We were very intrigued by the sounds of this comforter and were very impressed when we received ours. It has two layers. The first layer is a thin, lightweight layer that if sold individually would be considered a down blanket. This layer is light, fluffy and would be the ideal cover for the summer season when you sleep with the air conditioner on and want just a sheet and a lightweight yet cozy blanket. The second layer is a medium weight layer similar to what an all season comforter would feel like. When snapped together they create a very warm and lofty winter weight comforter. We were very impressed by how light this comforter feels even when used at the winter weight. You really can't beat high quality down that has a minimum of 90% down clusters. It is like you are sleeping in a cloud. Not to mention, how quickly it generates warmth in a matter of seconds. The snap buttons used to secure the two layers together can be slightly misleading because they initially look like buttons, but you will notice the button holes are too small to slide the button through. This is because they are actually snaps. The front of the snap is a clear plastic and the end of the snap is white. They are fairly easily pulled apart with a bit of pressure, and snap back together with a secure hold. These snaps may be difficult to use if you have arthritis or poor dexterity in your fingers or hands. The microfiber cover used for this comforter has a unique feel and is the first we have felt like it. It is smooth with a brushed finish to give it a peach-skin like feel. One tester thought it reminded him of a sleeping bag cover but not as shiny or slick. Another one loved the feel of it so much she didn't want to put it down. Overall it received many 'ohh this feels nice' comments. The only downfall to the cover is that it is a synthetic fabric which is not as ideal as an organic cotton cover for those who suffer from severe skin sensitivities or multiple chemical sensitivities. A plus to the synthetic microfiber cover is that it is more durable than cotton and is excellent at preventing down leakage. Due to the two layer design you will want to use this comforter inside of a duvet cover for a more polished and put together look. A duvet cover will also save you from frequent and costly trips to the cleaners; 2 layers mean 2 comforters to have professionally cleaned each time. Also for anyone with dust mite allergies, we suggest using a dust mite cover to further protect your comforter investment.
