Shop the Sustainable Athleta Collection Olympian Allyson Felix Calls "Amazing"

Athleta gave me the Sonic Mint Lightning Crop Tank in SuperSonic ($59) to try out and I loved how it looked. I had previously never worked out in a crop top in my life, but I felt confident in this Lightning Crop paired with the high-waisted Colorblock 7/8 Tights (featured ahead). The waist of the Colorblock Tights was high enough that it left just a sliver of skin, which is all I'm comfortable showing. It held up during our treadmill sprints and intervals and was lightweight and cool.
