I Like your product.. the ice vest fits great and cools the core excellent ., and very comfortable.. but it’s just a little to heavy to wear in an event .., 5/6 pounds ad up over the miles in a triathlon… wonder if you could make one about half the weight with good cooling ? Was glad to practice with it .and try it . and I understand it’s for before an event or after. But If a person could make one to use during an event it could be a game changer ? Boulder 70.3 Ironman the temp was 90 and in full sun the hole race .. lots of athletes blew up their muscles locked up and people vomiting .. the intensity of the heat definitely took a toll on many .., thanks again .
