Description

Tailwind X Hydrapak Soft Flask

Hydrapak's UltraFlasks™ are designed to conform to the shape of your body, compressing as you drink. This means reduced sloshing and bouncing, less spillage and an easier time sucking out that Tailwind goodness. 

The flexibility of the soft flask means it can fit into your existing gear: successfully tested with Ultimate Direction, Salomon and Nathan vests as well as countless bicycle jerseys and backpacks. Plus it's 100% BPA and PVC free and works with frozen or hot liquids (max temperature is 60° C or 140° F).

  • Clear Plastic - no more guesswork towards the amount of Tailwind left
  • Collapsible - Perfect bottle to use on multi-stage events or international events, it's only as large as the Tailwind being carried
  • Lightweight - weighing in at just 38g once emptied the flask is light as a feather
  • Pliable - Conforms to any shape, be it your hand, belt or high-tech vest
  • Dimensions: The hard plastic top of the flask measures in at 8.5 x 6.5cm wide and stands 7cm with the rest of the flask being able to collapse in to the hard top when empty
  • Capacity: Holds up to 500ml/17oz 

 

But don't take our word for it, read the reviews

    Soft Flask

    I think this is one of the best soft flasks on the market. I have had others and they all leaked right away. They are not cheap but they work!

    Great purchase!!

    Love this soft flask. I got two to replace the ones that come with my hydration vest. These are high quality and I really like how easy they are to drink from. Previous bottles I’ve had could easily get stuck in a “closed” position but there are great and don’t leak! Really happy with these bottles.

    First soft flask might have converted me

    Posted by Ben H on 4th Jan 2021

    Like the title of this review states, it my first dive into soft flasks. Coming from the hiking world, semi-hard sided water bottles are the norm for their toughness and their ability to fit into pack side pockets without contorting your arm or taking off the pack. But this 1/2 liter soft flask easily fits into a side pocket when full and compressed down when empty to fit anywhere in your pack. It weighs practically nothing and cleans easily. The opening is wider than most water bottles, which makes pouring powder mixes easy while on the go.

    love all the performance from the flask

    you cannot go wrong with this item, long distance runs needs an extra bottle with tailwind , the soft flask works perfect, you can fill with any flavour, collapse in the vest and use later filling with water, no leaks no rips, perfect tool for the runs!

    Functional and great product

    Posted by Zach on 29th Sep 2020

    It works. And let’s be real, when it comes to long distance running, that’s all we want. I regularly run with my North Face vest and this water bottle fits nicely, forms to your chest/rib area, and has absolutely no leaking/swishing at all.

    Great water bottle!

    I love this water bottle. It fits in my side pocket and I don't even know it's there; seals tight so no leaking. It also deflates as you drink so takes up less space as it empties.

    PERFECT!

    Works like a charm! Other brands leaked all over me, this one just works. I've just ordered another one. Thanks Tailwind for a great product.

    Best Soft flask on the Market

    Posted by Seth Bearden on 23rd Nov 2019

    I use this flask for all my adventures. It is perfect for handheld or placing in a hydration vest pocket. The lid threads on easily and is simple to fill. I use these exclusively! Thanks UD!
