Sea toSummit's Ultra-light Aeros™ Pillow Case can be filled with spare clothes or a down jacket as a minimalist pillow alternative.
 
To prevent slippage during the night, the AerosTM Pillow Case’s base fabric is compatible with the hook-and-loop fastener patches that have come standard with all Sea to Summit Sleeping Mats from mid-2019. Current AerosTM Pillows can be placed inside the AerosTM Pillow Case for seamless integration with this new feature.
