I have purchased many turtlenecks and of all I have worn, Bean's Pima Cotton Turtleneck is the most comfortable, best fit, smoothest texture, and nicest flow over my upper body. The neck keeps its shape without being tight. These shirts look both dressy or casual. I like the cuff-less arm for a neater look. The slight fit gives them a trim look tucked into pants and skirts or worn out.
LL Bean's pima cotton T-necks are *the* best. They are silky and soft, cut well, and wash great. I bought this for my mom because I have several. She loves it.
The shirt is very lightweight, yet warm and comfortable. The neck isn't too tight. It was on backorder when I ordered it but arrived in my mailbox exactly when it was promised.
