The materials are very nice and the construction is high quality.  I like the wrap feature because it prevents having to pull a soiled suit over the baby's head if they have an accident.  It also helps because it is less jarring to change on a sleepy or spit-up prone baby.  The extra row of snaps and sizing works well.  My baby was premature, so he is skinny - these fit fine.  He is 4 months adjusted and in the 25% for his adjusted age (6 months chronological and in the .1% for his actaul age).  The fit reminds my husband of the star trek next generation uniform.
