I LOVE these. I put them on my Quick Stow flasks on my hydration pack and it has made my runs so much easier. I just fill the bottles and leave them alone. It will make it much faster to get through aid stations then using a bladder and the tops even make it so I can share water with my dog on runs with her (I just squeeze the top and spray the water towards her, she doesn't actually use the tubes).

Muy recomendable para flask camelback, ideal. Además, va super bien cuando vas en competición, porque no pierdes tiempo en sacar y meter el flash para poder beber, con lo que es super cómodo.

Top pour avoir les mains libres lors d’un trail. S’adapte parfaitement bien et assez costaud.

Bought these to add to my soft flasks with my vest. I was finding it awkward to drink just out of the bite valves that come as standard so wanted straws to see if it was easier. It is an absolute life saver in terms of taking on fluids. The only drawback now is that I drink too much.Tip, the bottle tends to sink into the holder as it empties so I just tick the straw under the vest rather than under a strap because once the bottle drops so far it doesn’t sit under the strap anymore.Great bit of kit!

Fit my flask well and no leaks after a month of daily use
