[pct-l] Question - Keeping Cool on the Trail

[hiker97 at aol.com]

I have a question about some potential hiking gear.? Checkout the following website - www.coolineusa.com.

They have a light weight-long lasting?cooling vest ($250) that if it works would be worth its weight in gold.? Look at their video too.? 

What does everyone think of this product and its potential on the trail?

Cheers, Switchback the Cooler
PS: Refer to the movie Road House for the definition of the term Cooler.
