I bought DD (3yo) the M&S thermal vests as per usual this year online, however this time they were different - more t-shirt style and instead of half and half cotton and viscose, there was 50% cotton, 25% viscose and a wopping 25% polyester. They caused a nasty itchy rash for poor DD and I've taken them back, but now I can't find any to replace them and they have no stock in her size in last year's version.
Does anyone know of any thermal vests without polyester? I know M&S do the long sleeved version, but I think they are too hot tbh, and pricey.
