Keep my feet warm! Update: June 21, 2019Bought a 2nd to replace the now stretchy and permanently-greasy grip. This cable supports output only. Helps to look way more polished at work and for evenings on the town and to just feel WAY more organized. turn it to 70%+ and i couldnt hear anything. It is not a 4. I think this is just a preference and dependent on if you can get used to it. They are very comfortable, and I can and do wear them for hours at a time without any problems other than a slight heat buildup caused by the close seal around my ears. Out of all of UA storm pants, these are the loosest fitting and are COC compliant even under the new management. With the Hanes slippers, the cushioned insole extends beyond the bottom, so even if I step incorrectly, I have NO PAIN.
