Running flask?

  • Familiarity: I've used it once or twice and have initial impressions

I currently use the Ultimate Direction Fast Draw Plus for distance/trail running. For various reasons, I wanted to try something new. There isn't anything wrong with the bottle per say, but I don't like it. I don't like the shape. Besides feeling like your running with a big flask in your hand, it just isn't as comfortable to carry as a round bottle. I assume it won't be as protective. I don't I like the adjustable hand strap either. When it's loose it comes completely off the top of the bottle. Could argue it's easier to get it on your hand that way, but I don't like it. The mouth piece it a twist type and is no problem to use once you get used to it. Overall, it's a quality product. I just didn't like the features of this particular bottle.
