Looking for recommendations on under-shell long sleeve turtleneck crop tops that do not snag and/or run. The knit nylon ones are getting on my last nerve. We're on our third crop in 2 years. The first had runs all along the neckline half way through the year, after a uniform change this year, the very first competition the thing has already started to snag. If anyone knows of a manufacturer who makes a better product, please point me to them!
