Abbey by Envy offers you the most recent technology, combining a new ultra soft silk chiffon lined cap with trademarked Envyhair fiber made of 30% human hair and 70% heat friendly synthetic. Soft, comfortable and 100% hand-tied styling puts Abbey in a league all her own. The combination of human hair and heat-friendly fibers is very practical. You get the versatility of human hair, but with less heat and all these beautiful colors (and even grays!), so you won't have to "color" your Envy 30% human hair wig.
