When I saw the forecast for last weekend I decided to purchase a couple of neck fans for the trip. They were great. I found them fairly effective and really helped to cool you down while in an inside que by moving around the cooler air. They were less effective outside but still did supply some relief. We had four fans for our group of four. The folded nicely and fit well in a backpack. I also carried a portable charger to recharge them on the go.Do those neck fans feel heavy on your neck? They look so bulky to me? I'm trying to decide which ones to go with- we have ones that's attached to a lanyard but these look like they'd cool you off more...
