While it wears comfortable, it is rather warm.Not sure what the spandex textile ingredient (5%) is supposed to accomplish?Never seen it before in night shirts.It gives some more wear flexibility, sure. but not really needed.Buy a large enough shirt to begin with.my husband needed a long sleeved nightshirt and this filled all requirements nicely.Ordered a small and it's not as fitted as I would like. But I'm also very petite.a new concept for me....get rid of the underwear; fits well; great materialVery comfortable, great style and fitMe gusta este camisón para dormir de hombre, es deportivo y su material elástico. Se ve elegante; lo único es que la costura frontal, debajo de los botones, arruga un poco la pijama, creando una línea de arriba a abajo. No obstante, se ve bien y me gusta mucho.I bought this shirt for my husband - he's been wearing it for about 10 months and he loves it. It is a nice, thick, quality knit fabric, and the shirt itself is well-made. The sizing is right on. Really nice product.
