My husband now has 3 sets of these pajamas in different colors and we love them! He is 6' 5" tall and medium to large build, and the 2x fits him perfectly. They are light enough to be worn during the summer months but substantial enough to make it through the winter as well.
He has owned the oldest pair for over 2 years now, and it's probably been washed between 30-40 times on the delicate cycle using cold water. The fabric around the wrists and the ankles is just starting to get slightly rough - it isn't quite fraying because they are made of silk fabric, but it's starting to get a little fuzzy. Still, my husband is very rough on clothing and I am exceedingly impressed with how these pajamas have held up.
They are well worth the price, and do stand up to daily wear and regular washing. Highly recommend to any man who wants a nice set of pajamas!
