Hi all, Seeing that the parents on this forum are quite knowledgable and helpful, I thought I would pose my question here. I'm in the market for an Ergo carrier. My friends in Hawaii swear by them, mostly because the company was started there. My question is, which model: the Original (100% cotton), Sport (35% cotton 65% polyester), or Performance (98% polyester), did you find was most suitable for the UK climate? I was told the cotton one made it too warm for both baby and parent...but this might be good for the winter weather here. So which model did you end up purchasing? And did you pick up the infant insert as well as the weather cover too? Many thanks in advance for your thoughts! PS And if you happen to have one for sale, please PM me as well.
