"Down alternative" is a misnomer. Down comforters breathe, so they stay warm in winter but cool in summer. This comforter traps heat like nothing I've ever experienced, so that even on a cold night it's a little too hot. Might be good if you live in a much colder climate, but too much even for temperatures in the 40s, in my opinion. And not in any way a "down alternative" -- just a regular comforter. It's also significantly lighter weight than a down comforter, which might be good for some but is not at all what I'm looking for.
