The neoprene really traps heat and makes me sweat during my morning cardio session, which is exactly what I wanted for toning up. Four weeks in and my upper arms already feel noticeably firmer when I flex.

Wearing them during my evening walk, I could feel the heat building around my arms almost immediately—the fabric really traps warmth. They're snug but not suffocating, and I love how easy they are to slip on under a hoodie. Perfect little boost for toning up before summer.

Finally got these in the mail and wore them during a home workout — they stayed put the whole time, which is more than I can say for other trimmers I've tried. The neoprene feels thick but breathable, so my arms didn't get overly sweaty. Exactly what I needed to feel that extra burn while toning up.
