This was perfect for our winter baby - these sleeping bags are of excellent quality - the mesh vents on the underarms ensures they don't get too hot -- but also the handy snaps there too so they can easily adjust to suit when they are growing!! (make the arm hole smaller to it stops them slipping) this suit is still fitting my 7 month old! It also stops his legs from getting in between the cot rails too! These sleeping bags wash and dry so well. Very well made! (Posted on 23/01/13)
