I just order this and it be go right back . my 2 year old , be below or average height and pretty skinny too and the bag be still too small . he do not have much leg room width wise either . it be a good light weight sack if you order one size up for you tot . too bad mine be too big for it . i really want to like it . update : i order the merino wool kid 2-4 for my tot and it be PERFECT . pricey but perfect . lot of leg room and it be snuggly warm .
