I have NOT yet tried this product………..
However I have looked at it……
https://gobiheat.com/ (click near top of the page to see their new cooling Vests)
The down side I believe it the added weight
The Water cooled vest weighs in over 4 pounds when you add it all up….
What does everything weigh?
This is our most common question! The empty vest, including the piping and pump, weighs 1 lb 12 oz. The 6 oz battery pack fits comfortably in the pouch at the back of the vest. We recommend adding one 16 oz frozen ice core (1 lb) and 16 oz of cool water to the reservoir for optimal circulation.
Sitting in a chair on a Bass boat might be OK
but up moving around and even casting lures might be an issue
Mean while I am using wet Towels and Hydrating a lot !!!
Just my two cents worth in the discussion 🙂
