What Our Gearhead(R) Experts Are Saying:"I threw this over a sports bra and leggings before an early class, and it instantly made the whole outfit feel finished. The thumbholes kept the sleeves in place through every stretch without me ever adjusting them."The Performance Slip from Daughter Lessons is the layer that turns any active outfit into something worth a second look. Made in a breathable performance mesh, it slips easily over a sports bra and leggings for a studio session or drapes over a onesie for an easy, elevated look on a low-key day. The thumbholes keep sleeves in place through every reach and stretch, so you can move through a warm-up without a second thought about your layers.
