I recently migrated from a tropical country and now that winter is coming, I have a vague idea on how I can endure the cold months. I guess my pregnancy helps me to be a little warmer as back at my country; I set the AC to lower temperature than my usual preference. Anyways, now is the time for me to search for a good maternity coat. I like the first one here (as I am into natural and organic things) but I read in this article that people can be allergic to downs. My second choice is the red one made of wool which I know I am safe from allergies (have a piece or two back home). So, aside from the possible allergies, are downs really warmer than other materials?
