What I love about this product is, it’s pretty compact. There are two pieces, one is a hard plastic piece that fits snuggly in place with a sprout. The sprout can be used alone or extended with a tube that fits into the small pouch.
The only issue I have with it is that I can’t fit it in my running pouch or my bike bag. It will fit in the pocket of a cycling jersey but only an oversized pocket. That’s is why I typically leave it in the car.
But I did try it out and was surprised at how well it worked.
