I'm not an expert on what is/what is not virgin or remi or whatever. But I can vouch for this wig being 100% tangle free.

It is not heavy. It has thin wefts and has light density. Some people may not like thin wefts but I do because it keeps my head from getting hot. It does not come with combs and I cut off the elastic bands and sewed on 3 clips for better attachment.
I paid 89.99 for the Megan wig at my local BSS. It does have to be bumped with a flat iron after a week of wear. Let me find some file hosting and I will post pics of me in the wig.
