First off, what's a shiver?
A "shiver of sharks" is a term used to refer to a group of sharks that are swimming together. As Thresher & Co. was in the initial brainstorming, one of our key ideas is to unite parents that have a passion for sharing the outdoors with their kids.
The phrase of 'Rep Your Shiver' represents the continual focus of adventure parenting and the connection with the next generation and the outdoors!
