I really like the redesigned cool cuffs. The fabric has a nice stretch and the cool packs stay securely inside the cuff pocket while wearing. I wore them last week on a very hot day as I gardened outside. The frozen packs lasted about an hour before the cooling effect rapidly decreased. That was perfect for me, as I hadn't planned on gardening for more than an hour anyway. Since the cuffs come with an extra set of cooling packs, I could have easily popped a new frozen set in and continued working. I threw them in the washer and let them air dry to ensure the elastic component of the fabric would not be damaged by heat drying. They came out like new.
I give these a five-star rating and I think buyers will love the improved design. The only negative for me is that I have very small wrists (5 1/4"). While the cuffs were not loose and made good contact with my skin, the fit was more snug when I first put them on. As the cool packs began to melt, the cuffs felt just a little bit looser, but they still maintained their cooling effect.
