I absolutely LOVE these Loops! I've had Raynauds since early childhood and am always looking for something that will help when I'm at work without the bulk of other products. I really like to heat my wrists and these allow me to do just that because they're so easy to just slip back and forth to where I want them at any given time. Thank you SO much. Just ordered my second pair so I can leave one at work and have one at home.
