Its getting chilly now and with the heater off, I've stayed very warm under this down comforter.  It makes getting out of bed a little harder unless the heat is turned on.  Its not heavy at all and I grew up with Mexican blankets, extremely heavy (the really good ones) and they break your machine when you try to wash them.

Pros: This down comforter is light and feels great to the touch.  I love the crisp white, looks good without a duvet cover.
Cons: I haven't washed it to see if it bunches in the quilted squares but it did say to use a clean tennis ball and roll out, however a duvet cover will help prolong in between washes.
