The sleep kit includes a top sheet, bottom sheet & one size fits all sleep cap. Before purchasing, we recommend you purchase the sleepcap individually to test it out before committing to the more expensive kit. Your brain will feel so protected that you will want full body protection at night. Then with the extra cap, we recommend you snip off the ties and tuck it as a hat liner in your favorite hat. Our patients love this economically efficient advice to prevent buyer’s remorse.
