Warm But Pills
Size: Full, Color: Purple
Overall the Intel Design jersey knit bed sheets are just like sleeping between a huge cotton blend t-shirt. It's soft, cozy, and warm to the touch. However after only two washings, the fabric begins to pill significantly and a lot of lint collects in the clothes dryer's lint trap. The new sheets now look five years old and stratches the skin. The warmth does provide longer periods of restful sleep. Not sure how long the fabric will last, as it appears a bit tired and worn. The initial purple color also appears noticeably duller. Good value at first, but probably will replace in a few months, so not much savings in the long run
