I purchased this headband when I started 75 Hard as a reminder mid-workout to keep pushing through. I ended up being super impressed with how much sweat this little baby retains. I ran 5 miles in the Virginia summer heat and when I took the headband off it was soaked (I could literally ring it out), and it kept it all from running down my face. Gross, but impressive. Love it!
I'm currently on day 51- if you're reading this: KEEP PUSHING THROUGH. YOU GOT THIS.
