micoach is all you need to get the results you want.
I cant say enough how much I love this. My 18 month old son is 24 lbs . He fits into it perfectly. There is not a ton of extra room around the waist. I ordered the 18 month size and it fits true to size. Love it. If you have a big kid I'd buy a size bigger like 24 months for an 18 month old. Our little guy is just that
This vest fits well over a climaheat running top and is great for keeping warm without overheating. It's extremely lightweight and not at all bulky. The only negative is that it can't be left to dry naturally after washing. It needs to be tumble dried with tennis balls in the dryer in order for the down inside the layers to properly fluff back into shape.
Great, low-profile piece for layering or a stylish accent to a casual outfit. Fits trimmer than most Adidas outerwear. I can wear a thin hoodie under it but not much more (I'm 5'10"/177cm and 170lbs./77kg, trim upper body, about 38"chest and 30" waist. I bought a small to wear under heavier jackets rather than over a fleece etc. so I'm happy with it.) It's fairly breathable yet retains a moderate amount of warmth to the core of the body. It's not very waterproof, however, which is fine for me but something worth mentioning.
