Nathan Running Handheld 12oz and Insulated. No-Grip Adjustable Hand Strap. Reflective Hydration Water Bottle.

This item is not insulated. I am very disappointed about the false advertisement.

The very first time I used this water bottle it leaked everywhere :/ I have tried several times and every time it leaks. Very disappointed as I was looking forward to this new bottle!

I wanted to love this bottle. It's a great size and the price was right. Unfortunately, it's a bit leaky. And, unless you have monsterous hands, the proportion of the bottle make for an awkward grip. It's ok, but not the best handheld running bottle I've had.

Works well with my med/large male hand, with pulling strap tight I do not even have grip it. Comfortable shape for carrying.With top on tight, no leaks.Longevity - no problem after several runs.

Espero si sea resistente el material de la funda ya que aparentemente está frágil

for a 6 K product the build quality is extremely poor... waste of money
