea... But then comes the taste!
I really wanted this to work, but what ever I do I just cant get past the horrible taste these bottles give. Great idea but really isn't for me due to the taste.

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 l’odore 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 l’utilizzo. 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.

Petite gourde très pratique, achetée pour mes séances de running. Elle rentre parfaitement dans ma sacoche afin d’éviter d’être encombrée. Solide et efficace. Je recommande.

Premetto che l’ho comprata per il mio cane, andando in giro d’estate avevo bisogno di una borraccia comoda da mettere in borsa , che fosse piccol, si potesse riempiere e pesasse poco. Molto pratica, non perde se messa in borsa, unica nota negativa , non la utilizzerei io perché purtroppo l’acqua sapeva un po’ di plastica

Taille parfaite pour s'hydrater sur un running de 10 km grand max mais il m'a fallu des dizaines de rinçage avant de me débarrasser du goût de plastique très présent.
