The bag is great finish, the cooling effect is nice and effective. Compared to the usual cooling vest, the bag is compact, nicely balanced, confortable to wear, and the cooling capacity is just right for my needs.My use case is to bring the cooling bag at work in the morning, the ice bladder stays cold the whole day inside the insulated bag. I then can use the cooling capacity of the bladder after on my way back from work, inside train or subway where AC is not guaranteed. My travel time can vary from 45 min up to 2 hour.
