3 Reasons to Choose a Sleeve Over a Hard Shell Case
Hard cases trap heat Hard snap-on cases block airflow, turning a fanless MacBook Air into an oven. This causes throttling and slower performance.
Sleeves protect without overheating Sleeves guard against scratches and dings during transport but let the laptop breathe while in use. Just slide it out when working.
Vented cases are a weak compromise Even vented or minimalist hard cases still hinder cooling. A thin neoprene or felt sleeve from Tomtoc or WaterField is a safer choice.
