Query: Yummy and moist.

All the cliffie bars share these traits: very moist, chewy and easy to swallow. It makes a terrific afternoon snack or for quicker recovery from a workout or jog. The other energy bars I've tried such as PowerBars are either too dry and hard to swallow or sticks-to-the-teeth. I also like the Clif packaging and learning about Soy Protein. One Tip: Sometimes it's hard to open, just flip it over and open it from that end! If that doesn't work have a friend rip it open with their teeth - you know that's a friend to keep!
