This is an awesome cooling vest. It has full upper body coverage and it goes all the way down the lower back touching the waist. This is a big upgrade from the standard adjustable vest that came with my 6L chest cooler. I highly recommend it. I wasn't sure if my helmet would fit with the hoodie but it did, it was extremely effective although it will cool your head quite a bit. I recommend a valve and bypass so that I can turn on or off head cooling. The quality is also great and their customer support is excellent, I ordered the wrong size and they quickly shipped me a replacement in less than a week. They use Fedex and their deliveries take 7 days or less from China both times I ordered from them. What a great company, what a great product.
