We got the 0-3 months size for our son born late September and will get a full winter out of it. It fitted our small 2 months old with plenty of room to grow and is now just a little snug on our 5 months old (while we has moved on to 3-6 mo. pjs). The zipper is good quality and the opening makes it easy to take baby in and out of the bunting. The hood is large and fits nicely on its own or over a hat. The fleece lining is super soft but only goes down to mid-back. There is no fleece in the arms or legs. The fold-over cuffs are genius for babies! It is only the shell material that folds over (no insulation), but it is perfect to secure mittens and socks in place. The shell fabric is somewhat water resistant but not really meant for sustained snow/rain. Down insulation makes it light and packable. I usually roll the whole suit in the hood to throw it in my diaper bag when on the go. We have used it in temperatures up to lower 40s with only cotton pjs underneath and down to low 20s with an extra layer of fleece. Works great in both the stroller and baby carrier. Overall a great product at a fair price!

Bought this as a gift for my four month old nephew.
It's super soft on the inside and the down is thick and insulating.
Best feature by far is the fold-over hands and feet...keeps little fingers and toes nice and toasty.

I think the feature I like most about this snow suit is the fold up hand protection. It keeps my kids hands warm when we go for hikes in the winter and they stay covered unlike gloves that he can take off

We got the 0-3 month size as a gift, and we love this bunting so much that we just bought another one in a bigger size for our growing tike. The fleece lining is super soft, the down is cozy warm, the hood fits perfect, and the hand/foot covers make perfect sense for infants. This piece is PERFECT for cold weather and you can't go wrong at this price.

My 6 month old was able to enjoy all of our family activities in the mountains and stay toasty warm. I purchased the 12/18M for my son who is 29" and 23.5#. We used it on a bluebird day at 30 degrees, ice skating at night in 10-15 degrees and watching big brother play in the snow on a cloudy 20 degree day. It was easy to get on and off. I was able to use the hood or put a different hat on my son with no problems. Best of all, he still fit comfortably in our Ergo carrier with me wearing a winter jacket (picture shows a basic Columbia fleece, but I also used it with a heavy Burton shell on top of the fleece). In all situations, his only layer was basic cotton footed PJs. I think he may have gotten a bit warm on the 30 degree day. :)
