I worked out in the leggings and only have positive reviews, especially for the leggings!! They are super soft but not super buttery (like vuori, lululemon align leggings and zentry nike leggings) which means they held up on my body - I never lifted them up during class. I felt supported in a way that is comfortable. Typically, other supportive leggings have too much compression (alo). Also, I love the fit. They are high waisted (it's just more flattering and I like my midline feeling supported) and I love the slight ankle crop.
The sports bra was the same vibe. Initially I was more hesitant because it looked more structured (because of the padding) but it didn't feel "heavy". It felt very comfortable even for someone with smaller boobs in less need of "structure".
You’ve nailed the comfortable AND performance mix for both those pieces. I also love how simple the aesthetic is.
