Hi. Is it possible for fleece to lose "loft" and thus its insulative properties through extended storage?

For example, I have a couple of winter fleece items which are tightly rolled up and placed in a stuff sack. Since I do not need these items for the fair weather seasons (spring-summer-autumn), I am inclined to leave them in the stuff sack until I need them again (next winter).

Of course if the constant compression resulting from being stored in a stuff sack for so long negatively impacts my fleece items (i.e., reduces "loft"), then I may have to resort to some other storage method (good 'ole hanger).

I know its not a good idea to leave a sleeping bag tightly packed in a stuff sack for an extended period of time, and the same could probably said of insulation layer jackets/parkas, but what about fleece?

Thoughts?

Anyone?

I vote no.

Chris, my fleece items have matted over time. Especially my extra fuzzy polartec thermal pro garments. This is the result of sleeping in them (back sleeper), and wearing a pack over them. I don't discern a difference in warmth though but who knows. But i still try to avoid excess compression when I can.
