I purchased this because my daughter was waking up sweaty, but she is comfortable in this and no longer wakes up sweaty.  It is a nice soft material.  It seems to run a little big, which is nice because we'll get more use out of it.  I purchased it in 6-9 month size, and it has mitten cuffs!  It is difficult to find sleepers in larger sizes that have the mitten cuffs, but would be nice if your baby is waking up with cold hands.  I also purchased the onesies from this same product line; the whole line is very nice.
