It could simply be a reaction to the chemicals that were used in producing the material, or other stuff in the factory.. I tend to have a bit of a "tightness" when opening new stuff sometimes. (perhaps I'm just nuts?) Anyhow.. I've got a down comforter and do just fine.. although, you might consider one of those allergy covers, just in case.. I'd assume you'd be okay after that, if not, well.. it's better to have tried, right?
