The nightshirts are made from polyester knits, cotton flannel, and coral fleece. One polyester blend listed is 95% polyester / 5% spandex.
You’ll find short-sleeve pullover sleep shirts and long-sleeve options. Long styles appear as button-down flannel or pullover fleece, while many knit sleep shirts are short-sleeve pullovers.
Common necklines include V-neck and round (crew). Several sleep shirts also use a Henley-style short button placket at the front.
Sizing ranges vary (S up to 3XL in some listings, M–3XL in others). Fits are described as relaxed, loose, or regular, and some listings are labeled Big & Tall.
Many listings note side pockets; some knit or Henley styles list a chest pocket, and the plush fleece specifically mentions two side pockets.
The flannel listing shows chest fits from Small (34–36") up to 3XL (54–56"). The fleece listing uses the same Small–3XL span, with larger sizes noted using 2X/3X labels for the upper end of the range.
