I purchased the headband and wide wrist cuffs. The headband (fabulous purple color) I wear almost daily at work (9 hour shifts standing/walking nonstop hospital inpatient Pharmacy), the ice packs only last 2-3 hours so I bought extra to keep in the freezer at work for a change out. It's been really helpful keeping me cool! And the ice packs don't sweat as they warm up, so I'm not all wet down my neck. I wish the wide wrist cuffs were wider in circumference, they said for 8" wrist, which I am, but cuffs are really tight on my forearms with the ice packs inside. They do help me stay cool, but not very comfortable or easy to get on, and then get the ice packs in them, especially if you're alone. But I do recommend!! I have Multiple Sclerosis so keeping cool is a must!!
