FC System called the "between-the-arms hydration system that answers all the needs of triathlon racing" in the August 2015 issue!
"In fact, we would go so far as to say this is without a doubt the best hydration product that Profile Design has put on the market, and one of a handful we would consider riding on a regular basis – and that probably says it all."- Aerogeeks.com
