All one piece, one buton flap back, snug and warm.
Details:
These are some of the best unionsuits we have seen - 1x1 rib knit, ribbed cuffs at both the ankles and wrists and a really nice neck. One button flap bottom which can be sewn shut for the ladies. These can be done any way you want. Solid, varigated or tiedyed! Great for sleeping in - I love mine! Like sleeping naked but warm.
