Not as elastic as I hoped but it's warm
I bought the medium because my baby was actually a little smaller than the sizing rec and I wanted to be able to use it for the upcoming winter. My LO fits into it ok but the shoulder area is very tight and not elastic which I thought would be the case since we own two LTD sleep sacks and I loved how easy it was to zip her up before putting her down for sleep. For this one she's always squirming because of how tight the sleeves are when I pull it over her arms and the zip goes up quite high to her neck The warmth level is good. I have a 2. 5 tog sack and this suit and the sack is warmer than the suit.
