Got this jacket for my 5 year old son after first trying the Aconcaqua. I was looking for a jacket that my son could put on and be warm enough in the winter even if he was only wearing one layer on top (he doesn't like having to layer up). This was the winner! Really well designed and constructed. Heavy, waterproof fabric, down-filled, tons of pockets to stash hats and gloves in, down filled hood that you could remove, fur trim that is removable (my son didn't want it), a cord to cinch up the bottom so the wind doesn't get in. I got the XS for my son which is plenty big, but wearable. The cord helps to ensure that the jacket isn't gaping open at the bottom while he's still growing into it. We are going through a cold snap right now (temps 0-15 degrees), and I feel comfortable sending my son out in this jacket. Highly recommend it!

I bought this jacket for my 5 year old son. This was meant to be his jacket for the coldest winter days. However, after receiving it, I didn't think it would be sufficiently warm for the coldest days. The down didn't seem particularly thick, the fabric seemed thin and not waterproof, and the jacket was not long enough to cover my son's bottom and hips. I ended up getting him the NF McMurdo parket which I am love. It is down-filled with heavy, water resistant fabric, and the parka goes partway down the legs. It also has a down-filled hood. I feel comfortable sending my son out into the 15 degree weather wearing the McMurdo. So if you are looking for an everyday jacket, the Aconcagua is nice enough. But if you are looking for a super-warm jacket, get the McMurdo.
