OspreyDuro Dyna Handheld Unisex Hydration Dark Charcoal Grey O/S

I used their smaller model for years and loved it. I was excited to see that they made a larger one. They ONLY thing I am disappointed in, is the extra strap that is on the smaller. There is an extra strap that helps holds the bladder in place. With this bladder being bigger, you would think that they would have kept that extra support. However, I am still happy they have a larger one.

C’est un accessoire utile pendant les courses. Design ergonomique. Bon matériau de la bouteille. Très facile à utiliser

riktigt bra! Matchar förväntningar och är smidiga att annvända!

I have used this product for 7 years without issue. Just bought one for my brother that lives in the desert. He takes it on walks with him. Th keeps your hands free while providing a half liter of hydration.

First off, this is by no means a bottle, call it what it is - a water BAG. Once you've had a little to drink the rest of the liquid will slosh around in this shapeless bag requiring you to bunch it and hold it with your hand. To make matters worse the "bag" is attached to its holster with a flimsy shot cord where the cap meets the bag. Any sudden movements (I'm running here) and it will come loose and fly to the side of the road/trail. I've had to go back and get this on several occasions once it was empty because I didn't realize it fell. The last fall it landed when full, directly on its nipple end and the plastic cracked. I tried filing a request for help on their website since they have a guarantee but the form keeps coming back with errors. Giving up and going back to Nathan bottles
