I was just at one of our local gear shops, here in Asheville, NC, and noticed these new bars.
They are made locally, in Boone, NC, from whole ingredients, but what really impressed me was the caloric density. We chose a walnut dark chocolate cranberry to take on our hike today. It comes in at a very dense 140 cal/oz.
It's vacuum sealed, so even if the chocolate were to melt, it won't be messy, and a few minutes in some cold, flowing water should solidify it.
You can get them direct online at Parr Foods
