Q.} Dear Kristin,

I'm allergic to down, but I like its compressibility. I’ve been trying to find a synthetic bag that packs as well as a down one. But do you know anyone who makes a hypoallergenic down sleeping bag or am I stuck with synthetics?

A.} Dear Greg,

Guess what? You are probably not allergic to down. You are likely allergic to the dust particles that remain in down that is not cleaned and processed properly. Or dust mites. Or mold that can grow in an im properly stored down bag. Some tips: Forget about buying a bag that’s labeled 750-fill power or under. Those are lesser quality downs that might have you sneezing and wheezing all night. If you opt for an 850-fill power or higher bag, you’re getting only the fluffiest down plumules that have been thoroughly cleaned.
